In this paper, we propose a mechanism for the dynamic monitoring of events in the heterogeneous distributed databases. The suggested monitoring tools are implemented using the events sensors that are operated on the basis of direct access to the memory, which is allocated by the operating system for the database. There is suggested the event monitoring system in the heterogeneous databases, that is based on the developed model, which is based on event monitoring sensors. The specialty of the model is that it differs from the existing ones by the use of vector-matrix equations to provide operative solutions as respond to the security incidents in database. Also, there is developed the algorithm of the functioning of the events monitoring system in the distributed databases based on the events sensors. It is shown that the monitoring mechanisms on the basis of the proposed monitoring model allow dynamically process the monitoring information and allow to reduce the probability of intrusion and the errors occurrence in the database.
