[MS-TDS-Diff]: Tabular Data Stream Protocol

Specifies the Tabular Data Stream (TDS) protocol versions 7 and 8, which is an application layer request/response protocol that facilitates interaction with a database server and provides for authentication and channel encryption; specification of requests in SQL (including Bulk Insert); invocation of a stored procedure, also known as a Remote Procedure Call (RPC); returning of data; and Transaction Manager Requests.

This document has been updated to define the difference between the TDS 7.x version family, in which encryption is optional and negotiated in the TDS layer, and the new TDS 8.0 version, in which encryption is mandatory and handled in the lower layer before TDS begins functioning.
