2. What is
CASE
tools?
CASE tools are set of software application programs, which
are used to automate SDLC activities. CASE tools are used
by software project managers, analysts and engineers to
develop software system.There are number of CASE tools
available to simplify various stages of Software
Development Life Cycle such as Analysis tools, Design
tools, Project management tools, Database Management
tools, Documentation tools are to name a few.

3. Components of CASE Tools
CASE tools require a central repository, which can serve
as a source of common, integrated and consistent
information. Central repository is a central place of
storage where product specifications, requirement
documents, related reports and diagrams, other useful
information regarding management is stored. Central
repository also serves as data dictionary.
Integrated CASE tools are helpful in all the stages of
SDLC, from Requirement gathering to Testing and
documentation.
Lower Case Tools
Upper CASE tools are used in planning, analysis and
design stages of SDLC.
Lower CASE tools are used in implementation, testing
and maintenance.

4. CASE tools can be grouped
together if they have
similar functionality,
process activities and
capability of getting
integrated with other tools.
Case Tools Types
Now we briefly go through various CASE tools
Diagram tools
These tools are used to represent
system components, data and
control flow among various software
components and system structure in
a graphical form. For example, Flow
Chart Maker tool for creating state-
of-the-art flowcharts.
Process Modeling Tools
Process modeling is method to
create software process model,
which is used to develop the
software. Process modeling tools
help the managers to choose a
process model or modify it as per
the requirement of software
product. For example, EPF
Composer
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.
These tools help software
designers to design the block
structure of the software, which
may further be broken down in
smaller modules using refinement
techniques.
Design Tools

5. Case Tools Types
Analysis Tools
These tools help to gather
requirements, automatically check
for any inconsistency, inaccuracy in
the diagrams, data redundancies or
erroneous omissions. For example,
Accept 360, Accompa,
CaseComplete for requirement
analysis, Visible Analyst for total
analysis.
Configuration Management Tools
An instance of software is
released under one version.
Configuration Management tools
deal with –
Version and revision
management
Baseline configuration
management
Change control management
Programming Tools
These tools consist of
programming environments like
IDE (Integrated Development
Environment), in-built modules
library and simulation tools. These
tools provide comprehensive aid in
building software product and
include features for simulation and
testing. For example, Cscope to
search code in C, Eclipse.
Quality Assurance Tools
Quality assurance in a software organization is monitoring the engineering
process and methods adopted to develop the software product in order to
ensure conformance of quality as per organization standards. QA tools
consist of configuration and change control tools and software testing tools.
For example, SoapTest, AppsWatch, JMeter.

6. Advantages of the
CASE approach:
Comprehensive documentation
creation and maintenance is
made easier by CASE tools.
Improved
Documentation
Development cycles take less
time when certain jobs, such
testing and code generation,
are automated.
Quicker Cycles of
Development
Reusable component creation
and maintenance are frequently
facilitated by CASE tools.
Reusing
Components

7. Disadvantages of
the CASE approach:
In most cases, programmers’
productivity may fall in the
initial phase of implementation,
Many consultants offer training
and on-site services that can
be important to accelerate the
learning curve and to the
development and use of the
CASE tools.
Learning Curve:
Using a case tool is very
costly. Most firms engaged
in software development on
a small scale do not invest
in CASE tools because they
think that the benefit of
CASE is justifiable only in
the development of large
systems.
Cost:
It is important to build an
appropriate selection tool mix
to urge cost advantage CASE
integration and data integration
across all platforms is
extremely important.
Tool Mix:

8. The open-source community plays a
vital role in the development of CASE
tools, making them more accessible to
a broader audience and fostering
innovation. Open-source CASE tools
offer transparency, flexibility, and cost
savings:
Open Source
CASE Tools:
Predictive Modeling: Machine learning
can assist in predicting software
development project outcomes,
including estimates for project
completion and identifying potential
bottlenecks.
AI and machine learning are making
their mark in the world of CASE tools.
These technologies offer several
advantages, such as:
Code Analysis: AI-powered CASE tools
can analyze code, identify patterns, and
detect potential issues, helping
developers write cleaner and more
efficient code.
Artificial
Intelligence (AI)
and Machine
Learning
Integration:

9. Conclusion
In today’s software development
world, computer-aided software
engineering is a vital tool that
enables teams to produce high-
quality software quickly and
cooperatively. CASE tools will
probably become more and more
essential as technology develops
in order to satisfy the demands of
complicated software
development projects.
