Database network connectivity product
First Claim
1. A method of connecting a data base to a publisher/subscriber network, so that the data base can publish events to the network, the method comprising the steps, performed by a data processing system, of:
- providing a link so that the data base can communicate with a data base connector computer program by way of a transaction monitor computer program;
setting up the data base connector as a publisher in the network, wherein the publisher publishes events of a first event type;
receiving input, from the transaction monitor that a user has altered data in the data base;
receiving input from the transaction monitor indicating that the user has committed the data alteration; and
publishing, by the data base connector, in accordance with the input from the transaction monitor that the data is committed, an event, having the first event type, to the network in accordance with the altered data.

Abstract
A method and apparatus for publishing and receiving events to a network. A plurality of "publisher" entities publish information and a plurality of "subscriber" entities request and use the information. Publishers and subscribers are connected to each other through a network. The network is a "store and forward" network whose routing is "content-based." The basic quanta of information is called an "event." Publishers publish events and subscribers subscribe to events that match criteria defined by the subscriber. Publication and subscription are performed asynchronously. Publishers and subscribers do not have direct knowledge of each other. The system receives a published event from a publisher and routes the event to all appropriate subscribers. Each subscriber is guaranteed to receive all events published on the system if, and only if, they match the subscription criteria specified by the subscriber. A legacy data base can be added to the network by way of a data base connector, which can be a publisher, a subscriber, or both.

3. A method of connecting a data base to a publisher/subscriber network, so that the data base can subscribe to types of events advertised on the network, the method comprising the steps, performed by a data processing system, of:
-
providing a link so that a data base connector computer program can communicate with the data base; setting up the data base connector as a subscriber in the network, wherein the subscriber subscribes to a first events of a first event type; receiving, by the data base connector, an event from the network, having the first event type; sending, by the data base connector, data in accordance with the received event to the data base; and committing, by the data base connector, the data in the data base. - View Dependent Claims (14, 15, 16, 17, 18)
