• Application Requester: Accepts SQL requests from applications and sends them to appropriate application servers for processing. Application programs can access remote data using this function.
• Application Server: Receives requests from application requesters and processes them. The application server acts on the portions of requests that can be processed, and forwards remainder to database servers for further processing.
• Database Server: Receives requests from the application server and other database servers. This server also supports distributed requests and forwards parts of the request to the database server to fulfill the request.
