Suresh K. Damodaran, Pedro A. Colon-Hernandez
TL;DR
This paper introduces Address Expressions (A-Expressions), a technique for embedding ontological references in NoSQL queries to enhance their portability across different physical data store implementations, demonstrated with MongoDB and evaluated for performance.
Contribution
It presents a novel method for embedding ontological expressions in NoSQL queries, improving portability across diverse data store implementations.
Findings
A-Expressions improve query portability across NoSQL systems.
Implementation over MongoDB shows practical feasibility.
Preliminary performance assessment indicates acceptable overhead.
Abstract
A significant barrier to the portability of queries across di- verse physical implementations of large data stores, espe- cially NoSQL data stores, is that the queries reference the physical storage attributes, such as the table and column names. In this paper, we describe a technique for embed- ding ontological expressions called Address Expressions, or A-Expressions, in NoSQL queries to improve their portability across diverse physical implementations. We discuss an implementation of such queries over a MongoDB data store of the Enron email corpus with examples, and conduct a preliminary performance assessment.
