A database containing surface water; ground water; crop area and crop production; meteorological information containing rainfall, temperature, humidity, sunshine, wind speed; soil information containing soil type, texture, chemical and physical properties; social information containing population, literacy rate, land holdings etc, was created using MS-Access. The database tables are created to store different data basin-wise, district-wise and block- wise.

Under Integrated National Agricultural Research Information System (INARIS), E-R diagrams for six databases namely ground water database, surface water database, water pricing database, water quality database, project database and technology database are prepared.
