Fuzzy object-oriented databases model with hedge algebra based semantics.

A Query Algebra for Object-Oriented Databases

We deene an algebra which synthesizes relational query concepts with object-oriented databases. The algebra fully supports abstract data types and object identity while providing associative access to objects, including a unique join capability. The operations take an abstract view of objects and access typed collections of objects through the public interface deened for the type. The algebra s...

The Semantics of Object-Oriented Databases

Transform More Semantics from Relational Databases into Object-Oriented Databases

OSAM* is an object-oriented semantic data model for advanced applications such as CIMS, knowledge processing system[l2]. For its strongly modeling capability of both object-oriented data models and semantic data models, OSAM*-based h&zogeneous distPribnted dat,abnse systems have been developed such as IMDAS[8] and CIMBASE[14]. In the two syaterns, OSAM* is used as the common data model, and two...

Conceptual Modeling for Fuzzy Object Oriented Databases

This technological era is raising new challenges towards the storage and management of data, that is getting more complex and imprecise with the evolution of utilization of computer engineering in most of the areas of society. To confront the arising challenges, database researchers has introduced fuzzy object oriented databases, by blending the concepts of database management system, object or...

Fuzzy and Probabilistic Object-Oriented Databases

For modeling real-world problems and constructing intelligent systems, integration of different methodologies and techniques has been the quest and focus of significant interdisciplinary research effort. The advantages of such a hybrid system are that the strengths of its partners are combined and complementary to each other’s weakness. In particular, object orientation provides a hierarchical ...
