Question

(a) Component-based Software Engineering (CBSE) is an approach that reuses the software component to develop software. CBSE can be represented as a process of identifying, performing and integrating loose components into systems.
Discuss the problems with CBSE.

Answer 1

The components in CBSE can be any units of reuse and integration, which can be computational (i.e., functional) components, interface components,communication components etc. But to maximize the productivity gain and cost reduction, CBSE must be based on domain-oriented components as well as generic components

1.

Productivity will be higher for Domain Oriented Components. But in immature and unstable domains, there may not be much domain-oriented components to reuse. So, CBSE can be applied only in mature and stable application domains, or in an organization where a family of closely related products is produced like oracle.

2.
While developing an application by integrating components, there must be components that can
solve the problems of the given application. Therefore, CBSE must address not only the
issues of how to integrate components but also the issues of how to produce integratable
components.  

3.
The cost involved in producing reusable components. The cost of producing reusable components is substantially higher than the cost of producing a single application without reuse consideration, as high as five times
the cost of producing a single application.

4.

Developing a software for future reuse is not an easy task in software development for cooperates, as they are based on projects. Issues like platform migration will arise, which should inturn make sure of the compatability of the components that are being reused.
