This mass of data is stored in the larger repositories and these repositories are also growing day by day and it will continue like that, it is never ending process till the scope of systems exist. Retrieving data from the large data tombs or data buckets or large repositories is also a challenge. Improved Information Retrieval (IIR) should fast and accurate. Data will spread in distributed databases for any organizations around the globe. End user will interact with the web server and web server stores the user details in an index that is available in database relation, that process is said to be WUM. Challenge is chased by maintaining index with a format and storing information in sequential manner.
