 The SQL Server transport implements a message queuing mechanism on top of [Microsoft SQL Server](https://www.microsoft.com/en-us/sql-server/). It provides support for sending messages using SQL Server tables. It does **not** make use of a [service broker](https://technet.microsoft.com/en-us/library/ms166104.aspx).
