Imagine we got something like an industrial process to control.
A process could be a manufacturing machine, a steel-mill or a power-grid.
But it could also be a railroad security system or a computer aided
dispatching system. All these processes have one thing in common
- if worse comes to worse there could be thousands of messages
arriving per second. Of course not as a regular load but in
special situations. Then thousands of messages, signals or technically
spoken telegrams, are arriving at the control station and need to
be processed. No need to say that this type of processing cannot
be handled directly in a relational database.
But does this mean that these systems cannot incorporate relational
databases?
Of course THEY CAN - by using a memory resident shared real-time
database that is synchronized with the ORACLE database - the Real
Time Database (RtDB).
RtDB is sitting between the process
and the relational database making sure that the process can handle
database operations timely while at the same time synchronizing
all data with Oracle. You can think of it as a cache between the
process and Oracle, but it is of course much more sophisticated.
For an inside look how RtDB works

Description to see an example.
How can my application
use these features?
