Specifies the Tabular Data Stream Protocol, which is an application layer request/response protocol that facilitates interaction with a database server and provides for authentication and channel encryption negotiation; 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 for SQL Server 2019 Community Technology Previews (CTPs) as follows:

●  Included support for enhanced confidentiality and security through enclave technologies that enable cryptographic operations and other operations in Transact-SQL queries on encrypted columns inside the local database system.

●  Added information about the new data classification feature, which supports information protection by providing a framework in which data classification metadata are used to help secure sensitive data as it propagates outside database boundaries to applications, services, reports, and so forth.

●  Defined support for the client and server to be able to send and receive UTF-8 encoded data.
