They allow you to define a maximum amount of storage for a certain set
of data.
They help you to define the location of data.
They help you to define how much data can be used by which ressource.

You need to the command line in order to manage quotas - you might not
want that.
Quotas are handled differently on ever platform (if available).
With tablespaces you can assign 30mb to use a, 120mb to user b etc. ...
Table spaces are a nice abstraction layer to the file system.
