Design, Implementation and Integration of Heterogeneous Applications

Abstract

This research paper is about integrating heterogeneous web applications using web services. A SOAP web service is being used to integrate applications like ASP.NET, Java and database. As usage of internet is expanding and the concept of web service is gaining publicity so there is a growing market demand for more cost effective and efficient heterogeneous enterprise applications. Web services opens new market to software vendors and these software vendors have an edge over other software vendors using old/traditional models. Even expensive software can be shared by many software applications as a service and hence making it more economical for customers to use it. This paper discusses about the design and implementation of database and then integration of ASP.NET application with database. Later on a SOAP web service is exposed which communicate with database and will then expose three methods to the java application. This java application is made using Servlet and JSP. The SOAP web service can now be used by any other application as per the need in future.
