Businesses are becoming automated nowadays, with almost every business getting an online representation in the form of Web Application. The different kinds of businesses require dynamic nature of Web Applications which require less dependency on a human controlled software interface. With the applications catering to the needs of hundreds to thousands of users simultaneously, it’s hard to manage such kind of applications using a combination of human interface. This particular need has led to the study and research in the field of software agents or intelligent agents, which use some kind of intelligence to aid the various operations of the application in use. Several studies and research has been made in this area which has resulted into development of some high quality software applications over the web, which boast to have complete functionality driven by these intelligent agents and require minimum to no human interference. In this research work, software modelling of Web applications using intelligent agents has been envisaged. The various fundamentals of agent research has been discussed in detail with special heed to implementation framework. Finally, an agent based model has been developed using the latest tools and techniques. This research work provides comprehensive analysis and implementation of an agent based software application.
