4. 7.4 ICDE Solution

5. 7.4.1 Relevant Architectural Patterns The following architecture patterns are used in the design: –Three-tier: Third party tools are clients, communicating with the API implementation in the middle tier, which queries the ICDE v2.0 data store. –Publish-subscribe: The middle tier contains a publish- subscribe capability. –Layered: Both the client and middle tier employ layers internally to structure the design.

6. 7.4.2 Architecture Overview Event notification is achieved using a publish-subscribe infrastructure based on the Java Messaging Service (JMS).
