3.Computer Aided Systems Engineering

Question 1

What is Computer Aided Systems Engineering (CASE)?

Answer 1

Computer Aided Systems Engineering (CASE) is the implementation of computer assisted tools and methods in software development. CASE tools is acategory of software that automates all or part of the software development process.

Question 2

What are the main 2 categories of CASE tools?

Answer 2

1.Classic CASE tools - Mostly software development support tools.
2.Real CASE tools - These tools are used through out the SDLC.

Question 3

Based on phase CASE tools are categorized into 3. Name them.

Answer 3

1.Upper CASE (Planning, Analysis, Design)
2.Lower CASE (Implementation, Testing, Maintainance)
3.Integrated CASE (Through out SDLC)

Question 4

What are Upper Case Tools used for?

Answer 4

Upper Case Tools are used in the planning, analysis, and design stages of the software development life cycle. They support business modeling.

Question 5

What are Lower Case Tools used for?

Answer 5

Lower Case Tools are used in the implementation, testing, and maintenance stages of the software development life cycle. They do not support planning, analysis, and design.

Question 6

What is a central repository?

Answer 6

This is a shared space which shows all the information related to a project. Integrated CASE tools are mostly associated with a Central Repository.

A Central Repository is a central place of storage where product specifications, requirement documents, related reports, and diagrams are stored. It serves as a source of integrated and consistent information.
