Unified Modeling Language

UML stands for Unified Modeling Language. This is a standardized way of writing diagrams, because a sentence may often lead to a lot of interpretations. The current standard is UML 2.5.1 and OCL 2.4.

OCL = Object Constraint Language. This is introduced in database diagrams, and this is used to add constraints (ex: age > 0) to something. You can use it in class diagrams too.


You got a lot of diagrams listed on Wikipedia, but we will cover these


I will be using these to create diagrams.
