CASE stands for Computer Aided Software Engineering and refers to the development and maintenance of software projects using various software tools to increase speed and handle changing market demands. There are classic CASE tools like debuggers and compilers as well as real CASE tools that support multiple phases of development from analysis and design to coding. Real CASE tools include diagramming, process modeling, project management, documentation, analysis, design, configuration management, change control, programming, prototyping, web development, quality assurance, and maintenance tools.

1.
2. CASE stands for Computer Aided Software
Engineering.
It means, development and maintenance
of software projects with help of various
software tools.
3. CASE allows for rapid development of
software because of the increasing speed of
changing market-demands new products
replace old ones much earlier than before,
so the development of new products has to
go faster.
4. Must distinguish between ‘classic’ case tools and
‘real’ case tools.
Classic CASE tools: Interactive debuggers,
compilers, project progress control systems
Real Case tools: support several phases of
development
I. Upper CASE tools support analysis and design.
II. Lower CASE tools refer to the location in these
phases in the Waterfall Model.
III. Integrated CASE tools support analysis, design,
and coding.

6. Diagram tool
These tools are used to represent system
components, data and control flow among various
software components and system structure in a
graphical form.
Process Modeling Tools
Process modeling is method to create software
process model, which is used to develop the
software.
7. Project Management Tools
These tools are used for project planning, cost
and effort estimation, project scheduling and
resource planning.
Documentation Tools
Documentation in a software project starts prior
to the software process, goes throughout all
phases of SDLC and after the completion of the
project.
