What Is Drupal and Benefits of Drupal Web Development


4gWhat is Drupal?

Drupal is content management software. It is a free software package that allows anyone to easily publish, manage and organize a wide variety of content on a website. It means you somehow “manage content” with it.

It uses modules to allow site administrators to organize and display content, customize appearance and manage routine tasks.

It is open source software maintained and developed by a community of hundreds of thousands of users and developers. It’s distributed under the terms of the GNU General Public License (or “GPL”), which means anyone is free to download it, share it with others, and contribute back to the project. This open development model means that people are constantly working to make sure Drupal is a cutting-edge platform that supports the latest technologies that the Web has to offer.

Hundreds of thousands of people and organizations are using Drupal to power an endless variety of sites.

Types of sites that Drupal can be used for include:

  • blogs
  • personal or corporate Web sites
  • portals
  • forums
  • e-commerce sites
  • intranets
  • resource directories
  • social networking sites

Why It Is Important to Thoroughly Test Your Website Before Launching

ffA large percentage of modern users accesses websites on their smartphones and tablets. Likewise, many users also buy products/services from web stores accessible on their mobile devices. So while planning and developing a website, you need to ensure that it delivers quality user experience across a wide variety of devices. At the same time, you also need to focus on the website’s user experience to keep the visitors engaged and convert them into customers. At the same time, it is also important to get the user interface (UI), functionality, performance and user experience of the website tested thoroughly before its launch.

Advantages of Testing Your Website Rigorously before Its Launch

Determine Cross Browser Compatibility

While building websites, developers have to use several web technologies. Some web technologies are open whereas others are not supported by all web browsers. So there are always chances that your website may not run seamlessly on all web browsers. When to perform elaborate cross-browser testing, it becomes easier for you to check how the website runs on individual web browsers. The developers can further work on the flaws identified during the testing process to make the website deliver quality experience across many web browsers.

Assess the Website’s Mobile Friendliness

You can reap a number of benefits by optimizing the website for mobile devices. When the website is accessible on mobile devices, it can keep the visitors engaged and covey the required message. Also, the mobile-friendliness will make your website rank higher on Google search results pages. So you must assess the website’s look, feel, features and performance across a variety of mobile devices. The testing will help you to retain the customers and achieve higher conversion rates.

Evaluate Its Features and Functionality

The features and functionality of your website will have a direct impact on its user experience. Often users abandon shopping carts or switch to another website if you website does not function flawlessly. So the features and functionality of the website need to be tested individually as well as an integrated unit. You must perform thorough performance and functionality testing to reduce shopping cart abandonment rate significantly.

Determine Its Performance under Varying Loads

The number of website visitors differs on a daily basis. Normally, the eCommerce websites get more visitors during holiday seasons. Also, you can attract more website visitors by offering attractive deals and discounts. But you need to ensure that the website is effective in handling a large number of user requests simultaneously to get more sales and revenue. You can always perform elaborate performance and stress testing to ensure that your website performs seamlessly under varying user loads.

Ensure that Your Website is Secure

No customer will but products or services from your web store if it is not 100% secure. You must use advanced security techniques to keep the sensitive customer data safe. Likewise, you have to use encryption techniques to store and share customer data more securely. At the same time, you also need to ensure that the third-party services and extensions used by the website is not affecting its security. On the whole, you need to perform comprehensive security testing to win the trust of customers and boost your business’s goodwill.

Avoid Redesigning Cost

If you launch the website without testing it rigorously, there are chances that you have to design it each time users report any defect or bug. But the web developers can easily and quickly eliminate the bugs or defects in the website when they are identified during the testing process. Thus, early detection of defects will help you to avoid redesigning cost in future, while protecting the online reputation of your business.

Engage and Retain Customers

Nowadays most users find websites through search engines and social networking platforms. So the quality of the website will have a direct impact on its conversion rate. When you test all aspects of the website thoroughly, it becomes easier for you to deliver quality user experience. The quality experience will further encourage the customers to promote your website on social networking platforms. Thus, you can always retain customers and achieve more online sales by getting the website tested rigorously.

 

Remarkable Wonders of Flash Technology in Modern Websites

rfIn the modern era, for an organisation, be it commercial or non-commercial, its face and overall image is best reflected in the website. On this score, the decisive factors include visual artistry, integrated sound, ease of use, and the overall uniqueness. And these qualities are achieved with the aid of Flash technology in the design and presentation of the website.

