Component-Based Development CBD has been broadly used in software development, as it enhances reusability and flexibility, and reduces the costs and risks involved in systems development. On the other hand, in order to gain a competitive edge, organizations need to define custom processes tailored to fit their specific development requirements. This has led to the emergence of process patterns and Method Engineering approaches.

So, All of authors and contributors must check their papers before submission to making assurance of following our anti-plagiarism policies. Component-based software engineering approach to software development employs the techniques of selecting reliable and reusable software components and assembling them within appropriate software architecture to form a robust software system. This approach is unique because it brings about designs that make a clear separation between the stable parts of the system from the specification of their composition. The rising need of software in 21st century is indeed of a great concern. In view of the increase in demand for software, software engineers need a proactive and pragmatic approach that will handle the situation on ground. Although object oriented approach helped in giving birth to software that reflect the object of the problem domain, the approach does not necessarily produce software architectures that can easily adapt to the changing requirements of users in this 21st century. In component-based software engineering, the software team will first establish requirements for the system to be built, the architectural design is made and detailed design omitted instead the team examines requirements to determine what subset is directly amenable to composition rather than construction.

Process Patterns for Component-Based Software Development

Component-based software enginering and software architectire is an emerging research area. It encompasses the traditional area of software design with an emphasis on the design of distributed systems. Based on the past failures of complex design techniques to gain wide spread acceptance, CBSE and software architecture languages must demonstrate that they provide significant value. A primary benefit will be the early detection of software faults. This is particularly important for distributed systems, since even simple distributed systems can be difficult to understand. LASER is exploring ways in which architectural description languages need to be designed to increase their usability, acceptability, and consequently analyzability.

The development of high quality software is the need of current technology driven world. CBSE is mainly based on the concept of reusability. Apart from these CBSE has several advantages as well as challenges which are summarized in this paper. Large and complex software development requires management of reusable components and can be selected from component repository and assembled to obtain a working application. Development of components and their assembly is different from traditional softwares which leads to the need of new development paradigms for Component Based Systems CBS. Software development life cycle SDLC provides planned and systematic arrangement of activities to be carried out to deliver high quality products within time and budget. This paper presents a comparative study of component based software development life cycle models with their strengths and weaknesses.

Emergence of Component Based Software Engineering

Component-based software engineering CBSE , also called components-based development CBD , is a branch of software engineering that emphasizes the separation of concerns with respect to the wide-ranging functionality available throughout a given software system. It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software. Software engineering practitioners regard components as part of the starting platform for service-orientation.
