Summary

The object selection problem requires the evaluation of the fitness of a candidate server object to a certain task on the basis of the information about its behaviour attached to it by a classification model. Many distributed O-O execution environments store such information in a Trader system which can be browsed or queried by client objects. In this paper a fuzzy data model is proposed as the basis of the design of a Trader system. A fuzzy query algebra is described, allowing for specifying operator definitions (and, therefore, query execution mechanisms) at run time, on the basis of user-selected semantics.
