Coping with Events in Temporal Relational Databases
Event relations are used in many temporal relational database approaches to represent facts occurring at time instants. However, to...
Irregular Indeterminate Repeated Facts in Temporal Relational Databases
Time is pervasive of reality, and many relational database approaches have been developed to cope with it. In practical...
Ancestor Controlled Submodule inclusion in Design Databases
A paradigm is proposed for representing hierarchically specified design data in CAD database systems where there are to be...
A Survey of Languages for Specifying Dynamics: A Knowledge Engineering Perspective
During the last years, a number of formal specification languages for knowledge-based systems has been developed. Characteristics for knowledge-based...
The Role of Polymorphic Reuse Mechanisms in Schema Evolution in an Object-Oriented Database
A seamless approach to the incremental design and reuse of object-oriented methods and query specifications is presented. We argue...
Part-Whole Relationship Categories and Their Application in Object-Oriented Analysis
Part decomposition and, conversely, the construction of composite objects out of individual parts have long been recognized as ubiquitous...
A comparative study of various nested normal forms
As object-relational databases (ORDBs) become popular in the industry, it is important for database designers to produce database schemes...
Towards the Correctness and Consistency of Update Semantics in Semantic Database Schema
This paper discusses a paradigm and prototype system for the design-time expression, checking, and automatic implementation of the semantics...
System-Guided View Integration for Object-Oriented Databases
View integration refers to the activity of merging the locally developed user-oriented views or schemas for a given environment...
An Object-Oriented Database System Jasmine: Implementation, Application, and Extension
New applications such as engineering tasks require complex object modeling, integration of database and programming facilities, and extensibility. We...
