X/Open XA Architecture
In the X/Open XA architecture, a transaction manager or transaction processing monitor (TP monitor), coordinates the transactions across multiple resources such as databases and message queues. Each resource has its own resource manager. The resource manager typically has its own API for manipulating the resource, for example the JDBC API used by relational databases. In addition, the resource manager allows a TP monitor to coordinate a distributed transaction between its own and other resource managers. Finally, there is the application which communicates with the TP monitor to begin, commit or rollback the transactions. The application also communicates with the individual resources using their own API to modify the resource.

Famous quotes containing the words open and/or architecture:
“The novelist is required to open his eyes on the world around him and look. If what he sees is not highly edifying, he is still required to look. Then he is required to reproduce, with words, what he sees.”
—Flannery O’Connor (1925–1964)
“I don’t think of form as a kind of architecture. The architecture is the result of the forming. It is the kinesthetic and visual sense of position and wholeness that puts the thing into the realm of art.”
—Roy Lichtenstein (b. 1923)
