Extension: It is the number of tuples present in a table at any instance. This is time dependent.
Intension: It is a constant value that gives the name, structure of table and the constraints laid on it.

The description of data base is called in tension or database schema,which is specified during database design and is not expected to change frequently.
The actual data in a database may change quite frequently.The data in a database at a particular moment in time is called a extension or database state or snapshot.
