The role of views in SQL server is kind of virtual tables. The view also has rows and columns as they are in a real table in the database. You can create a view by selecting fields from one or more tables present in the database. The view can either have all the rows of a table or specific rows based on certain condition. The VIEW in SQL is a logical subset of data from one or more tables. The view is used to restrict data access.
A Views can represent a subset of the data contained in a table; with the result that a view can limit the degree of exposure of the underlying tables to the outer world:
The given user may have permission to query the view, while denied access to the rest of the base table.
The views can join and simplify multiple tables into a single virtual table. The views can act as aggregated tables, where the database engine aggregates data (sum, average, etc.) and presents the calculated results as part of the data
The views can hide the complexity of data; for example, the view could appear as Sales1001 or Sales2001, transparently partitioning the actual underlying table
The views take very little space to store; the database contains only the definition of a view, not a copy of all the data which it presents.
Views may provide additional security, depending on the SQL engine used. 
The syntax for creating a View
CREATE or REPLACE VIEW view_name 
and  and  AS
and  and  SELECT column_name(s)
and  and  FROM table_name
and  and  WHERE condition
