One of the powerful concepts that help in organization and management of information is classification. This concept is applicable wherever we deal with some pieces of information. In the field of computer software, classification is best fitted into Information Systems, in which, there are lots of different objects or entities. Nebras Classifier is a distributed model-view component developed to perform such information handling using both COM and CORBA communication facilities. In this component, model has a hierarchical structure capable of storing multiple instances of domain CORBA objects in its nodes and has facilities to perform special queries on this structure. The view is a graphical representation for this model. A third party named Semantic Engine that is domain dependent, may be used in interaction with these two parts using proxy design pattern to perform required feasibility checks or domain dependent actions on the classifier. Nebras Classifier can be embedded into almost all object oriented software systems. In order to be classifiable, every class of objects must support a specific interface exhibited by this component.
In this demonstration we are going to present:
