Hi Koeytuhay,

Thanks for your post. First of all, since UML is a complex language, please do not aim to understand everything in UML. Actually it is normal for a company to apply only about 20% of UML knowledge on their development, and it is fairly enough to complete the development (just like you apply only about 20% of all the English words in you life but still can survive).

In order to know how many models are in UML and which diagrams are associated with which model, you can refer to the OMG UML Superstructure at the following links:
Version 2.0
http://www.omg.org/spec/UML/2.0/Superstructure/PDF/

Version 2.1.2 (current version)
http://www.omg.org/spec/UML/2.1.2/Superstructure/PDF/

I suggest you can read some books for UML beginners such as “UML Distilled (Second Edition)” written by Grady Booch, Ivar Jacobson and James Rumbaugh. If there is any further inquiry, please do not hesitate to contact me.

Best regards,
Lilian Wong

Thanks for the reply. I gone through this document sometimes back, but I could not find exact what actually I want. I dont want so much details, I want just the list of UML models and their concerned diagrams.

Hi Koeytuhay,

Thanks for replying. UML model is a graphical notation of Unified Modeling Language (UML).
In the field of software engineering, UML is a standardized visual specification language for object modeling. It is a general-purpose modeling language which includes a graphical notation (UML model) for creating an abstract model of a system.

You can reading some UML books which is suitable to beginners, so that you can get more fundamental knowledge that facilitate your UML modeling work.
For instance: UML Distilled (Second Edition), written by Grady Booch, Ivar Jacobson and James Rumbaugh.
