Description
Summary:Flexible querying provides new interrogation tools that enable the user to express preferences inside requirements and priorities inside compound queries. The answers are qualified and presented as a set of discriminated elements according to their degree of adequation. The objective of our work is to define a flexible query language for an object-oriented database and to provide a general framework on which applications can fully exploit the graduality associated with their processing tools. In this paper, we focus specifically on the study of bags.
