Software Engineering Revision Notes for Class 11 Informatics Practices

Software Engineering
 
Software Engineering is a systematic approach to the design,development, operation, and maintenance of a software system.Software Engineering is very important for the development of software because of the following reasons:-
 
(i) Correct Specifications
(ii) Scalability Scope
(iii) Cost Control
(iv) Quality
 
Software process
 
A software process (also known as software methodology) is a set of related activities that leads to the production of the software. These activities may involve the development of the software from the scratch, or modifying an existing system.The Software processes are also known as Software Development Life Cycle(SDLC).
 
Any software process must include the following four activities:
 
1. Software specification (or requirements engineering):
2. Software design and implementation:
3. Software verification and validation:
4. Software maintenance:
 
Software Process Models
 
A software process model is a simplified representation of a software process.Each model represents a process from a specific perspective.
 
1. Waterfall model
Waterfall model was the first model proposed. It is also known as linear sequential model. In this the first phase must be completed then we can execute the next phase.No overlapping in phases is allowed in the waterfall model. It is the first model in the software development life cycle.
 
Phases of waterfall are:-
 
1)Requirement Analysis
2)System Design
3)Implementation
4)Verification orTesting
5)Deplopment and Maintenance
 
Advantages:-
 
1) This model is easy to implement and maintain
2) Each phase has specific deliverables and review process.
3) It works for small projects.
 
Disadvantages:-
 
1) Once process enters testing phase then it cannot be reverted.
2) Poor model for longprocesses.
3) High amount of risk and uncertainty
