Hi, Mark!

I think in this way the search capabilities of my system will be very
reduced, I was thinking in something that allows me save, retrieve and
search objects, hiding the persistence mechanism, but I would like I was
capable to design several kinds of persistence implementations for flat file
systems, relational databases and so on.

Thanks,

Petterson F. de Paula
