- The middleware server (which can be a full-fledged J2EE Application server) can provide typical middleware services like caching (of connections, query results, etc.), load balancing, logging, and auditing.
- It depends on the number of databases the middleware has been configured to support.
- More exploration on the way the Java Driver interacts with the Middleware is required here.
