The Interface Engine is a full-featured environment for all your HL7® needs


The Interface Engine (TIE) is a complete middleware package focused on implementing the healthcare information exchange standards defined by HL7 International, both Version 2.x messaging and Clinical Documents (CDA). TIE (formerly known as HL7Connect) is both powerful and easy to use. TIE manages messages and documents, and exchanges them using a wide variety of transport mechanisms. In addition, you can build integration using VBScript or Javascript, or any DotNet or COM capable language, or use TIE from your own application.
