The main objectives of Information retrieval is to supply right information, to the hand of right user at a right time. This is one of the information retrieval models that is widely used. DBMS is a software system for creating, organizing and managing the database. The probabilistic model is rather simple and takes the probability ranking to display results. Systems analysis is an iterative process that continues until a preferred and acceptable solution emerges. Feature selection can be defined as the process of reducing the input of processing or finding the essential information sources. usually text which satisfies an information need from within large collections which is stored on computers. Digital libraries use this system to sort and find the books according to the requested name, genre, or author name. In the process, first, the document surrogates are created to represent each document. 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.
