This is a good start to see how they are used in PostgreSQL.
Briefly, a view is a 'virtual' table -- you create a view with a select
statement that can relate data between different tables or use a subset of
data from a specific table. You can think of them as a 'saved query'.
Once you create a view, you can then query them just like a normal table.
You cannot, as of yet, update views in PostgreSQL, they are read only.
