Session 7 - In this session we take a deeper look at OCL expressions and what you can do with them. OCL is a complete language that can act on everything that you have in your model, it has operators on objects and on collections. The ocl language is a functional language –different in approach compared to imperative languages like javascript and c#. The ocl language is optimized for querying your model. It uses a bit of set theory from your math classes. It is compact in the sense that it does a lot with short snippets. OCL is defined by ObjectManagementGroup OMG.
