Enterprise computer system
A scalable enterprise computer system having the capability to provide transaction security as well as providing subscription filtering is described. As a method of transacting an event in the enterprise computer system a connection with an information broker by the publishe established after which it is determined if the event registered with the information broker. Next, a subscription corresponding to the registered event by a subscriber is accepted by the information broker, after which a platform neutral event is created that is then populated with event content which is then published to and received by the information broker.

(a) establishing a connection with an information broker by a publisher;
(b) determining if the event is registered with the information broker;
(c) accepting a subscription corresponding to a registered event by a subscriber
(d) creating a platform neutral event;

(f) publishing the populated event to the information broker by the publisher; and
(g) receiving the published event by the information broker
wherein an event is a business event created by one resource and is of interest to another.
2. A method as recited in claim 1 , further comprising:
(h) determining an event type that corresponds to the received event by the information broker;
(i) determing whether or not the event is a valid event based in part upon the event type;
(j) determining whether or not the connection is valid; and

(l) determining whether or not the event type matches the subscription;
(m) determining whether or not an event security level is verified when the event type matches the subscription;
(n) determining whether or not an event content matches a content filter when the event security level is verified and when the event type matches the subscription; and
(o) determining whether or not an event authorization is valid when the event security level is verified and when the event type matches the subscription such that when the event authorization is valid, the event is the valid event.
4. A method as recited in claim 1 , wherein the enterprise computer system includes a plurality of interconnected information brokers.

7. A method as recited in claim 1 , wherein the information broker includes a preprocessor suitably arranged to perform (h)–(k).
8. A method as recited in claim 7 , wherein the information broker further includes a preprocessor queue that couples the preprocessor to the content filter.