Thus, an eternal demand exists for the products and services rendered by a Flash website designing company from corporate, governmental and other entities. Websites of such a design are more responsive as compared to others since attractive illustrations, images including animated ones, graphics and icons speak more than words. Indeed, the Flash websites are very much ideal for educational modules and training packages. They prompt the inquisitive mind of every visitor to ascertain more information and thus literally undertake a full tour of the website. And in the process, the number of hits witnessed on a particular website is bound to reach newer heights.

These websites have proved to be a boon for the functioning of SEO, SMO and also the webmaster. For instance, with creativity and vibrant colours as its forte, a company engaged in Flash website designing can catch the imagination of a visitor from any part of the world, merely by the click of a mouse! As noted earlier, applications of this New Media in educational packages and also games with Flash-aided animations have worked remarkable wonders.

A study conducted by Adobe has revealed that Flash has impacted 90% mature markets as such it has become a catalyst for the trade and industry. On its part, apart from websites, this technology has boosted a wide range of slots and fields like –

  • Corporate profiles
  • Campaigns and Banners
  • Logos and Designs
  • Photo Gallery
  • Supplementing Audio-Video Presentations
  • Gaming portals
  • Maps

Considering all these aspects, it can be rightly asserted that it is the lively website that lends and also reinforces the brand or image of any entity under the sun. Hence, it is very essential to entrust the design and development of the website to a company that is manned by qualified and expert professionals with acumen of foresight and farsightedness. Their talent enables conceptualisation and visualisation of positive impact. Even a casual viewer or visitor will be impressed by these aptly designed websites.

The art of graphics (static as well as animated) happens to be the base for all Flash applications. In this context, a couple of years ago, the Confederation of Industry had undertaken an exclusive study on the relevance of graphics and published the findings titled ‘Design Report’. In this, it was clearly highlighted how graphics are extensively used in numerous other media and fields such as –

  • Print design of brochures, books, leaflets, flyers, posters etc.
  • Packaging design
  • Branding strategy
  • Visual communication
  • Product graphics
  • POP graphics
  • E-catalogue design
  • Miscellaneous designs such as menus, newsletters, signage etc.

In a nutshell, it is the quality of a graphic design that holds the key to success for any business entity in the corporate world.

 

Since Humans Are Flawed Can We Use AI Computers For Our Leadership Decisions

lNot long ago, I was speaking to a Leadership Expert about what makes a good leader and what makes a bad leader. Inherently we all know there is a difference and yet it is hard to define or even put a set of rules to it, the difference is often fuzzy and gray at the borders of good and bad, like anything I suppose. We all can look the other way if a less-than-optimal leader leads a team to success, and sometimes we can even say someone is a good leader even if the team fails.

So, maybe we need to talk about definitions, for if we can define it, we can replace the human weakness and program an AI machine to do it! Wouldn’t that in the end be best for all concerned, rather than deals and arbitrary rules set forth by avoidance and politics? Think about that for a moment.

Now then, regarding humans being flawed and making mistakes, sure, true enough and we can eliminate those perceived mistakes using Artificial Intelligence. Is that a good reason to remove the leadership hierarchy and replace them all with artificial intelligent computers and robots? That would be interesting to see the US Congress with no people in it, or the EU or UN chambers with lots of robots or just computers calculating the needs of humans via a networked central nervous system of input from across the civilization.

Still, humans have some other viable traits when it comes to leadership, as a good leader can recover from their mistakes and make a bad situation become an opportunity, I used to do that all the time. Those who don’t try, don’t make waves, play it safe, but never find the innovations in the market so their companies run redline like all the other NASCAR race cars going around the same track, with the same rules and going the same direction, that’s definitely thinking inside the stadium and although supposedly “on-track” it’s those who charter a new route who create change – they are the ones who own the game, question is can they get enough followership to make things happen, and will that group follow a fearless leader through hell without stopping to do something great? Hmm? Another interesting topic – and even Tom Peters would stop to think on this one. So great point – people are flawed, maybe that’s a good thing, after all ‘junk DNA’ isn’t really junk after all.

An AI leader wouldn’t make mistakes like humans, thus, it would do everything the same way, and incrementally get better but only to a point without any real creative input, or recovery from a future mistake, wow, this topic is getting more philosophical than scientific, so I will leave you with these thoughts to ponder. Be Great!

