You can create and configure a JDBC resource to extract metadata from any relational database management system that is accessible through JDBC.
For relational databases that support JDBC, you can create and configure a JDBC resource instead of creating and configuring a custom resource. It is easier to manage linking between objects in connected resources using JDBC resources.
You can create a JDBC resource for any relational database that supports JDBC. You cannot connect to relational databases through ODBC. Where available, you should use the existing database resource types specific to that relational database instead of the JDBC resource. The database-specific resource types perform better and extract more metadata aspects. For example, to load metadata from an Oracle database, create an Oracle resource instead of creating a JDBC resource.
