1.4 Relationship to Other Protocols
Microsoft SQL Server Analysis Services uses the SOAP messaging protocol for formatting requests and responses as specified either in [SOAP1.1] or in [SOAP1.2-1/2007] and [SOAP1.2-2/2007]. It transmits these messages by using HTTP [RFC7230], HTTPS [RFC2818], or TCP [RFC793].
The SQL Server Analysis Services base messaging protocol, which includes support for tabular mode at compatibility levels 1100 and 1103, is defined in [MS-SSAS]. The SQL Server Analysis Services Tabular protocol extends the SQL Server Analysis Services protocol to add support for messages that apply to databases in tabular mode at compatibility levels 1200 and higher.<1>
