I'm not sure what you're asking. The Data Management Service in LCDS relies on an adapter layer to integrate into your backend. If your backend is a raw database, you may want to use the SQLAssembler for a quick prototype. If you have a Java domain model that uses Hibernate for persistence, use the HibernateAssembler. If you have some other backend (say an XML database or an in-memory data model accessed via a data grid API) you can write a custom assembler that would expose it to the Data Management Service so that Flex clients can interact with it simply and consistently using the client-side DataService component.
It's not a matter of "Data Management Services Vs Hibernate". The Data Management Service is just providing a nice client-server API for plugging clients in to your backend data, which may or may not involve Hibernate. I'd recommend focusing on the server-side programming model you want to use for managing your data, and go from there. You'd have more opportunities for tuning (caching, write policies, etc.) using the HiberanteAssembler or a custom assembler than you have with the SQLAssembler which executes raw, parameterized queries against your database.
