We have a financial trade calculation engine requirement which needs to cache a variety of different price curves inside the "server"  as it is not practically to move and keep 100+M data in each client machine. The client  need to do a remote call to access the "server" and the server will based on the passing parameters to do the option module calculation. The server will cache the result in the server so that if another client ask for the evaluation with same parameters, the server just simply returns the result instead of recalculate it again as it is very expensive procedure.
 
As I know, there is no data stored in the BOS, what is your recommended approach? Do we need to create our own server applicaiton to handle the client side call and inside our server to use your data acccess layer to access DB?

Use a Remote Service Method.  See the advanced tutorial :

390. Remote Service Methods

A Remote Service Method (RSM) is a method that resides in a server-side assembly and is marked so that it can be called from a client-side DevForce application. Remote Service Method calls are supported in DevForce via PersistenceManager methods named InvokeServerMethod() and InvokeServerMethodAsync(). Remote method calls are particularly useful for (a) operations that must touch a great deal of data that is not otherwise needed client-side after the operation completes; or conversely, for (b) retrieving to the client large quantities of possibly unrelated data in a single trip between client and server. When invoked asynchronously for the latter purpose, such remote method calls can deliver great client-side performance.
