In defense of graphs within graphs — and/or hypergraphs — For those of you familiar with FactEngine Query Language (FEQL), you may have noticed that every piece of data is considered as if it were a node in a graph database. Take the following FEQL query for instance: The FEQL query is asking to show…

A suitable counterexample to the notion that Object-Role Modeling is unambiguous — We take a model for a UoD (Universe of Discourse) where we model the data requirements to store information about Round the World Tickets for an Airline. The scenario is where a person outlines the cities and countries that they would like to visit, and where the data model captures…

Game Theory, Communications Theory and Formal Logic — The central thesis of my research is that formal logic may be considered under game theory and communications theory under what I call a Coherent Cooperative Game of Formal Logic. The metatheory is that a Coherent Cooperative Game of Formal Logic (CCGFL) adequately describes the machinations that people engage in…

We definitely learn common sense — One of my newly found and favourite authors on logic, Walid Saba, just posted an article with the title “Why Commonsense Knowledge is not (and can not be) Learned”. Woh! Now there is a challenge for you. Take it if you dare. I do. My research revolves around all of…

Exploring the future of graph databases and knowledge graphs — If the term Relational Knowledge Graph is not on your radar, I suspect it soon will be. Bob Muglia, former CEO of Snowflake is now a board director of a startup that is promoting the new paradigm. My earlier thinking of nomenclature gravitated towards introduction of the term graphational databases…

Part of The Future of Graph Databases Series — Pt. 2 — In a previous article in this series I outlined where the Boston conceptual modelling software represents edge types in property graph schema (PGS) that represent many-to-many relationships as a link with a double arrow. The image above shows edge types (e.g. Session is at Cinema) as a dashed line. …

Part of The Future of Graph Databases Series — Pt. 1 — My business, FactEngine, makes a software tool for the development of Property Graph Schema (PGS) for the design of graph databases, and I have a vested interest in the future of graph databases. One of the biggest problems with current trends in Property Graph Schema development is the lack of…

Open Database Connectivity and “Relational always wins” — In a recent interview, Molham Aref of Relational.AI claimed that “Relational always wins”, intimating that of all the database paradigms that of the relational database always wins. When I think about these things I tend to agree with Molham, but for reasons not discussed in the interview…that reason being a…
