Start model
A start model is a model that serves as an entry point into a database. It is useful to use the model to represent the structure of a database.
You can assign models to the objects of the start model. By clicking the 
assignment icon, users can jump to different models stored in the database structure, for example, to models in the groups for the organizational models or groups for process models.
For each database, a model can be set as the start model, which is displayed in Home.