 

Last Minute Checks Before Deploying Your Website

sAs a developer myself, I am fully aware that it is all too easy to miss something before concluding that a bug is fixed. To help prevent, or at least reduce some regression errors from occurring, I have put together this checklist which can be used to run through as a final sanity check before releasing the change to a production environment.

Different Web Browsers.

Today there are many different web browsers which are used to view web pages. Each one interprets the HTML in mostly the same way, but there are subtle differences. The HTML standard has evolved in parallel to the web browsers, making it a challenging task for the browser developer companies to keep up. This has lead to some browsers not supporting all features. It is important for a web developer to keep track of the most used browsers and know which versions are used by their end users. The most common browsers today are Chrome, Internet Explorer versions 9 to 11, Firefox, Safari and Opera. It is a safe bet to support at least the first three of these to guarantee the robustness of the website .

Different User Types.

A web application may be used in different ways by separate groups of people. For example, for an eCommerce website like Amazon, most users are visiting the site to browse for products. There are also sellers who have access to manage their own products. There will also be several groups of users within Amazon’s own staff such as warehouse operatives, statistics analysts, site administrators and system administrators. Each type of user will have access to different areas of the software so it is important to check features by logging in as each type of user.

Form Validation.

This is the process of checking that a form has been completed with the minimum required set of fields as well as checking that all completed fields have valid data entered into them.

Examples of invalid data include incorrectly formatted dates, letters or symbols in number-only fields, too much text entered into a field.

Mandatory fields should be clearly marked, usually with a red asterisk.

If a field is invalid then it should be highlighted in a suitable colour so the user can easily locate it and correct it.

Page Navigation.

Every page should have suitable links or buttons so that the user does not feel lost. They should be able to know how to get to the next page, return to the last page they viewed and go back to the main home page. Page navigation can either be done by adding Home, Previous and Next buttons, or my implementing a breadcrumb trail.

A breadcrumb trail is a sequence of links to pages which lead from the home page to the currently viewed page.

Database Operations.

A web application with a backend database will have different permissions to view, add, modify and delete data. This is sometimes referred to as CRUD (Create,Read,Update,Delete). These operations will be linked to specific user types.

The majority of users will have minimal access to view site content, usually the general public. The next level will be junior staff who can update some of the site content. Then more senior staff will be able to add fresh content and remove old content.

All these operations should be checked to make sure database permissions have been configured correctly. Check that data from a database is loaded without errors, make sure it can be modified and saved back to the database. Then try adding fresh content and deleting it. Different levels of access may be required to test all four operations.

User Maintenance Features.

If a web application has the ability for users to register and login then there should be a page where user accounts can be maintained. Passwords will need to be resets, email addresses updated as well as other personal details.

Some applications may allow a user to update their own details, in which case this should be done securely since sensitive data will be updated external to the firewall. This is less of a concern if user maintenance is done my site administrators, although it is still a good habit to implement good security in case the system is breached.

Security Aspects.

If your web application is being deployed on the Internet then it is crucial to perform a few basic checks to make sure that hackers cannot hijack your application and exploit it for their own endeavours. Penetration testers will perform more detailed checks, but it is worth doing the following checks for your own peace of mind.

Hackers will look to exploit any point of entry in your application which include forms, text areas, URLs and any unhandled errors.

SQL injection

This is the process of attempting to modify a database query by appending malicious text in text boxes or the URL address bar. The usual technique is to add a single quote character before and SQL ‘logical AND’ condition which will force the database to return more data rows.

On a login page, this technique could be used in the username or password boxes to override the login check and gain access to the application, potentially making all secure pages accessible to the hacker.

For example, if the text ‘OR 1=1’ is inserted into a password field, the login check query could be modified like this:

select username, password from tblUsers

where username = ‘user123’ and password=” OR 1=1

Cross-site scripting (XSS).

This is the process where JavaScript code can be pasted within a

Then navigate to a page which reloads this data. If an alert box pops us, you have discovered an XSS vulnerability.

Luckily, XSS attacks can be prevented by either removing tags from and text control or, if HTML is allowed, then it could be escaped to prevent it from being executed.

Cross-site forgery

Login forms are naturally built to be extremely secure since they are the front door to an entire website . However, this does not necessarily stop hackers from mimicking the login request sent to the server.
How does the server recognise that a request has come from the correct web application? Anyone can view the HTML source to determine the form fields sent to the server. A hacker could therefore generate login requests to attempt access using sequentially-generated login credentials.

