The entities that must be managed in the application can be derived from the user stories described.

The entities with their properties are described in the data model of the application:

• Management of products and product versions
  • Product with name and quantity of assigned product versions, as well as assignment of persons in different functions (manager, tester, developer)
  • Product version with name
• Ticket management
  • Ticket with name, description, assignment of one product version each as source and target version

With the Model Editor in the Administration => Development => Model Editor tab, TopLogic provides a tool for graphically describing such data models in language space for Unified Modeling Language (UML) class diagrams.
