Component Selection for Component Based Software Engineering

Abstract

Component selection is not an easy task in Component Based Software Engineering .and it is very difficult to select component for CBSE. Component Based Software Engineering (CBSE) is a concerned with the assembly of pre-existing software components that leads to a software system that responds to client-specific requirements. This paper presents an approach for defining evaluation criteria for reusable software components. We introduce taxonomy of factors that influence selection, describe each of them, and present a hierarchical decomposition method for deriving reuse goals from factors and formulating the goals into an evaluation criteria hierarchy. It also presents a summary of the common problems in reusable off-the-shelf software selection, describes the method .It also indicates that the evaluated aspects of the method are feasible, improve the quality and efficiency of reusable software selection. In this paper the selection of component is done on the basis of the cost of the component which is calculated on the basis of the quality attributes of the component. The approach used for selecting the component is a part of OTSO method that has been developed for reusable component selection process.

New Algorithm for Component Selection to Develop Component-Based Software with X Model

“…Researchers and practitioners generally use the simple component selection problem and criteria based component selection problems. [7]- [9] A. Simple Component Selection Problem Simple Component Selection Problem (SCSP) is the problem of choosing a number of components from a set of components such that their composition satisfies a set of objectives [7], [8].…”

“…The goal is to find a set of components Sol in such a way that to every requirement rj from the set SR can be assigned a component ci from Sol where rj is in SRci, while minimizing the number of components in the solution Sol and/or while minimizing ci € Sol cost (ci). Another criterion for selection of components in CCSP is dependencies involved between the components [7], [8].…”

An Evaluation on Various Software Component based Selection Techniques

“…Merging modules is less time consuming as compared to implimentation of each module. CBSE institutes philosophy of obtaining rather than build [2] . For eg: if we want to create a car engine, then instead of creating each hardware, we just use the hardware which was created earlier.…”

Optimal Performance Model Investigation in Component-Based Software Engineering (CBSE)

“…COTS-based systems development requires specific activity like desire component selection, composition and last but not least the most important is component integration. After the successful working of this technique it became more popular as a result of this today a large number of software components are commercially available, components selection a to fulfill the all system requirements which minimize the cost of the system software [21]. In COTS for large system are become common a days.…”
