2. WHAT IS CASE TOOLS
• CASE stands for “Computer Aided Software
Engineering”
• It is the domain of tools used to design and
implement applications
• As computer technology is being used for
automatic business and industrial application,
it is being used for automatic the development
of the software

3. REASON FOR USING CASE TOOLS
Quick installation
Time saving by reducing coding and testing time
Enrich graphical techniques and data flow
Optimum use of available information
Enhanced analysis and design development
Create and manipulate documentation
Transfer of information between tools efficiently
The speed during the system development increased

4. CASE ENVIRONMENT

5. HOW ORGANIZATION USES CASE
TOOLS
Integration becomes easy as common methodology is adopted
To facilitate single design
methodology
To improve the speed and quality of system development
Rapid application
development
Improves process through automated checking and simplified program
maintenance
Testing
Improves the quality and uniformity of documentation
Documentation
Improves by automating various activities involved in project management
Project Management
Software maintenance made easy and hence reducing the associated cost
Increase Productivity
Automation of various activities of system development and management
processes increases productivity
Reduce Maintenance cost

6. CATEGORIES OF CASE TOOLS
Supports the analysis and design phase
Includes tools for analysis model, reports and form
generation
Upper
CASE tools
Supports coding phase, configuration management
Lower
CASE tools
Also known as I-CASE
Supports analysis, design and coding phase
Integrated
CASE tools

7. CHARACTERISTICS OF CASE
TOOLS
Must support a standard software development methodology and standard
modelling techniques
A standard
methodology
Flexible in use of editors and other tools
Flexibility
Should be integrated to support all stages
Strong Integration
Must provide interface for automatic testing tools, to take care of regression
and other kind of testing software under dynamic requirement
Integration with
testing Software
Must be able to generate complex models from already generated code
Support for reverse
engineering
CASE tools must provide online tutorial
Online Help

8. APPLICATION OF CASE TOOLS
• To improve the software being produced
• To increase speed of development and design
• To improve the quality and completeness of
documentation
• Improve Software portability
• Ease and improve testing process through
automated checking
• Simplify program maintenance

9. ADVANTAGES AND
DISADVANTAGES
Advantages Disadvantages
Produce system with longer
effective operational life
Produce initial system that is
more expensive to build and
maintain
Produce system that more
closely meet user needs and
requirement
Require more extensive and
accurate definitions of user
needs and requirement
Produce system with excellent
documentation
May be difficult to customize
Produces system that needs
less systems support
Require training of maintenance
staff
Produce more flexible system May be difficult to use with
existing system
