From the good old days of the tag, to the XML-savvy Web services of today, applied Internet language has come a long way. And nowhere is this more evident than in the field of Web application development.
As the Internet grew into a major player on the global economic front, so did the number of investors who were interested in its development. So, you may wonder, how does the Internet continue to play a major role in communications, media and news? The key words are: Web Application Projects.
Web applications are business strategies and policies implemented on the Web through the use of User, Business and Data services. These tools are where the future lies. In this article, I’ll take you through the essential phases in the life cycle of a Web application project, explain what options you have, and help you formulate a plan for successful Web application endeavors of your own. First, though, let’s take a brief overview of Web applications.
Who Needs Web Applications and Why?
There are many entities that require applications for the Web-one example would be Business-to-Business interaction. Many companies in the world today demand to do business with each other over secure and private networks. This process is becoming increasingly popular with a lot of overseas companies who outsource projects to each other. From the simple process of transferring funds into a bank account, to deploying a large scale Web services network that updates pricing information globally, the adoption of a Web applications infrastructure is vital for many businesses.
The Web Application Model
The Web application model, like many software development models, is constructed upon 3 tiers: User Services, Business Services and Data Services. This model breaks an application into a network of consumers and suppliers of services.
The User Service tier creates a visual gateway for the consumer to interact with the application. This can range from basic HTML and DHTML to complex COM components and Java applets.
The user services then grab business logic and procedures from the Business Services. This tier can range from Web scripting in ASP/PHP/JSP to server side programming such as TCL, CORBA and PERL, that allows the user to perform complex actions through a Web interface.
The final tier is the Data Service layer. Data services store, retrieve and update information at a high level. Databases, file systems, and writeable media are all examples of Data storage and retrieval devices. For Web applications, however, databases are most practical. Databases allow developers to store, retrieve, add to, and update categorical information in a systematic and organized fashion.
