The Advantage of NoSQL Databases over SQL Databases [PDF]

open access: yesDatabase Systems Journal
This article highlights the advantages of NoSQL databases compared to traditional SQL (relational) databases. It argues that the database concept is often implicitly tied to relational models, overlooking non-relational databases’ potential in Big Data ...

A relation merging technique for relational databases [PDF]

open access: yes[1992] Eighth International Conference on Data Engineering, 2003
A merging technique for relational schemas consisting of relation-schemes, key dependencies, referential integrity constraints, and null constraints is presented. The author examines the conditions required for using this technique with relational database management systems that provide different mechanisms for maintaining null and referential ...

Extracting OWL ontologies from relational databases using data analysis and machine learning [PDF]

open access: yes, 2016
Extracting OWL ontologies from relational databases is extremely helpful for realising the Semantic Web vision. However, most of the approaches in this context often drop many of the expressive features of OWL.

The Interoperability Challenge in DFT Workflows Across Implementations

open access: yesAdvanced Intelligent Discovery, EarlyView.
Interoperability and cross‐validation remain major challenges in the computational materials science. In this work, we introduce a common input/output standard that enables internal translation across multiple workflow managers—AiiDA, PerQueue, Pipeline Pilot, and SimStack—while producing results in a unified schema.

Innovative Artificial Intelligence‐Assisted Systems for Social Science Research: Architecture Design and Applied Practice

open access: yesAI &Innovation, EarlyView.
ABSTRACT The rapid advancement of large language model (LLM) technology is profoundly transforming the practice of social science research. Scholarly discussions on Artificial Intelligence (AI)'s role in social science research can be organised into three levels: AI as a research tool, AI as a methodological infrastructure and AI as a quasi‐cognitive ...

Logical Querying of Relational Databases

open access: yesJournal of Economic Development, Environment and People, 2016
This paper aims to demonstrate the usefulness of formal logic and lambda calculus in database programming. After a short introduction in propositional and first order logic, we implement dynamically a small database and translate some SQL queries in ...
