With MOM, messages sent to the client are collected and stored until they are acted upon, while the client continues with other processing.

; Enterprise messaging
: An [[enterprise messaging system]] is a type of middleware that facilitates message passing between disparate systems or components in standard formats, often using [[XML]], [[SOAP]] or [[web services]].  As part of an enterprise messaging system, [[message broker]] software may queue, duplicate, translate and deliver messages to disparate systems or components in a messaging system.

; Enterprise service bus
: [[Enterprise service bus]] (ESB) is defined by the [[Burton Group]]<ref name="ms-on-esb">{{Cite web|url=http://msdn.microsoft.com/en-us/library/aa475433(BTS.10).aspx|title=Microsoft on the Enterprise Service Bus (ESB)|date=August 2005|quote=The ESB label simply implies that a product is some type of integration middleware product that supports both MOM and Web services protocols.}}</ref> as "some type of integration middleware product that supports both [[message-oriented middleware]] and [[Web services]]".
