In terms of computing, a web application can be defined as a client-server computer program that the client runs in a web browser. Some typical web applications include online banking, online retail sales, webmail as well as online action. The websites that are most likely to be described as web applications are basically the ones that have similar functionality to the desktop software application or to a mobile app. There is not much clarity about the distinction between the web application or any dynamic webpage. HTML5 introduced explicit language support for making the applications that are loaded as web pages. Although they can store data locally and continue to function while offline. Single-page applications are much more application-like because they can reject the more typical web paradigm of moving between distinct pages with different URLs.
Writing web applications are generally simplified by the use of a web application framework. Such frameworks facilitate rapid application development by allowing a developing team to focus on the parts of their application that are unique to their goals without having to resolve the common development issues like user management. Many of the frameworks in use are typically open-source software. The number of errors in a program can gradually be reduced by the use of a web application framework. This task is performed by making the codes more straightforward and by allowing one team to concentrate on the structure while another focuses on a specified use case.
In Business Use
Application software companies find an emerging strategy in providing web access to the software that is previously distributed as local applications. Depending upon the type of application, the development of an entirely different browser-based interface is or adapting an existing application to use multiple presentation technologies. These programs allow the user to pay a monthly or yearly fee for using the software application without installing it on a local hard drive. A company that follows this strategy is known as the application service provider and ASPs are currently receiving considerable attention in the software industry.
There are significant concerns about security breaches in this kind of application as it involves both enterprise information and private customer data. Protecting such assets are very important for any form of web application and there are some crucial operational areas that should be included in the development process. This consists of the processes for authorization, asset handling, authentication, input as well as logging and auditing.
Benefits of web applications for businesses.
- Improved Efficiency-Having multiple versions of spreadsheets or shuffling around piles of paperwork is not only time consuming, but can also leave your business vulnerable to human errors that are not easily spotted until it’s too late. With no integration between these multiple sources of data, time-consuming and laborious replication of data may be required in order to get a holistic overview of business performance. Web applications help you streamline your business processes so that you can get more done in less time and with greater accuracy. What’s more, having all your data integrated in one place gives you greater visibility of your business, freeing up staff time and allowing you to run reports that are updated with real-time information.
- Accessibility- Given that business systems created by web applications are web-based, they can be accessed 24/7 provided that you have an internet connection. What’s more, they are totally flexible, offering access from almost any device or browser. When desktop-based software needs updating, every single device in which the application is installed will need individually updating. This task usually falls to staff and may be ignored if they are pushed for time, leaving your business vulnerable to security breaches. Compare this with a web-based application, where a security or functionality update can be rolled out to every version of the web application with zero downtime, giving users instant access to the updated version of the app.
- High level security-With desktop-based software, a stolen or damaged computer can be a very costly and time-consuming situation; leaving your data at risk and requiring you to contact your software provider and request for the software to be re-installed on a new device. With a web-based application (with data stored in the cloud), you have the peace of that should your computer equipment be damaged or stolen, it can very quickly be back to business as usual. This is because web applications store information on remote service, so as long as you know your URL, username and password, you can log-in securely to any computer or mobile device connected to the internet and your business can be up and running again in no time.
So with all this information it is evident that to take your courier service to the next level you will need web applications.
