Thanks for the update. I guess my question is not presented in correct way. Here I am explaining it. I want to know which one is better from the following options. 1) Flex Data Services(FDS) directly communicating with DMS. (2-tier architecture) 2) FDS communicating with Hibernate using RemoteObject service. (server side model - three tier architecture).
The parameters we are looking in the above two options are performance & scalability. Thanks, --- In [email protected], "Seth Hodgson" <[EMAIL PROTECTED]> wrote: > > 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. > > Best, > Seth > > ________________________________________ > From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of pradhasan > Sent: Friday, January 18, 2008 2:29 PM > To: [email protected] > Subject: [flexcoders] Re: Hibernate.. > > In my Flex application with Weblogic appserver, which approach is > better for performance and transactions.
