Automation of component selection process for designing of reusable components using drag and drop mechanism

Component-Based Software Engineering (CBSE) provides a solution for the development of complex and evolved systems. When creating and maintaining these systems, repeat the task of selecting components. This paper focuses on a variety of formal software component selection techniques, both manual and automated. The main objective of this research paper is to evaluate the shortcomings of different prior art COTS component selections, whether manual, semiautomatic or automatic. Components must be identified and evaluated to determine whether they provide functionality. It has been found that each technique has its own advantages and limitations; no technique is best suited for each case. Automation is clearly superior to manual techniques because they provide a higher degree of accuracy in selecting the right components from a wider range of expected candidate components. In this article, we discuss an alternative approach to traditional component repositories that incorporates knowledge-based techniques to automatically select component sets.
