This document discusses an assignment submitted by five students on the topic of automated tools for system analysis and design. It provides an introduction to computer-aided software engineering (CASE) tools, which are automated software tools used by systems analysts to develop systems. It discusses the objectives, categories, components and general types of CASE tools, including diagramming tools, report generators, analysis tools, repositories, documentation generators and code generators. It provides examples of specific CASE tools.

3. Introduction to CASE
•Computer Aided Software Engineering(CASE)
Automated software Tools used by System Analyst to develop
system.
Used to support activities throughout the system development life
cycle(SDLC)
Increase productivity
Improve overall quality of a system.

4. The use of CASE
•Purpose of case is to facilitate a single design
philosophy within an Organization.

5. Objectives of CASE
Improve quality of System Development;
Increase speed of development and design;
Ease and improve testing process;
Improve project management;
Improve Project maintenance;
Improve software portability ;
And so on.

7. Categories of CASE Products
Reverse Engineering
Reengineering

8. Components of CASE
Upper Case -- CASE tools designed to support the information
planning and the project identification and selection, project initiation
and planning, analysis and design phases of the SLDC.
Lower Case -- CASE tools designed to support the implementation and
maintenance phases of the SLDC.
Cross-Life cycle Case – CASE tools designed to support activities that
occur across multiple phases of the SLDC.

9. General types of CASE Tools
 Diagramming Tools;
 Computer Display and Report Generators;
 Analysis Tools;
 Repository;
 Documentation Generators;
 Code Generators;

10. Upper and lower CASE tools are named as such because of where
the phases they support are in the Waterfall Model (see below)

13. CASE Diagramming Tools
 Enable representation of a system and components visually.
 Effective for representing process flows, data structures, program
structures.
 Several types of diagrams.
Data Flow Diagrams (DFD);
Functional Hierarchy Diagrams;
Entity-relationship Diagrams;

17. CASE Form and Report Generator Tools
Case tools that support the creation of system forms and reports in order
to prototype how system will look and feel to users.
Two Purpose
•Create, modify and test prototypes of computer display forms and reports.
•Identify which data items to display or collect for each form or report.

18. Case Analysis Tools
Enable automatic checking for incomplete, inconsistent or
incorrect data on diagrams.
Types of analysis vary depending on the organization’s
development methodology and features of CASE
environment.

19. Case Repository
•Holds complete information needed to create, modify and
evolve a software system from project initiation and
planning to code
•Two primary segments---
Information Repository ;
Data dictionary;

21. Case Documentation Generator Tools
Enables the easy production of both technical and User
documentation.
Allow creation of Master templates used to verify that
documentation confirms to all stages of SDLC .

22. Case Code Generation Tools
Enable the automatic generation of program and database
definition code directly from the design documents,
diagrams, forms and reports stored in the repository.
Example

23. Visual and Emerging Development Tools
Object Oriented Development Tools –
 Object
 A group of program and data that is built to perform common functions
within a system.
Easily Reused.
Encapsulation.
 Development Environment includes pre defined Objects reuse of code.

24. Some Popular Tools –
Microsoft Visual Studio.
Delphi
PowerBuilder
ColdFusion
