In order the DBMS (Database Management System) to function consistently, it must have available information about the whole structure of the database. The most important information certainly refers to the database objects (tables, views, columns), how they are connected, primary and external keys, indexes, constraints, furthermore, which users can access the objects and with which authorities, etc. All of the above represents knowledge about the database and must be represented in its data model, i.e. in the meta model.
This paper provides an overview of meta model architecture, its objects (tables and views), i.e. It shows meta model segments that maintain their internal integrity as well as the integrity of the business data model through their connections.
The upper case tool used in this work is MySQL Workbench. Reverse engineering functionality was used to obtain model segments.
