Advantages:
•Data isn't dependent on structure of the database.
•Restrict access to a database.
•Subset of data contained in a table.
•Join and simplify multiple tables into a single virtual table.
•Acts as aggregated tables, where aggregated data (sum, average etc.) are calculated and presented as part of the data.
•Gives real time data.
Disadvantages:
•Rows available through a view are not sorted and are not ordered either.
•Cannot use DML operations on a View.
•When table is dropped view becomes inactive, it depends on the table objects.
•It affects performance, querying from view takes more time than directly querying from the table
