Model Mapping
In many modeling projects the problem arises of communication between teams of analysts and architects and the database development teams.
HOPEX Data Architecture offers two modeling levels:
The logical level which describes data modeling in terms of entities and relationships and is intended for analysts and developers.The physical (or relational) level, which describes the database in terms of tables and interfaces with the DBMS. This level is intended for the designer and the database administrator.By enabling change from one data model to another, the database editor favors consistency between the architecture of data and its support systems.
