Model Driven Architecture (MDA®)
The Model Driven Architecture of the Object Management Group (OMG™) puts models into the center of application development. Implementation-independent models are expressed in UML® and are transformed into technology models as well as executable applications. MDA distinguishes between
- a Computation Independent Model (CIM), that represents a model of the business and that is completely independent of any IT systems.
- a Platform Independent Model (PIM), that is an implementation-independent model of the functionality of an IT system.
- and a Platform Specific Model (PSM), which is a technical model of an IT system that considers architectural constraints given by a chosen platform (e.g. J2EE, .NET or CORBA).
The Model Driven Architecture is supported by a number of tools in which focus on modeling in UML®. Primarily, the following different kinds of MDA tools may be distinguished:
- Modelling tools such as the classical UML CASE tools that offer convenient support to develop CIM, PIM or PSM models
- Transformation tools that perform at least partial model transformations (e.g. PIM -> PSM) in a flexible and configurable way
- Tools that support "Executable UML" (xUML) and thus provide a fully automatic path from implementation-independent specifications to executable applications.
KnowGravity and the Model Driven Architecture
KnowGravity Inc. offers since 1997 training in implementation-independent specification as well as in architecture modeling using UML. Based on KnowGravity's CASSANDRA platform, an xUML environment is available that is able to execute highly complex UML models immediately. This allows an early validation and correction of those models ("model-level Debugging"). As part of their coaching activities, KnowGravity's employees support the application of CASSANDRA/xUML in modeling safety-critical systems.

Unified Modeling Language (UML®)
The UML from Object Management Group (OMG™) is THE international acceppted modeling language.
KnowGravity put on the very first German UML Course in Switzerland
Since 1997, KnowGravity (then as part of Born Informatik) has put on UML Courses. Many improvements and updates to the actual version were supplied to the course material since then. KnowGravity holds not only public courses; we compose also very specialized courses for companies, typically whole teams. Every teacher is also user of the UML in its projects. Therefore, our course is based on experience of real world UML projects.
