This discussion seems to be quite focused on RDBMS (the title is 'JDBC', the description mentions 'ODBC' and 'SQL' ...), however I'm not sure I like pigeon-holing my data into a relational model when the data is not tabular but composed of individual objects. Thus: does anybody have any suggestions for a really simple OODBMS that I could check out to get started? Or any tips on implementing one? Thanks.

Dan, If you just want to experiment, there are a whole bunch of free databases out there. This database list has quite a few OODBs on it. You may also want to consider using an object-relational mapping tool, such as Hibernate or Castor.
For some reason, Ozone was not included in that list, which is strange because AFAIK it's the most mature open source OODBMS out there. Disclaimer: I haven't used Ozone myself, except for installing it once back in the day and running a "hello world".
