Abstract

In the present work we attempt to extension an object oriented data model to: 1) describe fuzzy objects with a new attribute type which we call a fuzzy complex attribute, where a complex attribute can be either calculated (i.e., its value is calculated from values of other attributes) or aggregated (i.e., it is composed by a set of attributes) and all the manipulated values can be fuzzy; 2) extend the retrieval process with the new attribute type in order to allow more flexibility in queries. The approach we propose is illustrated by a real example in human resources management
