Define view? how it is related to data independence, Database Management System

Assignment Help:

 

A View may be defined of as a virtual table, that is, a table that does not really exist in its own right but is instead inferred from one or more underlying base data table. There is no stored file that direct shows the view instead a definition of view is loaded in data dictionary. Restructuring and growth of base tables is not shown in views. Thus the view may insulate end users from the effects of developing and growth in the database.
