Main Memory Oriented Optimization of 00 Queries Using Typed Datalog with Foreign Predicates
Object-oriented DBMS’s (OODB’s) have created a demand for relationally complete, extensible, and declarative object-oriented (00) query languages. Until now,...
A Normalization Framework for Multimedia Databases
We present a normalization framework for the design of multimedia database schemas with reduced manipulation anomalies. To this end,...
Measuring the effects of data distribution models on performance evaluation of distributed database systems
The effect of simplistic assumptions about the data distribution and replication in a system on performance measures and the...

Converting a Fuzzy Data Model to an Object-Oriented Design for Managing GIS Data Files
A fuzzy entity relationship diagram (ERD) data model for managing information about sets of related data files was converted...
Constraint analysis: a design process for specifying operations on objects
A design process for an object-oriented database design environment, known as constraint analysis, is presented. Given the increased level...
Specifying and Enforcing Association Semantics via ORN in the Presence of Association Cycles

A History Approach of Automatic Relationships Establishment for VLSI Design Database
We propose a novel data management paradigm that incrementally and transparently constructs the relationships among VLSI design objects. This...
Database Design Principles for Placement of Delay-Sensitive Data on Disks
We investigate design principles for placing striped delay-sensitive data on a number of disks in a distributed environment. The...
