Fuzzy Object Oriented Database versus FRDB for Uncertainty Management

Abstract

It is impossible to capture all of the semantics of real world information and to model it in a perfect way. Uncertain information being lacking information, individual interpretation of knowledge is taken into account. Most widely used relational model faced much difficulty to handle complex data requirements. The size of databases and their changing composition such as graphics, video and sound, as well as numbers and text invited a reorganization of existing information systems. Object oriented database draw their strength from graphical user interfaces, advanced data management capabilities and powerful modeling techniques. So in order to deal with inexactness fuzzy techniques have been extensively integrated with more advanced object oriented database system which is capable to represent and manipulate the complex objects as well as complicated and uncertain relationship exiting among them. In this paper uncertainty using Fuzzy Object Oriented Database and Fuzzy Relational Data Base is illustrated.

Analysis of Fuzzy Query Processing and Optimization in Fuzzy Object Oriented Database

“…Accordingly, in the fuzzy OODB [7][8] [9], an object belongs to a class with a membership degree of [0, 1] and a class is the subclass of another class with degree of [0, 1] too [9]. In the OODB, the specification of a class includes the definition of ISA relationships, attributes and methods implementations.…”
