During its startup dedcd module tries to communicate with dnmmsd module from which it will be received information needed to run collections, and with damsnmpdaud module to which it will be sent collected data. When dedcd can't connected with any modules, it will try to connect with it every some period of time. It does the same if a connection is interrupted. In a case of a connection lack with dnmmsd module no collections are carried on.

An important property of dedced is a fact, that it automatically reacts on all changes in Network Information Database managed by dnmmsd module. So, data from newly discovered devices and network interfaces will be automatically collected, and collections will be stopped for devices deleted form Network Information Database and i.e. network interfaces marked as deleted through dnmmsd module.

Almost all configured information concerning collected device parameters, a frequency of sending messages to them, a graph coloring etc. come from Network Information Database and they can be configured with a level of Network Management Map application.

Results of dedcd work are shown the best through David system Web interface.
