Component Based Software Engineering

Abstract

Traditional software estimation models are directed towards large monolithic software development projects. Contemporary software development practices require a new approach to software cost estimation. Contemporary development practices characterize a software application as interacting, independent components. Component-based development offers many potential benefits such as a greater reuse. Component based software development approach is based on the idea to develop software systems by selecting appropriate off-the shelf components and then to assemble them with a welldefined software architecture. Software community faces a major challenge that is raised by fast growing demand for rapid and cost-effective development and maintenance of large scale and complex software systems. To overcome the challenge, the new trend is to adopt component based software engineering (CBSE).The key difference between CBSE and traditional software engineering is that CBSE views a software system as a set of off-the-shelf components integrated within appropriate software architecture. CBSE promotes large-scale reuse, as it focuses on building software on building software systems by assembling off-the-shelf components rather than implementing the entire system from scratch. CBSE also emphasis on selection and creation of software architecture that allow systems to achieve their quality requirements .As a result, CBSE has introduced fundamental changes in software development and maintenance.

A Component-Based Middleware for a Reliable Distributed and Reconfigurable Spacecraft Onboard Computer

“…CBSE covers not only the software architecture, modular software design, configuration, and deployment. It also considers software verification [35]. From an efficiency point of view, tests and verifications of components can be decoupled and reused with little or even without modifications.…”

Evaluating Trustworthiness of Software Component

“…In CBSE, a software product are built as an assembly of software components already developed and prepared for integration. The main advantages of the this approach include increased productivity, effective management of complexity, a wider range of usability and extendibility, a greater degree of consistency, and reduced time to market (Kaur & Mann, 2010).…”

ALMM Solver: The Idea and the Architecture

“…-Reliability -the SimOpt module is designed using the component architecture [32], [29], [28], [33], [37]. This allowed us to reduce the software regression [36] during the development of the framework.…”
