Server synchronisation was then illustrated in a diagram. Dimitrious replied that the run time repositories are distinct entities. In reply, Dimitrios said that the system configuration defines the maximum latency so one is sure that events occur at right time. A general purpose to store events is a good thing. A diagram showing application construction was shown.
Events allow distributed debugging.
Logging for charging and fraud detection. The approach is to store events in the same service, not elsewhere. Retrieval via ODMG compatible data model familiar to DB users with addition of special temporal operators to handle temporal event mining. A complex system example was shown in a diagram supporting automatic minuting, mobility and disconnected operation. Classification of events allows retrieval on a class of intervals.
