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 using HTTP [RFC7230], HTTPS [RFC2818], or TCP [RFC793].

This protocol uses SOAP over HTTP or HTTPS, as shown in the following layering diagram:
