The master server or administration server is the main server in the network topology which contains the database. It is responsible for answering requests from the console and executing the appropriate database communication. It receives and stores all information and data sent by the client agents and sends requests for additional information when necessary through the first-level relays. The master server database is an object model database system in which each network or system component is modeled by corresponding model objects. It operates in real time and reacts to changes in the real network and systems components by updating and changing the corresponding objects in the database. The BMC Client Management console connects to the master to display the collected data on the screen.
