System and method for event notification through a firewall

An inter-enterprise event notification system, comprising:

• a first enterprise computer system comprising:
• a first enterprise firewall operable to protect data associated with the first enterprise computer system;
• a register operable to associate predefined data criteria with a second enterprise application according to a data access framework in response to a subscription request from the second enterprise application, the second enterprise application executing at a second enterprise computer system comprising a second enterprise firewall operable to block communication of at least some events to the second enterprise application;
• and
• an event manager operable to generate an event for the second enterprise application in response to the presence of data satisfying the predefined data criteria;
• and
• a proxy at the first enterprise computer system operable to provide the second enterprise application access to the first enterprise computer system through the first enterprise firewall, the second enterprise application operable to connect to the first enterprise computer system using the proxy to receive the event without establishing a proxy at the second enterprise computer system.

An event notification system, comprising:

• an internal firewall separating a server and a client, the internal firewall operable to block communication of at least some events from the server to a client application of the client;
• the server comprising a register operable to associate predefined data criteria with the client application according to a data access framework in response to a subscription request from the client application;
• the server further comprising an event manager operable to generate an event for the client application in response to the presence of data satisfying the predefined data criteria;
• and
• the client application operable to connect to the server to receive the event without establishing a client-side proxy.

An inter-enterprise event notification system, comprising:

• an internal firewall separating a first enterprise computer system from a second enterprise computer system, the internal firewall operable to block communication of at least some events from the first enterprise computer system to an application of the second enterprise computer system;
• the first enterprise computer system operable to associate predefined data criteria with the second enterprise application according to a data access framework and in response to a subscription request from the second enterprise application;
• the first enterprise computer system further operable to generate an event for the second enterprise application in response to the presence of data satisfying the predefined data criteria;
• and
• the second enterprise application operable to connect to the first enterprise computer system to receive the event without establishing a proxy at the second enterprise computer system.

A method of providing event notification through a firewall operable to block communication of at least some events from a server to a client, comprising:

• according to a data access framework, associating predefined data criteria at the server with a client application of the client in response to a subscription request from the client application;
• generating an event for the client application in response to the presence of data satisfying the predefined data criteria;
• and
• communicating the event to the client application when the client application connects to the server to receive the event, the communication performed without establishing a client-side proxy.

A method of providing event notification through a firewall operable to block communication of at least some events from a first enterprise computer system to a second enterprise computer system, comprising:

• according to a data access framework, associating predefined data criteria at the first enterprise computer system with a second enterprise application of the second enterprise computer system in response to a subscription request from the second enterprise application;
• generating an event for the second enterprise application in response to the presence of data satisfying the predefined data criteria;
• and
• communicating the event to the second enterprise application when the second enterprise application connects to the first enterprise computer system to receive the event, the communication performed without establishing a proxy at the second enterprise computer system.
