Reengineering Of Education Institute And Coupling Measurement

This paper is based on reengineering of Education institutes in such a way that coupling risk should be less as compared to existing systems. Here, we will measure the complexity (based on coupling factor) of modules during reengineering of modules design. As we know that the coupling is one of the properties with most influence on maintenance, as it has a direct effect on maintainability. In general while any module is reengineered , one of the goals of OO software designers is to keep the coupling of system as low as possible. Classes of the system that are strongly coupled are most likely to be affected by changes and bugs from other classes. As the coupling between the classes of the system is increased, it result in increased error density. The work described in this paper measure the coupling not only through classes of the system, but also through the Packages that are included during reengineering of the module design. Coupling between packages is the manner and degree of interdependence between them. Theoretically, every package is a stand-alone unit, but in reality packages depend on many other packages as either they require services from other packages or provide services to other packages. Thus, coupling between packages cannot be completely avoided but can only be controlled. The coupling between packages is an important factor that effects the quality or other external attributes of software, e.g., reliability, maintainability, reusability, fault-tolerance etc. In this paper, some measures are proposed for measurement of coupling at the package-level in order to achieve good quality software systems. In this paper, we propose metrics for measuring the coupling between packages in a software system. Keyword Education Institute, Coupling, Package, Metrics ,System Representation and Definition Introduction Due to increasing demand of software maintenance, today reengineering techniques is one of the best choice, to full-fill the requirement of the public sector/private sector. While reengineering takes place in existing system, the complexity of modules is determined in early stage ( at design time), due to this, software designer, easily determine, about resources that is required during reengineering of any project. This paper is based on the measurement of complexity of modules, by using different types of coupling metrics, at design time. The backbone of any software system is its design. It is skeleton where the flash (code) will be supported. And while determining the complexity of the modules, here will use OO paradigm, which is very popular concepts in today’s software development environment. They are often heralded as the “silver bullet” for solving software problem.
