Differentiate between a data and a form model:

• Different forms of the same data needed for different contexts, e.g.:

• Different devices

• Different access rights

• Form(s) may change without data model changes

• Data model may change without form changes

Evaluation


• Choose two DSLs and generate an editor for each one.

Part 1

• Conduct an usability test of the generated editors in cooperation with the industry partner.

Part 2

• Analyze and document the editor generation process including its advantages and disadvantages.

Part 3
