Why do you create a View in a database?

Question

When and Why does some one decide that they need to create a View in their database? Why not just run a normal stored procedure or select?

Answer 1

I like to use views over stored procedures when I am only running a query. Views can also simplify security, can be used to ease inserts/updates to multiple tables, and can be used to snapshot/materialize data (run a long-running query, and keep the results cached).

I've used materialized views for run longing queries that are not required to be kept accurate in real time.
