OpenTP1 provides online transaction processing^# in a distributed processing environment.

OpenTP1 supports open systems. It complies with the X/Open Distributed Transaction Processing model for distributed processing. OpenTP1 systems can communicate with other open systems.

Organizations can use OpenTP1 to develop and manage online transaction processing systems. These systems can work in OpenTP1 client/server configurations, and can communicate with non-OpenTP1 systems.

During online transaction processing, OpenTP1 can prevent, detect, and recover from errors and failures to a degree that was previously possible on closed mainframe systems or restricted database management systems only.

Figure 1-1 shows the features of OpenTP1.

In data communications, the processing must be divided into individual steps and the validity of the result clearly determined. Each step at which the result is judged true or false is known as a transaction.
