Replicating Data

One approach that may support efficient access to dissimilar applications as above may be to give access to every of the applications from dissimilar replicated files of the data. Each of the file may be prepared in a dissimilar way to serve the requirements of a dissimilar application. For instance, for the problem over, we may give an indexed sequential account file having accounted number as the key to account holders and the bank teller. A sequential file in the order of permissible loan limit to the Loan officers and a sorted sequential file in the order of balance to branch manager.

All of these files therefore differ in the organisation and would need different replica for dissimilar applications. Though, the Data replication brings in the problems of inconsistency under updating environments. Therefore, a better approach for data access for multiple keys has been proposed.
