[Objectbridge-jdo-dev] Non-JDBC data sources

[David Z. <dv...@at...>]

I know, that OJB's focus sharpness (faq: It's concerned with O/R mapping and
nothing else.) is design/manage advantage, but I work on project, where it's
crucial to integrate disparate data sources (RDBMS, ODBMS, XML based DBMS,
flat-files, vendor specific formats..). I decided not to use closed,
non-free solutions at all, so OJB (open-source, clearly designed,
scalable...), seems to be suitable as a persistency-heart.
Could you advise how to get on with OJB?
1) use OJB as a single persistency adaptor, manage several ODMG
implementations, make some fascade to hide it, e.g. solve distributed
transactions...?
2) extent OJB (add persistency adpators to OJB) - if publically useful,
release them under LGPL as modular OJB's parts/add-ons?
2.1) is this posible without (negative) impact on OJB's actual design
3) something else?

In the roadmap there is (4me) a bit mysterious  sentence "provide
distributed Meta-Object Protocol access through PersistenceBroker API"
Somewhere in OJB doc I read about possibility to build my own
PersistenceManager. Does it relate to mentioned problem?

Thanks for reply

PS: I know, I can suck all wanted info from API, but I thing, you (OJB
experts) can answer quickly and painlessly.

BTW thanks for OJB, well done!
