The database user gets all the results. Retrieves data based on the keywords in the query entered by the user. It usually involves giving a piece of information called the key, and ask to find a record that contains other associated information. In the information retrieval system, there is a set of words that convey the semantics of the information that is required whereas, in a data retrieval system, a query expression is used to convey the constraints which are satisfied by the objects. This book also supplies developers of social-semantic applications with an understanding of the key concepts and methods of both fields and describes real-world applications incorporating social and semantic metadata. Without a file system, information placed in a storage medium would be one large body of data with no way to tell where one piece of information stops and the next begins.
