Component-based development is a CBSE activity that occurs in parallel with domain engineering. Using analysis and architectural design methods discussed earlier, the software team refines an architectural style that is appropriate for the analysis model created for the application to be built. Once the architecture has been established, it must be populated by components that [...]

The CBSE process encompasses two concurrent sub-processes – domain engineering and component based development. The intent of domain engineering is to identify, construct, catalog, and disseminate a set of software components that have applicability to existing and future software in a particular application domain. The overall goal is to establish mechanisms that enable software engineers [...] Components are the software units that are context independent, both in the conceptual and the technical domain. A component contain a self-contained entity that exports functionality to its environment and also imports functionality from its environment using well defined and open interfaces. Components may support their integration into the surrounding by providing mechanics such as [...] Component based software engineering (CBSE) offers inherent benefits in software quality, developer productivity, and overall system cost. And yet, many roadblocks remain to be overcome before the CBSE process model is widely used throughout the industry. The benefits of object-oriented design and component-based development seem obvious: – Reusing software saves money in the development phase [...] |
