JDBC - Data Dictionary

Jdbc Class Architecture


A Connection's database is able to provide information describing:

  • its tables,
  • its supported SQL grammar,
  • its stored procedures,
  • the capabilities of this connection, and so on.

This information is obtained with the getMetaData method of a connection. See DatabaseMetaData object.


If a DatabaseMetaData method indicates that a given feature is supported.

For example, if a JDBC API implementation supports the RowSet interface, it must also implement the RowSetMetaData interface.
