IHE ACDC Transactions

Transactions

This Volume II supplement describes the ACDC Transactions in detail. The ACDC Profile uses the following 4 IHE Transactions.

1. [PCC-71] Query Artifact
2. [PCC-72] Request Assessment
3. [PCC-73] Report Assessment

Understanding the IHE Transaction Model

Transaction descriptions are provided in Section 3. In each transaction description, the actors, the roles they play, and the transactions between them are presented as use cases. The generic IHE transaction description includes the following components:

Scope

A brief description of the transaction.

Use case roles

Textual definitions of the actors and their roles, with a simple diagram relating them, e.g.,

Referenced Standards

The standards (stating the specific parts, chapters or sections thereof) to be used for the transaction.

Interaction Diagram

A graphical depiction of the actors and messages that support the transaction, with related processing within an actor shown as a rectangle and time progressing downward, similar to the following

The interaction diagrams used in the IHE IT Infrastructure Technical Framework are modeled after those described in Grady Booch, James Rumbaugh, and Ivar Jacobson, The Unified Modeling Language User Guide, ISBN 0-201-57168-4. Simple acknowledgment messages are often omitted from the diagrams for brevity. One or more messages may be required to satisfy a transaction. Each message is represented as an arrow starting from the actor initiating the message.

Message definitions

descriptions of each message involved in the transaction, the events that trigger the message, its semantics, and the actions that the message triggers in the receiver.
