View is nothing but the logical representation of any sql query.

[emmily]

A view is a virtual table whose contents are defined by a query. Like a real table, a view consists of a set of named columns and rows of data. Unless indexed, a view does not exist as a stored set of data values in a database. The rows and columns of data come from tables referenced in the query defining the view and are produced dynamically when the view is referenced
