Extending object-oriented databases for fuzzy information modeling

摘要

In this paper, based on possibility distribution and the semantic measure of fuzzy data, we introduce an extended object-oriented database model to handle imperfect as well as complex objects in the real world. Some major notions in object-oriented databases such as objects, classes, objects–classes relationships, subclass/superclass, and multiple inheritances are extended under fuzzy information environment. A generic model for fuzzy object-oriented databases and some operations are hereby developed in the paper.
