Tool for calculating reusability of object oriented programs

Software reuse increases the productivity and reduces the cost and improves the Quality of the software development. Reusability is one of the most important quality characteristic. Therefore it is necessary to measure the reusability of the module in order to realize the reuse of module effectively. By reuse the module of existing software has increased in past recent year which impact more on the software quality. Many measuring reusability methods have been propose for estimating the reusability of module. If any software system using the reusable component from existing System it save the lot of time for developing the software and also cost of the software development. It also increases the performance of the software and aim of the any software organization is giving the product with good quality and low cost as soon as possible. If we reuse the oldest module which is already develop in new system it increase the productivity because effort of the programmer is reduce and it correctness is also increase because exist system already tested. Problem is that which module or component is more suitable in oldest software for reuse. In this thesis we developing the tool which is calculating the reusability for the object oriented program and display existing module is acceptable for reuse or not.
