Chapter 3. MDA Today

This chapter describes what has been achieved within the MDA at the time of writing. Hopefully, by the time you read this, the technology will have advanced somewhat further. This chapter gives an overview of the various OMG standards that can be used within the MDA, the tool support that you can expect, and development processes that you can use.

OMG Standards

The MDA is defined and trademarked by the OMG. We therefore first take a look at the OMG standards that play a role within the MDA framework.

OMG Languages

The OMG defines a number of modeling languages that are suitable to write either PIMs or PSMs. The most well-known language is UML. This is the most widely used modeling language.

The Object Constraint Language (OCL
