Hi,
Advantages of views:
1. View the data without storing the data into the object.
2. Restict the view of a table i.e. can hide some of columns in the tables.
3. Join two or more tables and show it as one object to user.
4. Restict the access of a table so that nobody can insert the rows into the table.
Disadvatages:
1. Can not use DML operations on this.
2. When table is dropped view becomes inactive.. it depends on the table objects.
3. It is an object, so it occupies space.
