The BTAHL7 End-to-End Tutorial provides you with detailed steps to facilitate business processes in a subscriber and publisher scenario. This scenario is a situation in which a publisher, for example, an Admissions Discharge and Transfer system sends a message to specific subscribers.

The message routes to the BTAHL7 Interface Engine, which in turn receives, processes, validates, reformats, and then routes the message to the subscribers. The subscribers in this scenario are a Hospital Information System and a Pharmacy System.

This scenario uses both File and Minimal Lower Layer Protocol (MLLP) adapter types. The publisher does not need to be aware of the subscribers, and the BTAHL7 Interface Engine sends an appropriate acknowledgement to the publisher after processing the message.

The BTAHL7 Interrogative Tutorial provides you with detailed steps for implementing a query-response system between sub-systems within an organization. In this scenario, a line-of-business (LOB) application in the Admissions, Discharge, and Transfer system sends a query to the Hospital Information System to obtain patient lab results. After the Hospital Information System receives the query, it sends the requested data back to the system that issued the query.

This scenario uses MLLP as the transport protocol for all messages, including acknowledgments.

The BTAHL7 Enrichment Tutorial provides you with detailed steps to solve a particular business problem: the message-enrichment scenario. The message-enrichment scenario is a situation in which you have to add to, or enrich, a message that is not HL7-compliant and/or is incomplete. This situation can occur with an application, such as a patient-registration application, or when you are populating a message with XML data from Microsoft SQL Server.

In the message enrichment scenario, you capture the messages with BTAHL7, and provide any missing data, for example, from a patient-records database. You then convert the message and send it to a laboratory, insurance, or any legacy line-of-business (LOB) application using the MLLP adapter.

The BTAHL7 Batching Tutorial provides you with detailed steps to receive and send batched messages. Batching involves receiving and/or sending a group of individual messages (or acknowledgments) as a single composite message.

BTAHL7 supports the following three message batching scenarios:

• Fragmented inbound batch. In this scenario, BTAHL7 receives an HL7 message batch, and then routes the individual messages to the destination system.
  
  
• Batch in/batch out. BTAHL7 receives an HL7 message batch, verifies the individual messages within the batch, and then routes the message batch to the destination system.
  
  
• Create batch (or outbound batching). BTAHL7 receives individual messages and batches them before routing them to the destination system.
