The demands of software engineering increases with everyday passed and every organization shows interest to work on daily routine work in the computerized system to improve efficiency and accuracy of data. Most of organization demands different kinds of computerized software solutions that developed in modern technologies. There are different software development technologies that is getting popular with the passage of time and provide high quality product to their user. It is not an easy to decide which technology choose to develop computerized system where most software falls. The primary purpose of thesis is to compare two different modern software development technologies by develop an application with same functional requirements. This thesis report will help to user for selection of software development technology. Cash and bank financial application is choose to develop using .NET and Java Enterprise Edition. Microsoft Visual Studio development environment is used for .NET development and NetBeans IDE is used for Java Enterprise Edition application. .NET framework contains many language that are interrelated with each other like C#, VB, J#, C++ and F#. Cash and bank application is develop in C# and Java programming languages and persistence storage of data is design in Microsoft SQL Server. Cash and bank application is develop with three tier architecture and layer approach. The syntax of .NET and Java Enterprise Edition is quite similar but procedure to establish connection, data retrieval and handling the data in different way. NET platform provide built in libraries, components and efficient user controls that helps for fast development in short period of time.
