  1. Component-Based Software Engineering(CBSE) Xingui Tang CS532, Fall 2003 7/16/2014

  2. Content • Introduction • Component • Software component • Component-based Software engineering • Component-based software construction • Typical CBD Process Model • Introducing and Establishing CBSE from an Organizational View • Three phases • Requirements • Pros and cons of CBSE • Conclusion • Reference

  3. Introduction • Component

  4. Introduction----Cont. • Component A component is a nontrivial, nearly independent, and replaceable part of a system that fulfills a clear function in the context of a well-defined architecture. It conforms to and provides the physical realization of a set of interfaces. --- Philippe Krutchen

  5. Introduction----Cont. • Software component • Definition • A software component is a unit of composition with contractually specified interfaces and context dependencies only. It can be deployed independently and is subject to composition by third parties. ---Clement Szyperski • A software component is a software element that confirms to a component model and can be independently deployed and composed without modification according to a composition standard. ---Bill Councill and George T. Herneman

  6. Introduction----Cont. • Software component • Feature • Identity • Modularity and encapsulation • Contact-based interface • Independent deliverability • Reusability • Interoperability • Deployability

  7. Introduction----Cont. • Component-based Software engineering • Definition Component-based Software engineering denotes the process of building the software by (re)using pre-built software components thus basing on the meaning of software components. CBSE is also referred to as component based software development (CBSD) or component-based development (CBD).

  8. Introduction----Cont. • Component-based Software engineering • Why need it • software exists problems • SW is late • SW is buggy • SW is expensive • SW is difficult to understand • SW is difficult to maintain • CBSE can solve the problems • Focuses on reuse of subsystem and infrastructure

  9. Component-based software construction Type 1

  10. Component-based software construction----Cont. Type 2

  11. Component-based software construction----Cont. Type 3

  12. Typical CBD Process Model

  13. Introducing and Establishing CBSE from an Organizational View • Three phases

  14. Introducing and Establishing CBSE from an Organizational View----Cont. • Requirements • CBSE approach must include • reuse component selection • component test • requirements reconciliation • CBSE must be supported by • modeling formalisms and tools • development tools

  15. Pros and cons of CBSE • Pros • Increased Reliability • Reduced Costs and Development time • Promotes Software Reuse • Reduced Maintenance Costs • Cons • Lack of world wide standards • Lake of flexibility in the system design • Hard to meet the demands of high reliability and availability • Requires skilled people

  16. Conclusion • Promising • Challenging
