Connecting to a database

Before proceeding to analyze data in a specific database, set up the connection to this database. You can create a connection on the DataBase Management System (DBMS) and show database content.

For more information about the supported databases for profiling data, see .

Connections to different databases are reflected by different tree levels and different icons in the DQ Repository tree view because the logical and physical structure of data differs from one relational database to another. The highest level structure "Catalog" followed by "Schema" and finally by "Table" is not applicable to all database types.

For further information, see Catalogs and schemas in database systems.
