If you get yourself a book on databases, then databases are persistent
datastores that allow for certain things like concurrency, recovery, and
a few more
(sorry .. it's some time since I had this all in my brain without
consulting a book)
There are a few more properties - you could consult
http://www.amazon.com/exec/obidos/ASIN/020154329X
for it ..
There are e.g.
* hierarchical databases
* network databases and the like
and also relational database (RDBMS) which are databases in the above
sense based on the relational calculus by Chen.
For more .. really read a book
Cheers
