How can I access the database?

Application programs can access the models and the instance data within the repository.

erSQL-Query-Language:

The erSQL-Query language provides a direct data access for power users and a programming interface to retrieve data objects from the database. The retrieved objects can be processed by an application program, can be handed over to a service-consumer, can be used as interface to a reporting system (BIRT) or displayed directly on a screen.

Power users and programs use the erSQL-query language to navigate through the database and retrieve data (objects). The query language uses the relationships of the conceptual model for navigation instead of "joining data from tables". The query language is also the ideal interface for the BIRT reporting system.

API - Application Programming Interface

The Metasafe API provides a rich functionality to read, analyze, update, query the data models and the instance data in the the database.
