What is CASE?
⚫ Computer Aided Software Engineering (CASE) is the use of software tools
to assist in the development and maintenance of software.
⚫ Computer-Aided Software Engineering (CASE) is the domain where
software tools used to design and implement applications
⚫ Software systems that are intended to provide automated support for
software process activities
❑ Automated support definition: Automated support is that we use some software to develop
another software. For example if we need diagram representation of data in the form of
flow chart and we develop it by the help of a flow chart maker (software tool used to
develop flow charts) rather than developing manually(by hand). This is called automation
support.

Importance of CASE
⚫ CASE allows for rapid development of software.
⚫ Produce system with a longer effective operational life
⚫ Produce systems that most closely meet user needs and requirements.
⚫ Produce system with excellent documentation
⚫ Produce systems that needs less systems support
⚫ Produce more flexible systems

Scope of CASE
⚫CASE tools can be grouped together if they have similar
functionality, process activities and capability of getting
integrated with other tools.
⚫The scope of CASE tools goes throughout the
SDLC(System Development life Cycle).

CASE Support to SDLC

CASE Tools
❑ CASE tools can be broadly divided into the following parts based on their use
at a particular SDLC stage (Detail of tools is at slide 10 onward) :
1) Upper Case Tools - Upper CASE tools are used in planning, analysis and design
stages of SDLC.
2) Lower Case Tools - Lower CASE tools are used in implementation, testing and
maintenance.
3) Integrated Case Tools - Integrated CASE tools are helpful in all the stages of
SDLC, from Requirement gathering to Testing and documentation

CASE Tools
⚫CASE Tools Categories
⚫Major categories of CASE tools are:
o Diagram Tools
o Processing Model Tools
o Project Management Tools
o Documentation Tools
o Analysis Tools
o Design Tools
o Configuration Management Tools
o Change Control Tools
o Programming Tools
o Prototyping Tools
o Web Development Tools
o Quality Assurance Tools
o Maintenance Tools

CASE Tools
Computer Aided Software Engineering (CASE) 12/1/2022 10
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.
• Diagrammatic Representation of system.
• Help to supervise a process across many different
• fields.
• Examples
• Flow Chart Maker tool for creating state-of-the-art
flowcharts.
• Rational Rose used for creating
• SmartDraw, Gliffy, Visio and many others

CASE Tools
Processing Model 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.
• Examples
• EPF(Eclipse Process Framework)
Composer

CASE Tools
Project Management Tools
• These tools are used for project planning, cost
and effort estimation, project scheduling and resource
planning.
• These tools help Managers to comply project execution
with every mentioned step in software project
management.
⚫ Project management tools help in storing and sharing
project information like time tracking etc. in real-time
throughout the organization.
• Examples
• Creative Pro Office,
• Trac Project,

CASE Tools
Documentation Tools
• Documentation in a software project starts prior to the software process,
goes throughout all phases of SDLC.
• Documentation tools generate documents for technical users and end
users.
⚫ Technical users are mostly in-house professionals of the development team
who refer to system manual, reference manual, training manual, installation
manuals etc.
⚫ The end user documents describe the functioning and how-to of the system
such as user manual.
⚫ Training Manuals, Installation Manual, User Manuals can be generated by
documentation tools.
⚫ Examples
⚫ Doxygen,
⚫ DrExplain,

CASE Tools
Analysis Tools
• These tools help to gather requirements,
automatically check for any inconsistency, inaccuracy
in the diagrams, data redundancies or erroneous
omissions.
⚫ Examples
⚫ Accept 360,
⚫ Case Complete for requirement analysis,

CASE Tools
Design Tools
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.
These tools provides
detailing of each
module and
interconnections among
modules.
Animation, Modeling
and Rendering of
projects can be
generated by design
tools
Examples
Maya
KeyShot

CASE Tools
Configuration Management (CM)
Tools
⚫ Configuration Management (CM) Tools
• An instance of software is released under
one version.
• Configuration Management tools deal with
• Version ,Baseline configuration and
Change Control Management
• Bug tracking and Blogging can be done
by CM tools
• Examples
• Git, (version control software)
• Accu REV.

CASE Tools
Change Control Tools
⚫These tools are considered as a part
of configuration management tools.
⚫They deal with changes made to the
software after its baseline is fixed or
when the software is first released.
⚫CASEtools automate change
tracking, management, code
management and more.
⚫Examples
⚫iTop

CASE Tools
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.
⚫Examples
⚫Cscope to search code in C,
⚫Eclipse.

CASE Tools
Prototyping Tools
⚫Software prototype is simulated version of
the intended software product. Prototype
provides initial look and feel of the product
and simulates few aspect of actual product.
⚫Prototyping CASE tools essentially come
with graphical libraries. They can create
hardware independent user interfaces and
design.
⚫These tools help us to build rapid prototypes
based on existing information.
⚫Examples
⚫Serena prototype composer,
⚫Mockup Builder.

CASE Tools
Web Development Tools
⚫ These tools assist in designing
web pages with all allied elements
like forms, text, script, graphic
and so on.
⚫ Web tools also provide live preview
of what is being developed and
how will it look after completion.
⚫ Examples
⚫ Adobe Edge Inspect
⚫ Foundation 3

CASE Tools
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.
⚫Examples
⚫JMeter.
⚫AppsWatch,

CASE Tools

Maintenance Tools
⚫Software maintenance includes
modifications in the
⚫software product after it is delivered.
⚫Automatic logging and error reporting
techniques, automatic error ticket
generation and root cause Analysis are
few CASE tools, which help software
organization in maintenance phase of
SDLC.
⚫Examples
⚫Bugzilla for defect tracking,
⚫HP Quality Center

Summary
⚫ From above material it is concluded that CASE have significant
impact on
⚫ Software Quality
⚫Simply stated, CASE can signification contribute to a reduction of errors
in each development phase.
⚫ Software Maintenance
⚫Full and updated documentation by CASE tools enables thorough
examination of possible software adaptations(versions) for new
applications.
⚫ Project Management
⚫CASE tools can significantly contribute from deviation(going away) of
budget and schedule from a plan and the reduction of high error rates
and shorter correction cycles when needed.
