Abstract

An embodiment relates generally to a method of updating data. The method includes providing for a plurality of components, where each component is associated with a respective web page. The method also includes providing for a subset of components from the plurality of components, where the subset of components subscribes to an event. The method further includes publishing a notification message in response to the event occurring and retrieving the event by the subset of components.

Claims

1. A method for updating data, the method comprising:

subscribing each component of a set of components to at least one topic associated with a set of events, wherein each component of the set of components is associated with at least one web page;

receiving a particular event from the set of events relating to a particular topic from the at least one topic;

providing, via a bus, a notification message to a subset of the set of components subscribed to the particular topic; and

providing, via the bus, the particular event to the subset of the set of components.

2. The method of claim 1, further comprising:

receiving the particular event at a manager module; and

storing the particular event.

5. The method of claim 1, wherein each component of the subset of components is configured to monitor the bus for the notification message.

6. The method of claim 1, further comprising:

maintaining a list of the at least one topic associated with the set of events on a manager module.

3. (canceled)

4. (canceled)

7. A system for transferring information, the system comprising:

a message bus;

a plurality of web pages, each web page having at least one component of a plurality of components, wherein a subset of the components are coupled to the message bus, and wherein the subset of components are subscribed to at least one topic associated with a set of events;

a memory having computer-executable instructions that provide a manager module coupled to the message bus, wherein the manager module is configured to receive an event from the set of events over the message bus, to buffer the event, to broadcast a notification message associated with the event on the message bus, and to send the event to the subset of components subscribed to the at least one topic associated with the event; and

a processor configured to execute the instructions.

8. The system of claim 7, wherein each component of the subset of components is configured to monitor the message bus for at least one notification message associated with an event from the set of events.

9. The system of claim 8, wherein each component in the subset of components is configured to retrieve the event from the manager module in response to receiving the least one notification message associated with the event.

10. The system of claim 9, wherein each component in the subset of components is configured to process the event and data contained in the event.

11. The system of claim 7, further comprising:

an application web page comprising a server side component and a browser component, wherein the browser component is coupled to the message bus.

12. The system of claim 11, wherein the server side component is configured to publish a selected event to the browser component.

13. The system of claim 12, wherein the browser component is configured to publish the selected event to the manager module.

14. The system of claim 11, wherein the browser component is configured to publish an event to the manager module and to update the server side component.

15. The system of claim 11, wherein a selected one of the at least one component of a web page of the plurality of web pages is configured to publish a second event to the manager module.

16. A system for transferring information, the system comprising:

a message bus;

a plurality of web pages, each web page having at least one component of a plurality of components, wherein a subset of the components are coupled to the message bus, and wherein the subset of components are subscribed to at least one topic associated with a set of events;

an application web page comprising a server side component and a browser component, wherein the browser component is coupled to the message bus;

a memory having computer-executable instructions that provide a manager module coupled to the message bus, wherein the manager module is configured to receive an event from the set of events over the message bus, to buffer the event, to broadcast a notification message associated with the event on the message bus, and to send the event to the subset of components subscribed to the at least one topic associated with the event; and

a processor configured to execute the instructions, wherein

a selected one of the at least one component of a web page of the plurality of web pages is configured to publish a second event to the manager module; and

the browser component is configured to subscribe to the second event and to monitor for a notification message associated with the second event.

17. The system of claim 16, wherein the browser component retrieves the second event from the manager module in response to receiving the notification message associated with the second event.

18. The system of claim 17, wherein the browser component is configured to update the server side component with associated information from the second event.
