Object Oriented Modelling and Design is a subject introduced in the 7th semester i.e (BE- sem 2) of Engineering for Computer and IT Engineering curriculum of Pune University. The subject is a compulsory subject for both (Computer and IT). This subject is really an important subject for a software engineer to model visual designs of a particular project.

Let us take an example: When you build any software using any particular software modelling techniques (say Waterfall Model) then you actually move or progress according to the protocol in a assigned way. The project starts with exploring the requirements of the project and then elaborating these requirements. After this step before the coding step starts , the team builds a visual model which helps the team to understand the different views of the system. It also helps to build a system in an easier and non haphazard manner. This is because the models once designed can be used as reference for the future during the development process. The team can then refer the different visual models for any information about the implementation of the project

To design these visual models we need to have a commonly agreed and accepted methodology or a simple protocol. Here comes UML into the picture. UML i.e. Unified Modelling Language is a Language which helps one to design visual models of a system in different views. UML is not a programming language and hence contains no coding stuff. It contains only diagrams which helps a designer develop a visual model of the system . There are many different types of diagrams available under the UML, which helps a user design different view models of a system. Some of them are : Class Diagrams , Activity Diagrams, Sequence Diagrams etc.

UML is a major part of OOMD according to the syllabus.

The syllabus for Computer and IT Engineering is almost the same.
