Software Engineering

A Component is a tested, special purpose software unit which is reusable, adaptable, portable and interoperable. In software terms, components are also called componentware (CM).
Framework is the combination of components that can be plugged into an application.

A Software interface is the program that makes it possible for components to interact and interoperate with each other. Eg. JAVA BEANS
( DCOM is abbreviated as Distributed Component Object Model. )
Software Entities are the processes, requirements, products and resources of a software engineering landscape.

An Engineering approach to software engineering is to produce system on time and within budget.
Software Development problems are :
  1) Conceptual problem.
  2) Representation problem.

Vanilla Framework helps to bridge gap between a high level solution, to a problem and its implementation in software.
Software Requirement Specification (SRS) : This is a blueprint for the complete design of a software product.
Quality Factors : correctness, reliability, maintainability, testability, efficiency, integrity, usability, portability, interoperability, reusability.

Reusability Criterion :
Self Descriptive : this is with natural language.
Modularity : means change in one component has minimal impact on other.
Portability : means transfer of software from one system to other.
Platform Independence means it can execute on any type of platform.

Incremental Approach to software development has been formulated by watts Humphrey.
Clean Room Engineering is used to control the quality of incrementally developed software product and to certify the fitness of software products for usage at time of delivery.

CAPABILITY MATURITY MODEL (CMM) :
CMM describes software process management maturity relative to five levels
ie., Initial, Repeatable, Defined, Managed, Optimizing
      In the Initial level there is a lack of planning and the development of a clear-cut guide... [continues]
