and store it on to the search engine’s indexed database.

Motivation: Why Deep Web

• Then why Google fails?

• Most of the Web's information is buried far down on dynamically generated sites.

• Traditional web crawler cannot reach there.

• Large portion of data are literally ‘un-explored’

• Need for more specific information stored in databases

• Can only be obtained if we have access to the database containing the information.
