Load - unload utilities, Database Management System

Assignment Help:

These permit the user to unload a database or parts of a database and reload the data on the similar machine, or on another machine in a dissimilar location. This can be useful in many situations, such as for creating backup copies of a database at a definite point in time, or for loading data into a latest version of the database or into an entirely dissimilar database. These load/unload utilities may also be used for reorganizing the data in the database to improve performance, such as clustering data together in a exacting way or reclaiming space occupied by data that has become obsolete.

Reporting/Analysis Utilities:

These are used to report and analyse on the data contained in the database. This may have computing values from data, analysing trends in data or displaying data that meets some particular criteria, and then printing or displaying a report having this information.
