ODBMS

[Fici]

hi all,
I'm lucky because I'm starting a new java project (I don't have legacy
problems!).
I wound try a new repository solution so I'm finding information about
object DBMS (commercial or free products)!
can you help me? Have you tried some ODBMS?
tk.

In my personal opinion ODMBS is an attempt to bring back network-model data
base systems, which gave way to relational data base systems for good reason.

I prefer to use a good RDBMS like PostgreSQL and put my object model in my
Java code. There is a ton[ne] of power in the relational model, but of
course, it takes separate effort to develop skills in that arena on top of
one's object-oriented techniques. Lots of effort, maybe, but very well invested.

I suggest sticking with an RDBMS mediated by SQL in a DAO layer, but YMMV.

I have not tried it, but http://www.db4o.com/community/
seems as a possibility.

Hi Fici!
I would suggest you to read about db4o in comparison to RDBMS here
first:
http://developer.db4o.com/Resources/view.aspx/Reference/Basic_Concepts/Database_Models
And especially this article:
http://developer.db4o.com/Resources...Model_Comparison/RDBMS_And_OODBMS_Application
in order to understand if db4o is right for you

thanks all,
I know I can use a RDBMS with a persistent layer to map my object,
but I want to find out if somebody have used same ODBMS products.
