A Dynamic Foundational Architecture for Semantic Web Services
(Kluwer Academic Publishers; Springer Science+Business Media, Inc., 2005-03)
The combination of Web services and ontologies is gaining momentum as the potential silver bullets for tomorrow’s Web, i.e., the Semantic Web. We propose an architectural foundation for managing semantic Web services in ...
Evolutionary techniques for updating query cost models in a dynamic multidatabase environment
(Springer-Verlag, 2004-05)
Deriving local cost models for query optimization in a dynamic multidatabase system (MDBS) is a challenging issue. In this paper, we study how to evolve a query cost model to capture a slowly-changing dynamic MDBS environment ...
Optimizing complex queries based on similarities of subqueries
(Springer-Verlag, 2005-09)
As database technology is applied to more and more application domains, user queries are becoming increasingly complex (e.g. involving a large number of joins and a complex query structure). Query optimizers in existing ...
An object-oriented approach to Computer Integrated Systems
(Kluwer Academic Publishers; Springer Science+Business Media, 1996-08)
In recent years computers have been incorporated into large scale systems such as nuclear plant, flight control, and manufacturing systems. Such Computer Integrated Systems (CIS) normally consist of heterogeneous subsystems. ...
The Algebraic Framework for Object-Oriented Systems
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-09)
Category Theory is introduced as the mathematical model for object-oriented systems which are distributed, heterogeneous, real-time, embedded, and open-ended. Each object can be represented as an algebra. A collection of ...
Cost Estimation for Queries Experiencing Multiple Contention States in Dynamic Multidatabase Environments
(Springer-Verlag London Limited, 2003-02)
Accurate query cost estimation is crucial to query optimization in a multidatabase system. Several estimation techniques for a static environment have been suggested in the literature. To develop a cost model for a dynamic ...
Spatial Color Indexing Using Rotation, Translation, and Scale Invariant Anglograms
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-12)
As color plays an essential role in image composition, many color indexing techniques have been studied for content-based image retrieval. This paper examines the use of a computational geometry-based spatial color indexing ...
A synthetic approach to the design of information-systems software
(Elsevier, 1989-07)
This paper presents an approach to the design of information-systems software in which alternative designs can be created, as necessary, until specified requirements are met and specific objectives achieved. This approach ...
Solving Local Cost Estimation Problem for Global Query Optimization in Multidatabase Systems
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-10)
To meet users' growing needs for accessing pre-existing heterogeneous databases, a multidatabase system (MDBS) integrating multiple databases has attracted many researchers recently. A key feature of an MDBS is local ...
