Implementation of an analytical model of component based software into web based system is an important issue towards the effective software development. The mechanism towards such model implementation also enriches the quality of the model design. Formal specification would help to provide concrete and precise concept of a model. This paper has proposed a formal specification of an analytical model for a component based system, called Component-Class-Interface (CCI) which facilitates a sophisticated description of component model with mathematical explanation. A logical level implementation mechanism of such formally specified analytical model has been also implemented along with re-engineering facility. Moreover, a rule based transformation mechanism has been proposed to transform CCI into logical model. The correctness of such model transformation has been evaluated using Triple Graph Grammar. A comparative study has also been discussed to show the expressiveness of the proposed methodology. Moreover the concepts of the proposed approach have been implemented using a CASE tool.

Component-Based Software Engineering (CBSE) research is an important emerging area of Software Engineering (SE) that supports and enhances evolution of reusable components useful for creation of software solutions. CBSE has assumptions that components exist in repositories, but this is usually not the case. That is, components are in want. The aim of this work is to design and build generic software components for student management system domain using object oriented methods. Analysis of major school management system functions, data and behaviours was done. Also, pattern-based domain engineering was conducted so as to identify structure points. This led to factoring out generically reusable components. Student management system components were created for implementation using a general-purpose distributed Component-Based Software Development technology model. Consequently, a framework for implementing student management system and related systems was provided. This would contribute to the body of the emerging CBSE practices.

Component-Based Software Engineering (CBSE) is a knowledge-intensive discipline where all activities require the use and the transfer of knowledge between collaborators. A better usage, transfer and application of this knowledge are required factors to face the challenges of CBSE. In this perspective, Knowledge Management (KM) aims at setting up knowledge-focused processes in the organization. Knowledge Management Systems (KMS) are the technological infrastructure supporting these processes. In this paper, we present a new methodology of KMS implementation in a CBSE-oriented organization. We also present a case study of applying this methodology in an existing CBSE organization.
