What is a web application?

14 June 2021 | Blog

A web application (or web app) is a computer program that is stored on a remote server and accessed using an internet browser.

How do web applications work?

Web apps use a combination of server-side scripts to handle the storage and retrieval of information, and client-side scripts to present information to users.

In order to operate, web apps need a web server, application server and database. These are the components that work as a collective to make them run. If businesses have certain requests for their web apps, the developers can manage them through the web servers. The application server is the component that carries out the task as requested. The database, on the other hand, is where back-end information is stored and retrieved whenever needed.

The demand for web apps has increased due to their capabilities and flexibility. They are also popular as they do not need to be downloaded, instead they are easily accessible using an internet browser.  If a user wishes to access the web app, they simply need to type the URL and they can start using it through the web browser as long as they have an internet connection.

Examples of web apps

Web apps can be designed for a range of purposes, common examples include:

  • Online form
  • E-commerce solutions
  • Word processors
  • Spreadsheets
  • Video and photo editing
  • Online calculators
  • Email programs
  • File conversion
  • File scanning

The most widely used web applications include Google Drive and Microsoft 365.

Web apps can be used by businesses to facilitate better communication between employees, allowing them to easily create documents and collaborate from any locations and using any device. They can also be used to offer a wider range of services to customers in an effective, user-friendly manner.

What is the difference between a website and a web app?

As we are sure you are aware, a website is a group of linked web pages, accessible globally.

Web apps are extremely customisable websites which can deliver a wide range of functions and interactive elements to allow a two-way information flow. They are responsive and will adapt to whatever device you are viewing them on.

Both a website and a web application are accessed through a web browser but a web application is often connected to a database so data can be collected, stored and referenced.

What is the difference between a mobile app and a web app?

Native mobile apps are built for a specific platform – iOS or android. They are downloaded and installed via an app store and then remain on the device then have been installed on. They often need permission granted so they can access functions of the device.

Web apps are usually built using JavaScript, CSS and HTML5, like a web page. They are accessed using a web browser and do not need to be downloaded or installed. Web apps tend to be quicker and easier to build than mobile apps.

What are the benefits of a web application?

Maintaining an online presence is vital for most businesses, and utilising the latest technology helps to gain competitive advantage. Web applications help with this while also delivering many other great benefits:

  • Users only need internet access and a web browser
  • Can be accessed from anywhere, using any device – desktop or mobile
  • Interactive and encourage users to engage with your business
  • Responsive to deliver excellent user experience
  • Quicker and easier to develop than mobile apps
  • Do not need to be downloaded or installed
  • Do not require app store approval (unlike mobile apps)
  • Hosted on a remote server so do not take up storage space
  • Easy to maintain

In order to provide the benefits that every business deserves, web applications have to be combined with a dynamic website and software that users can access over the internet to bring about certain functionalities such as improve online user interaction, maintaining a back-end connection of the database and generate the needed results in web browsers.

Is a web application right for your business?

If you want to interact with customers online, customised web applications allow you to carry out tasks that will boost online presence and allow customers to make a smooth and easy transaction. The recent growth and reliance on e-commerce further solidifies the need for web app development as they play a vital role in channelling purchases made online. Some other things to consider are:

  • Do you want to centralise the operations of your departments and improve your proceedings, project management, sales and more?
  • Do you want to take advantage of a modern solution that will allow your company to offer an online-based platform as an enhancement of your existing traditional desktop application?
  • Do you want to offer a better service to your clients by offering a safe and easy way to make purchases online or gain more clients?
  • Do you want to build new business solutions that will make your clients happy and your business more consolidated?
  • Do you want to facilitate better communication between your staff, regardless of their location?
