Just need more insights between these two database since they are my only options for now.

So my question is which one is better...

Scenario: The system that i'm planning to develop is only for a small type business. Around 4 users / 4 pc / 1 pc would be where the database is installed. The other pc/ clients will just connect to the server pc.

ORACLE
PROs
I went to the oracle site and found out that Oracle Database 10g XE is a free database and can be used for small type business with no extra charge. Although it has limitations as expected from a free product.
CONs
Seems more difficult to use.

MS ACCESS
PROs
Seems easier to use.
CONs
Not sure if it has a free database download.

Please help.. THanks!
