Metadata is the information about data such as properties and structures of a table. For example a data base contains the employee table that has the name, address, salary and department columns. The Meta data of the employee table includes information, such as name of the columns, data type of each column, and constraints to enter data value in the table columns. JDBC API provides two metadata interfaces to retrieve the information about the database and result set, Database Metadata interface and Result Set Metadata interface.
