OpenTP1 Version 7 Description
In the X/Open DTP model, transaction processing is an interaction among:
The UAP specifies the contents of the transaction and directs a transaction manager to start or terminate a transaction. A transaction manager manages the transaction and coordinates the completion of a transaction across a set of resource managers. A resource manager manages a particular shared resource. A communication resource manager manages inter-application components. Figure 1-10 illustrates the relation among the components of the model and their interfaces.

The DTP models are composed of the following elements.
Manages resources concerning the communication between the systems.
Each element that composes a DTP model can be linked with the following interfaces.
Instructs update of resources from AP to RM. The API to RM contains an SQL.
The following shows RMs that can be used in OpenTP1.
Figure 1-11 shows the relationship between the X/Open DTP model and the OpenTP1 system.
