1.      Database Management

One of the basic principles of good data base management is that data redundancy should be minimized. Such situation can occur when different files are created and a particular data repeats in more than one files. In such case, any data change would have to be corrected in each file in which it appears. in good data base management technique, data accuracy improves, because a change, once made would immediately be available to every program.

Using the data base approach, data is treated as an important organisation resource and not as the property of an individual programmer or department. Often, to improve accessibility, logically related elements of data are linked together. All the information is collected into a single integrated base instead of a series of independent files. Building well-planned integrated data base is a tough job. Data base design starts with the definition of organisation�s data resource, identifying key inter-relationships between individual elements of data, putting the pieces together as an integrated whole.
