Clustering Software Components for Program Restructuring and Component Reuse Using Hybrid XNOR Similarity Function

AbstractComponent based software development has gained a lot of practical importance in the field of software engineering from academic researchers and also from industry perspective. Finding components for efficient software reuse is one of the important problems aimed by researchers. Clustering reduces the search space of components by grouping similar entities together thus ensuring reduced time complexity as it reduces the search time for component retrieval. In this research, we instigate a generalized approach for clustering a given set of documents or software components by defining a similarity function called hybrid XNOR function to find degree of similarity between two document sets or software components. A similarity matrix is obtained for a given set of documents or components by applying hybrid XNOR function. We define and design the algorithm for component or document clustering which has the input as similarity matrix and output being set of clusters. The output is a set of highly cohesive pattern groups or components

Software Reusable Components With Repository System

Software reuse is the process of creating software systems from existing software rather than building them from scratch. The goal is the use of reusable components as building blocks in new systems with modifications occurring in a controlled way. The reuse of software components is the key to improve productivity and quality levels in software engineering. One of the most promising approaches to reduce costs and improve reliability is component-based development, which aims to allow new applications to be assembled from prefabricated parts rather than coded from scratch. Software reuse involves building software that is reusable by design and building with reusable software. Software reuse includes reusing both the products of previous software projects and the processes deployed to produce them, leading to a wide spectrum of reuse approaches, from the building blocks (reusing products) approach, on one hand to the generative or reusable processor (reusing processes), on the other
