hipergate Data Model Manager

This class is used for programatically creating the full underlying data model for hipergate Java packages.

It may be used as an alternative method to database dumps for initial data loading, or, also, as a tool for porting the data model to a new DBMS in a structured way.

de.hpi.eworld.core.ModelManager
The ModelManager is the central data management class in eWorld. It manages all ModelElements. If any of the plugins wants to add or remove a ModelElement, it has to do so by calling this ModelManager. Singleton class: There is only one ModelManager
