CASE Tools: In information technology (IT), a computer-aided system engineering (abbreviated as CASE) tool is software which assists with software development. The major purpose of employing a CASE tool is to generate error-free, easy to sustain program code. It too permits users to develop software systems more rapidly than would be possible devoid of the utilization of such a tool.
The CASE tool frequently permits developers to program visually and also uses Object Oriented Programming (OOP) methods. The Unified Markup Language (UML) design tool is an illustration of a CASE tool. The System design documents and program code might be produced by the tool as part of the visual design, therefore reducing development time and rising accuracy of the code and documents.
