Introduction

Computer-aided systems engineering (CASE),

also called computer-aided software

engineering, is a technique that uses powerful

software, called CASE tools

In addition, you will learn about integrated

software development environments

CASE Terms and Concepts

A typical CASE tool is actually a set of

individual tools that share a repository of

information

Repository

When you define a data element in the repository,

you can assign a data type and format, a range of

acceptable values, and one or more aliases

Integrated Development Environments

Pros and Cons of Integrated Development

Tools

Is highly effective because it is an integral part of

the vendors software package

The only possible disadvantage is that each IDE is

different and requires a learning curve and skills

that might or might not be readily transferable CASE tools can be used in any development

environment

CASE Tool Examples

You can choose from dozens of vendors and

CASE tools that offer a wide range of functions

Three leading CASE tool suppliers: Visible

Systems Corporation, Telelogic Software, and

Rational Software

CASE Tool Examples

Visible Analyst

Visible Systems Corporation is an important player

in the software development market

Also provides a full range of Help features,

including the error message analysis screen

CASE Tool Examples

Rational Software

IBM offers many systems development and

modeling products, including a powerful tool

called Rational System Architect

Stresses modeling and collaboration, and is a suite

of tools that can align processes, information, and

technologies

CASE Tool Trends

New Products and Features

Another trend is the increasing use of integrated

development environments

An IDE typically includes built-in tools such as real-

time error detection, syntax hints, highlighted

code, class browsers, and version control

CASE Tool Trends

Method-Specific CASE

Tools

Structured analysis

Object-oriented analysisand design (OOAD)

The most recent trend is

the popularity of agile

methods

Toolkit Summary

CASE tools are software programs that systemdevelopers use to help them design andconstruct information systems

A repository is a database that serves as acentral storage location for all informationabout the system being developed

An integrated set of CASE tools can be used tomodel, document, engineer, and construct theinformation system

Toolkit Summary

Forward engineering means translatingbusiness processes and functions intoapplications

A CASE tool can handle many programdevelopment tasks

Two trends seem clear: CASE tool vendors will

continue to include powerful new features,and the popularity of object-oriented toolswill continue to grow