The solution to cross-site forgery is to include a token as a form field which is encrypted using a secret key on the server. When the form is submitted, the token will be checked to guarantee that the request is genuine and authentic.

Overall Performance.

As you use the web application, do you notice that some actions appear to be taking too long to complete?

Are there lots of timeout errors being produced by the server?

There may be a database query which is returning too much or unnecessary data. Some code could be included in a loop where it should only be executed once. Perhaps there is a problem with the server configuration?

Of course, the development environment may need a memory or processor upgrade to reduce sluggishness, but it is always good to eliminate the software first. If the environment is naturally sluggish for other applications, use this as the benchmark to assess whether the source code can be improved.

No JavaScript Functionality.

These days JavaScript is switched on for the majority of users. Some web applications may even disable the login screen if JavaScript is not enabled. However, if a website needs to be accessible to people with visual impairments then it will need to provide some kind of Functionality without JavaScript.

Screen readers parse a web page to read out the text to the user. Links and buttons will need to be activated via the ‘tab’ key or invoked by a ‘hot key’ sequence. Any JavaScript in the page will be ignored and could hinder or confuse the user’s understanding of the page.

Turn off JavaScript in your web browser and see how each page is displayed. Are all controls accessible without using the mouse?

User Accessibility.

Any web application should be accessible to as many people as possible. Some may only be targeted at technical users who don’t require much guidance or instruction, whereas others will need to be designed to be used by less computer-literate or people with learning disabilities.

It is best to design an application to be accessible to the least computer-literate, or at least allow features to be customised by the user.

Here are some guidelines to make sure your application is accessible:-

  • Be able to control overall text size.
  • Clear contrast between background/foreground colours. Black on white or vice versa is the ideal.
  • Links and buttons should have keyboard shortcuts.
  • Clear images with alternate text specified for screen readers.
  • Suitable line spacing to match font size and avoid cluttered paragraphs.
  • Form labels matching with fields.
  • Clear navigation links – Home and Back buttons, pagination, breadcrumb trails.
  • A good consistent heading structure.
  • Avoid sole use of colours to highlight information. Colour-blindness is very common.
  • Different Devices or Screen Sizes.

Nowadays, people don’t just use a computer to view web pages. Your website could be viewed on phones, tablets, large TV screens or even watches.

Some website s may be designed for mobile-first, others may be designed for the most common 800×600 or 1024×768 resolutions. Web browsers on smaller devices will often zoom out to show all content on a page so it is up to the user to pinch/zoom to the content they desire.

A truly responsive application should collapse large areas to display vertically, resize fonts or images appropriately, increase size of buttons for fat fingers or omit areas to reduce clutter on a smaller screen.

Some pages may provide the option to print on a printer or download as a PDF. Menus, navigation links and banners are redundant for printers so these areas should be excluded. Image and font size may need to be adjusted to show clearly on an A4 page as opposed to the screen.

Different Languages.

If the language of the application can be changed to suit users from different countries, then it is a good idea to scan through the content in each language. Non-English languages use character sets which may contain accented characters.

The web page will need to recognise the character set to avoid garbage characters being displayed. If the content is returned from a database, then the database column will also need to be configured to recognise the character set.

Does it work from fresh?

Remove all data and users and start using the application from fresh.

As an application is developed, configuration data can be pre-populated manually so it is assumed that it is always available. Then the software is installed in the production environment and it fails because the data cannot be found.

Site-wide Error Handlers.

It is impossible to locate all bugs in any software application, but when a bug is found by a user, you do not want the server to show them an error dump which may reveal source code or clues to the server infrastructure. This information would be invaluable to a hacker intent on devising a method to break your server.

The protection for this is to create a page to be invoked whenever an error is encountered. A general server error in an existing page is assigned a status code of 500. If a page cannot be located on the server, a status code of 404 is assigned.

A page to handle each status code should be created so that the user will see an informative screen saying that “something has gone wrong” or “the page could not be found”. The page will then email the error diagnostics to the system administrators or developers so that the bug can be logged and resolved.

Consistent Look and Feel?

Navigate through the pages of your web application and look for any irregularities in how each page is display.

Content text should be in the same font and alignment throughout the site. Likewise, all buttons and links should be styled in the same way, unless there is an obvious reason to deviate. Each page should have the correct navigation links and appropriate breadcrumb trail. Make sure that the banner, sidebars and footer are included on each applicable page.

If a single page is different from the rest, then it will look odd and stand out to the end user. They may also become stuck a page if there are no links to ‘break’ out of the loop.

