The driver provides a standard set of catalog tables that maintain the information returned by the methods of the JDBC DatabaseMetaData, ParameterMetaData, and ResultSetMetaData interfaces. If possible, use JDBC metadata methods to obtain this information instead of querying the catalog tables directly.

The driver also provides additional catalog tables that maintain metadata specific to the driver. This section defines the catalog tables that provide driver-specific information. The catalog tables are defined in the INFORMATION_SCHEMA schema.
