HL7 Accelerator Overview
As you might know, the BizTalk Accelerator for HL7 offers a great deal of enhanced messaging capabilities for the healthcare industry. Although it is offered as a separate download, it comes with the license of BizTalk.

The figure below shows all of the project templates installed through the installation process of…
