Automatic detection and removal of ineffective mutants for the mutation analysis of relational database schemas [PDF]

open access: yes, 2019
Data is one of an organization’s most valuable and strategic assets. Testing the relational database schema, which protects the integrity of this data, is of paramount importance. Mutation analysis is a means of estimating the fault-finding “strength” of

DSP: Schema Design for Non-Relational Applications

open access: yesSymmetry, 2020
The way a database schema is designed has a high impact on its performance in relational databases, which are symmetric in nature. While the problem of schema optimization is even more significant for NoSQL (“Not only SQL”) databases, existing modeling ...

Visualizing risk factors of dementia from scholarly literature using knowledge maps and next-generation data models

open access: yesVisual Computing for Industry, Biomedicine, and Art, 2021
Scholarly communication of knowledge is predominantly document-based in digital repositories, and researchers find it tedious to automatically capture and process the semantics among related articles. Despite the present digital era of big data, there is

Representing Non-Relational Databases with Darwinian Networks

open access: yesInternational Journal of Engineering Research and Applications, 2017
The Darwinian networks (DNs) are first introduced by Dr Butz to simplify and clarify how to work with Bayesian networks (BNs). DNs can unify modeling and reasoning tasks into a single platform using the graphical manipulation of the probability tables that takes on a biological feel.

A benchmark for online non-blocking schema transformations [PDF]

open access: yes, 2015
This paper presents a benchmark for measuring the blocking behavior of schema transformations in relational database systems. As a basis for our benchmark, we have developed criteria for the functionality and performance of schema transformation ...

Towards an Efficient Evaluation of General Queries [PDF]

open access: yes, 1989
Database applications often require to evaluate queries containing quantifiers or disjunctions, e.g., for handling general integrity constraints. Existing efficient methods for processing quantifiers depart from the relational model as they rely on ...
