I am looking for some guidance when replacing custom SOAP Web Services with SF SOAP Web Services.

Background

We are looking to consider moving one of our database applications from in-house Oracle Database to SalesForce for various reasons. I would not go in those reasons here.

We have created custom objects in SF that maps to Oracle Database and are considering SF partner solution for moving/syncing SF database with Oracle.

There are already a bunch of Java applications that are integrating with the Oracle database using Web Services (Just 5). We are looking to replicate these Web Services in Salesforce with the identical signature so that these applications can run with minimal impact due to this change.

Guidance

SF has limit of 10 queries that a user can execute concurrently. Moreover, if multiple users are signing in they share the same session. Therefore, looks like we will need to write a Web Services connection wrapper - so that Client Apps connects to Salesforce - they arre connecting using different user-ids that is tied to client app sessions. Is this the right approach?



Is there anything else that would help so that there is minimal impact to Client applications? Any alternatives?

Thanks,
