UML Profile Definition for Dealing with the Notification Aspect in Distributed Environments1

The CORBA Notification Service allows objects developed under this platform to communicate asynchronously. Nevertheless, the use of this service at implementation level implies a strong coupling between service and objects which use it. This coupling is due to the mixing of code. This mixing of code appears when we deal with two different aspects in the same object: event asynchronous communication and core functionality of the object. The use of aspect-oriented techniques let us avoid this problem whereas the extraction of this tangled and scattered code. In this paper, we propose the definition of an UML profile for dealing with the Event Notification Aspect in Corba distributed environments. This profile simplifies the application of this asynchronous communication. So we will have the event notification details perfectly separated from the basic functionality of the object details at design level. Finally, the use of this profile facilitates the generation of code regarding to the notification aspect. This code will be subsequently integrated with the objects which take part of the communication.
