Delphi and Oracle

I have Personal Oracle 7 on my pc.  I've installed Delphi 2 client/server
edition (I'm running Windows 3.1).  I've never used Delphi and I can't
figure out how to access the tables in Oracle thru Delphi.  I'm sure the
answer's right in front of me, but if anyone is using a similar setup
could you please let me know how to connect Delphi to Oracle running
locally.  Thanks a lot.
