Figure 6-1 shows the processing flow from the client application through the access service to the database.
Figure 6-1: Request processing flow
As shown, request processing consists of these steps:
When the client application issues a request (for example, a select statement), the client Application Program Interface (API) receives the request and sends it to the access service.
The access service receives the request, transforms it as specified in its configuration, and executes it.
After the request processes, the access service converts target datatypes to Open Server datatypes and returns the results to the client application.
The client application disconnects from the access service.