Why Do We Use Django For Python

3fDjango can be defined as a high-level Python Framework that helps the users to come up with faster as well as cleaner development along with some realistic designing of websites. Developers today prefer to use Django over Ruby on Rails due to certain reasons. They are described below:

Language

Python is extremely articulated as a language. You will find definite guidelines along with instructions, particularly about the way the codes are to be written or formatted. Besides, you will also find a clean structure in the codes, irrespective of whatever you do. In fact, the framework follows the good old principle that says, “Codes are more read than they are written.”

Presence of 3rd party Libraries

When it comes to 3rd party libraries, using Python will not pose any problem for the developer. The libraries are powerful as well as mature enough to make coding seamless as well as fast as well as free of hiccups.

Helper Tools

It comes up with some helper tools that will make the life of the developers much easier. These tools help you maintain as well as deploy the codes.

In other words, one framework is used over another because of the advantages it is offering. From that point of view, Django scores over Ruby in a number of aspects.

In fact Django is the framework for those who are perfectionists, particularly those, who tend to work with strict deadlines. With a string of value added features like helpers, working ORM, a fantastic admin interface as well as a few more, Django is a developer’s dream framework.

Object-Relational Mapper

It comes up with a default implementation mechanism that helps the developers when it comes to writing databases as Python class and query the same databases by using Python. This means that there is no need to write even a single SQL line manually.

Admin Interface

When it comes to taking care of a specific website or a client, it is imperative to manage all the content in a competent and flawless way. However, that does not mean that the codes and other texts need to be written in order to save time. It saves a lot of time as well as work. Django does exactly that.

It is a good tool and a well built one as well and this makes quite a difference at the end of the day.

Guarantee the longevity of the site

This is another cool factor that will speak for Django. The framework helps the sites to enjoy longevity. It means the site will not go down easily. That it ensures better life expectancy of the site is one of the major reasons why sites today are made up more with Django than anything else.

It is fast

Each and every bit of this framework is designed keeping in mind the speed factor. The template language of Django is much faster. The speed is so fast that even the caching compiled templates appears slower than when it comes to re-rendering them upon each and every request.

Django Scales

Whatever you do – right from launching and running personal websites that run on shared hosting to the small band websites and the huge databases of public information to the social networking sites, Django is ultimate when it comes to handling all the data successfully. Hence, the Django development framework features some astounding scalability that makes a difference. On top of everything, the budget involved is truly realistic as well as manageable.

 

Best Practices in Web Application Testing

weWith more and more users accessing websites on their smartphones, tablets and phablets, it has become essential for businesses to optimize their web applications for mobile devices. At the same time, each business needs to test the web application thoroughly to ensure that it delivers richer user experience across many browsers and under various conditions. While testing modern web applications, QA professionals have to address challenges related to integration, interoperability, performance, usability and security. So the QA professionals must follow simple best practices to test the web applications more effectively.

7 Best Practices for Web Application Testing

1) Focus on Cross-Browser Compatibility Testing

Nowadays most businesses opt for responsive web design to make their web applications deliver richer user experience on each device. The new approach requires programmers to make websites responsive by using open web technologies like HTML5, CSS3, and JavaScript. At present, older versions of certain web browsers do not support HTML5 fully. So the testers need to check how the app performs on both older and current versions of major web browsers. They can even use specialized automation tools to test the application across many browsers quickly and efficiently.

2) Test Each Important Element of a Web Application

While testing a web application, QA professionals often focus on its features, functionality and performance. But a business must ask the testers to assess each important element of the website in addition to its functionality and performance. For instance, the QA professionals must assess key elements of the web application including cookies, CSS, JavaScript, HTML validity, dead-links, browser refresh, windows resizing, and security. The comprehensive testing will make the website deliver richer user experience over a longer period of time.

3) Assess the Application’s Performance under Various Conditions

In addition to assessing the stability of the website’s functionality, the testers also need to ensure that it does not crash under heavy load. Sometimes minor flaws in its design or code also affect the website’s performance negatively. So the testers must assess the performance of the application under a variety of loads to check how it caters to a large number of visitors. They can even use open source load testing tools to assess the performance of the application under varying load on the server effectively. Likewise, they must perform load testing repeatedly to ensure that the performance of the website is not impacted by the changes made to the code.

