OtfStructure

The following illustration shows the five major functional elements of the OTF are shown:

1. OTX-Desi­gner,
2. Screen-Desi­gner,
3. Database engine
4. Test environment and
5. Runtime environment

The Workflow Designer is the main input element. It gives the author an easy to understand, graphical view of the OTX-data in the form of a generic flow diagram. Objective: The author can simply understand the whole process from the graphical representation (eg for printing on A0 paper).

With the help of Screen-Desi­gners , surfaces (screens) are drawn for the input and output parameters and bound to the processes.

The Database Engine is mainly responsible for reading and writing OTX data validation, object search and reference management.

Main elements of the Open Diagnostic Framework

The test environment is used to run and test the processes in the development environment (eg for debugging or unit testing framework).

The OTX-runtime executes the sequences both within the development environment, and within a runtime environment (eg in the garage or in the EOL programming).
