| Request processing flow |
Request processing follows these steps:
The client application issues a request (for example, a select statement).
The client API (for example, CT-Library, DB-Library, or ODBC) receives the request and sends it to the access service.
The access service receives the request, transforms it (if needed), and executes the request.
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.
The following figure shows the processing flow of the APIs through DirectConnect to AS/400.
