Is it possible to implement a lightweight database using Blackberry Persistance options?

First I would like to explain why I want to use Blackberry Persistance alternate parameters and not a Blackberry database, say SQLite. The reason is that the application I'm developing wants to be used on all previous versions of Blackberry, not just those with OS 5.0 or higher.

Now, getting back to the actual question, I have a database that I want to replicate for use in the Blackberry app. The database has 8 tables, and each table has approximately 12 different columns. One of the tables has 1000 rows. Now, if I had to implement this DB for a Blackberry application, with the understanding that it would work on all Blackberry versions, what would be the best way to implement it?
