Software estimation tool based on three -layer model for software engineering metrics

In todaypsilas competitive world of software, cost estimation of software plays a major role because it determines the effort, time, quality etc. Lines of codes and function point are traditional method for estimating the various software metrics. But in todaypsilas world of object oriented programming function point calculation for C++, Java is a big challenge. We have developed a tool based on function point analysis which has three layer architecture model to calculate various software metrics project, especially for Java program. This tool has been used for estimating of various projects developed by students. Finally as a result we have shown the attributes of three layer models i.e. FP, LOC, productivity and Time etc.
