In this tutorial, you will step through the process of setting up an Iguana channel that will do the following:

• Accept HL7 messages from the network;
• Extract data from these messages;
• Insert this data directly into a database.

	You can view a video that shows how to perform these tasks. To view this video, follow this link: Reading HL7 Messages Into a Database.

LLP is the standard way of transmitting HL7 messages over a network. You will be creating a connection that has an LLP Listener component as the source and a To Database component as the destination.

The objective of this tutorial for Iguana is to get patient demographics from HL7 messages and into a database. You will start by setting up a simple interface to handle a standard patient update (ADT^A04) HL7 message. Once you have your interface working for this type of message, some new requirements will be introduced to illustrate how an interface might evolve and expand over time.
