Component based applications a technique for design

Abstract

In the field of Software Engineering, Component-based development (CBD) has become a much talked-about subject: today. While the technology of CBD, as demonstrated by environments such as COM and EJB, has developed increasingly, this has not been complemented by corresponding maturity on the methodology front. Of the few published methodologies available for the design of components, most address the process of building systems from a set of pre-built components. However, an important scenario that is left un~addressed is that of the design of custom applications, With most of the companies going for custom applications it becomes very important to address this. In such contexts, the CBD design question involves the creation of business components from a set of software requirements. As per my knowledge, currently there is no published prescription that addressed this need, At best, practitioners rely on published collections of software patterns or heuristic and unproven guidelines such as those advocating correct component granularity. This is a work on a design methodology for identifying two classes of business components based on an object-oriented specification of requirements. These are entity components and process components. The project includes work on a methodology, uses examples to illustrate, and also includes a ease study. The application of this technique has also been discussed, Challenges associated with reuse of components and their impacts have been mentioned
