System of aggregating servers

A system of aggregating servers, comprising:

• a first aggregating server configured to establish a session for communicatively linking with at least one first system to be aggregated;
• at least a second aggregating server configured to establish a session communicatively linking with at least one second system to be aggregated,
• wherein each of the first aggregating server and the second aggregating server comprises:
• an information model server configured to provide an aggregated information model, which aggregates the information models of each system to be aggregated, which are coupled for communication to the system of aggregating servers:
• a database configured to store the structured data of the systems to be aggregated according to an aggregated information model, which is related to the respective systems to be aggregated;
• a device connection manager configured for controlling a policy for establishing a session of the related systems to be aggregated with the related aggregating server;
• and
• a device client configured to enable and run a session with the systems to be aggregated, and
• wherein the first aggregating server and the second aggregating server are configured to:
• replicate mutually structured data provided by the first system to be aggregated and/or the second system to be aggregated to provide access to the structured data of the respective systems to be aggregated for the first aggregating server and the second aggregating server;
• and
• coordinate the respective sessions of the system of aggregating servers with the at least first system to be aggregated and/or the at least second system to be aggregated to prevent improper access to the at least first system to be aggregated and/or the at least second system to be aggregated.
