There's a simple, easy to use database included with OSX along with a similarly minimal spreadsheet. These will do fine for most home uses.
You can also get MySQL and/or PostgreSQL running under OSX with a level of effort that is comparable to getting them running under Linux or Windows.
OSX was, as of 10.3.9, supplied with a trial version of Microsoft Office for the Mac. That may, or may not, include Access -- I never started my Office trial, as I'd had enough of it on the PC. I also don't know if this is still true as of 10.4.x.
Aside from these well known DBs, there are quite a few other for-purchase products out there for the Mac. There is definitely no shortage of DB capability if you need it.
