JDBC provides four interfaces that deal with database metadata

  1. java.sql.DatabaseMetaData: about the database as a whole: table names, table indexes, database product name and version, and actions the database supports.
  2. java.sql.ResultSetMetaData: about the types and properties of the columns in a ResultSet object.
  3. java.sql.ParameterMetaData: about the types and properties of the parameters in a PreparedStatement object.
  4. javax.sql.RowSetMetaData: about the columns in a RowSet object.
