HI I learned about teneo and cdo only the last couple of days. I like
soemthink about cdo, but I wonder if its hwat I actually want. I have a
typical three tiered architecture. currently i have JPA entities
persited with hibernate in my domain model. what I like is that CDO
promises to handle the lazy loading of the model to the client (which I
currently cant with hibernate) for a single business object i always
have to load the whole object graph and transfer it to the client. But I
come from relational database background. so I wonder if i have an emf
model for everything, how can i query it (for e.g. give me all persons
with name like '%Thomas%' ? how is the cdo persistence layer ? I want to
be db independant (at least postgres, sql server, oracle). I have tons
of data, what about performance issues ? with hibernate i can tune many
things on the db. would be glad if you can teach me something about cdo :)

Regards Thomas
