What is a view? What is it used for? Give examples when a view can be used for your project.
Solution
View is way of portraying information in a database by arranging data items in certain order by
highlighting certain items. Often thought of as Virtual table, doesn't store data itself but pulls out
from one or more tables.
Views are used according to purpose so that we query on selective data not whole of it. Using
views saves us lot of querying resources.
For example, people query telephone directory to search for Street Address associated with
Phone Number. We can create View which stores 2 columns namely Phone number and Street
Address ignoring all other fields.
