Exact and Approximate Algorithms for the Index Selection Problem in Physical Database Design
The index selection problem (ISP) is an important optimization problem in the plhysical design of databases. The aim of...
Valid-Time Indeterminacy in Temporal Relational Databases: Semantics and Representations
Valid-time indeterminacy is “don’t know when” indeterminacy, coping with cases in which one does not exactly know when a...
Conceptual transaction modeling
Transaction modeling, which involves capturing the dynamic properties of an organization, is seen as a necessary component in data...
Rewriting Rules to Permeate Complex Similarity and Fuzzy Queries within a Relational Database System
In recent years, the availability of complex data repositories (e.g., multimedia, genomic, semistructured databases) has paved the way to...
A General Theory for Evolving Application Models
In this article we provide a general theory for evolving information systems. This theory makes a distinction between the...
NoSE: Schema Design for NoSQL Applications
Database design is critical for high performance in relational databases and a myriad of tools exist to aid application...
Materialization
A new data abstraction, called Materializdion, is introduced to model a situation that occurs frequently in the real world...
A Graph-Oriented Object Database Model
A graph-oriented object database model (GOOD) is introduced as a theoretical basis for database systems in which manipulation as...
Deductive Entity Relationship Modeling
We present an entity relationship oriented model, which essentially includes the notion of class, together with different types of...
Semantic Abstractions in the Multimedia Domain
Information searching by exactly matching content is traditionally a strong point of machine searching; this is not, however, how...
