The objectives of DBMS can be narrated as follows: 1. The documents and the queries are represented in a similar manner, so that document selection and ranking can be formalized by a matching function that returns a retrieval status value (RSV) for each document in the collection. The main objectives of Information retrieval is to supply right information, to the hand of right user at a right time. Audio, vedio, text flows are introduced as a representation of tree. The IR system contains a certain set of words that defines the logic to deal with the information.Earlier, the documents were represented through some keywords or a set of indexes. Cost include factor such as response time, time taken by the system to provide an answer. Small errors are neglected. The existing of the information retrieval tools cannot solve the end of user information needs. Early Developments: As there was an increase in the need for a lot of information, it became necessary to build data structures to get faster access. Information is a vital resource for corporate operations, and it has to be managed effectively, just like any other vital resource.