4) Scale the Load Tests Incrementally

In addition to assessing the performance of the website under varying loads, it is also important for the QA professionals to scale the load tests incrementally. In the initial stages, they should replicate a comparatively smaller number of distribute user, and increase the number of users gradually. When the number of users increases gradually, it becomes easier for software testers to identify the exact point where the application crashes. However, the QA professional must perform load tests in cycles and analyze the load testing result of each cycle to assess the performance of the website accurately.

5) Don’t Forget to Check HTTP Traffic

While testing a web application, businesses often forget the significance of analyzing the web traffic. When the testers check the HTTP traffic thoroughly from the browsers to the server, it becomes easier for them to assess each request and response precisely. At the same time, the HTTP traffic analysis helps them to test Google Analytics tags and similar third-party tracking tags used by the web page. The testers can further use specialized tools to ensure that each tracking tag includes correct values, and the third-party systems respond to the user requests quickly and properly.

6) Test the Web Services Independently

Nowadays most web applications use a variety of web services. But the business needs to ensure that the web services used by the application are tested independently, and as isolated components. The testers must test the web services before they are integrated with the application. The option will enable them to test the web services more quickly, while exercising better control over their functionality. Also, the testers can send a variety of request to the web browser directly and assess its performance without using a web browser.

7) Pick the Right Parameters for Usability Testing

The business must focus on both usability and user-experience of the web applications to keep the visitors engaged and convert them into customers. However, it is also important for the testers to assess the usability of the applications based on the most appropriate parameters. The business must clearly define the key criterions for performing usability testing. At the same time, the business also needs to pick a number of key criterions like user interface design, speed, performance, readability of content, accessibility and navigability. Likewise, it must ask the testers to determine the amount of time required by a user to perform specific tasks.

A business can always automate its testing efforts to quickly check the look, feel, usability and performance of the web application across many web browsers. However, it also needs to focus on development, maintenance and reusability of automated tests to test the frequently changing front-end of the web application more effectively.

 

Importance of Back-End Web Development

4gWhile creating a new website, developers have to focus on both frontend and backend development. The frontend of an application refers to the code that is visible to the website visitors. Normally, frontend code creates interfaces through which the application interacts with the users. On the other hand, the backend code interacts with the server, and delivers content or data to be displayed to the users. So the backend code deals with the application as well as the web server and database. The combination of application, server and database makes the backend coding both complex and important.

Why Developers Must Pay More Attention to Backend Web Development?

Facilitates Information Exchange

As noted earlier, backend consists of three key elements of a website, i.e., application, web server and database. While accessing the user interface of a website, each user is required to provide his login id and password. The login id and password provided by the user is validated by the backend. Likewise, any information submitted by the user is stored in the databases through the backend code. Also, the backend retrieves information from the database, and sends the information to the user interface for displaying to the user. Hence, the backend of a website acts as its structure and facilitate information exchange.

Runs in Various Environments

Nowadays, businesses deploy websites and web applications in a number of environments. For instance, some enterprises prefer running websites on web servers, while others deploy web applications in the cloud. At the same time, many businesses even combine both hosting options to avail benefits like enhanced performance and scalability. The web server setup varies from one network to another. Also, the programmers often distribute server-side workload over multiple machines. The varying hosting environments make it essential for developers to customize the backend of websites.

Contains the Application Logic

Most programmers nowadays keep the user interface and application logic of a website separate to simplify its development and maintenance. In addition to including the domain and infrastructure components of an application, the application logic also performs the routine data processing required by each business. The backend of a website contains its application logic. Hence, the developers must focus on backend web development to switch from one frontend to another seamlessly, and make multiple user interfaces access the same application logic.

Adds Utility to Each Frontend Functionality

While developing a website, programmers are required to write backend code to add utility to each frontend functionality. For instance, they have to write code using a server-side programming language to add functionality to a user login form. Each time a user enters his login credentials, the backend code will collect the values, and compare them with the login data stored in databases. Likewise, backend code also adds functionality to various forms, profiles and accounts. Hence, no website can function without quality backend code.

Impacts the Website’s User Experience

The usability and user experience of a website impacts its popularity in the longer run. As noted earlier, all tasks required to make a website function are performed at the backend. So the user experience delivered by a website will be impacted by the quality of backend code. Any issues in the backend code can result in frequent website crashes, running the website slowly, and similar performance issues. At the same time, minor defects in the backend code can make the website vulnerable to targeted malware and security attacks. It is important for the developers to focus on the quality and structure of the backend code to make the website deliver richer user experience without any interruptions.
