Database Slicing on Relational Databases

open access: yesActa Cybernetica, 2014
Many software systems today use databases to permanently store their data. Testing, bug finding and migration are complex problems in the case of databases that contain many records. Here, our method can speed up these processes if we can select a smaller piece of the database (called a slice) that contains all of the records belonging to the slicing ...

The Telomerase Database [PDF]

open access: yesNucleic Acids Research, 2007
Telomerase is a ribonucleoprotein enzyme that extends DNA at the chromosome ends in most eukaryotes. Since 1985, telomerase has been studied intensively and components of the telomerase complex have been identified from over 160 eukaryotic species. In the last two decades, there has been a growing interest in studying telomerase owing to its vital role

The CATH database [PDF]

open access: yesHuman Genomics, 2010
The CATH database provides hierarchical classification of protein domains based on their folding patterns. Domains are obtained from protein structures deposited in the Protein Data Bank and both domain identification and subsequent classification use manual as well as automated procedures. The accompanying website (www.cathdb.info) provides an easy-to-

Algebraic Databases

open access: yesTheory and Applications of Categories, 2017
Databases have been studied category-theoretically for decades. The database schema -- whose purpose is to arrange high-level conceptual entities -- is generally modeled as a category or sketch. The data itself, often called an instance, is generally modeled as a set-valued functor, assigning to each conceptual entity a set of examples.

Subjective databases

open access: yesProceedings of the VLDB Endowment, 2019
Online users are constantly seeking experiences, such as a hotel with clean rooms and a lively bar, or a restaurant for a romantic rendezvous. However, e-commerce search engines only support queries involving objective attributes such as location, price, and cuisine, and any experiential data is relegated to text reviews.
