RTR Continuous Computing Concepts

RTR Continuous Computing Concepts

RTR provides a continuous computing environment that is
particularly valuable in financial transactions, for example
in banking, stock trading, or passenger reservations systems.
RTR satisfies many requirements of a continuous computing
environment:

Reliability

Failure tolerance

Data and transaction integrity

Scalability

Ease of building and maintaining applications

Interoperability with multiple operating systems

RTR additionally provides the following capabilities, essential in
the demanding transaction processing environment:

Flexibility

Parallel execution at the transaction level

Potential for step-by-step growth

Comprehensive monitoring tools

Management station for single console system management

WAN deployability

RTR also ensures that transactions have the ACID properties.
A transaction with the ACID properties has the following
attributes:

Atomic

Consistent

Isolated

Durable

For more details on transactional ACID properties, see the
discussion later in this document, and in the RTR Application
Design Guide
