Before creating a platform metadata repository, set up DBMS back end. It is recommended to study server requirements before you start working. The preparation consists of creating a database and a user that will be administrator of this database.
The setup procedure differs for different DBMS:
Oracle is used by default.
Microsoft SQL Server is used by default.
Teradata is used by default.
PostgreSQL is used by default.
After executing all DBMS preparation operations, it is recommended to check user connection to created databse using DBMS means. If there will be any repository connection problems, it can be also needed to check user access permission and additional setup at DBMS level.
