I am reviewing a topic with the following scheme:

VFP Desktop Client <-> VFP Proxy Server (COM/DCOM) <-> Database (OLEDB Provider/SQL/DBC)

1) The VFP Client instances the VFP COM, sends requests [to] and receives responses (ADO/XML) [from] the VFP Proxy/COM.

2) The VFP Proxy processes requests from the VFP Client and forwards them to the OLEDB (as SELECT statements) and subsequently receives responses from OLEDB and then (after converting to ADO or XML) forwards [returns] them to the VFP Client.

3) The OLEDB Provider (SQL/DBC/database) recieves [SELECT] requests from the VFP Proxy and returns a [data] response [back] to the VFP Proxy.

Is there a name for this. I imagined it an n-Tear scheme, but the middle Tier does not apply businees rules other than [re]formating the data returned to the VFP Desktop Client (ADO/XML)? IS reformatting data a business operation?

Is it client server or is it n-Tier - or - is it something else?

Thanks
