Software Wasteland
by Dave McComb | Business Case & ROI
Software Wasteland: Know what’s causing application development waste so you can turn the tide. Software Wasteland is the book your Systems Integrator and your Application Software vendor don’t want you to read. Enterprise IT (Information Technology) is a $3.8 trillion […]
Ontology-based Applications
by Dave McComb | Knowledge Graphs & Ontologies
Once you have your ontology, you want to put it to use. We will describe a common scenario where data is extracted from various sources including relational databases. That data is then used in conjunction with an application instead of […]
Data-Centric’s Role in the Reduction of Complexity
by Dave McComb | Data-Centric Architecture
Complexity Drives Cost in Information Systems A system with twice the number of lines of code will typically cost more than twice as much to build and maintain. There is no economy of scale in enterprise applications. There is diseconomy […]
The Core Model at the Heart of Your Architecture
by Dave McComb | Data-Centric Architecture
We have taken the position that a core model is an essential part of your data-centric architecture. In this article, we will review what a core model is, how to go about building one, and how to apply it both […]
Enterprise Ontology, Semantic Silos, and Cowpaths
by Michael Uschold | Knowledge Graphs & Ontologies
Paving Cow Paths Numerous modern day streets in downtown Boston defy logic—until you realize that the city fathers literally paved over the transit system created and used by cows.* This gave the immediate benefit of getting places faster, while losing […]
A Semantic Bank
by Dave McComb | Financial Services
In brief: A semantic bank, as this post defines it, is a bank whose information systems run through a single conceptual model that is directly implemented: a query to the model returns production data, and a transaction stated in the […]
The Data-Centric Revolution: Integration Debt
by Dave McComb | Business Case & ROI
Integration Debt is a Form of Technical Debt As with so many things, we owe the coining of the metaphor “Technical Debt” to Ward Cunningham and the agile community. It is the confluence of several interesting conclusions the community has […]
The Inelegance of having Brothers and Sisters
by Michael Uschold | Knowledge Graphs & Ontologies
This blog follows from a recent blog by Dan Carey called Screwdrivers and Properties. It points to a longer whitepaper on the topic of avoiding property proliferation. One way we keep the number of primitives small is to avoid creating […]
Whitepaper: Avoiding Property Proliferation
by Dan Carey | Knowledge Graphs & Ontologies
Domain and range for ontological properties are not about data integrity, but logical necessity. Misusing them leads to an inelegant (and unnecessary) proliferation of properties. Logical Necessity Meets Elegance Screwdrivers generally have only a small set of head configurations (flat, […]
Screwdrivers & Properties
by Dan Carey | Knowledge Graphs & Ontologies
Screwdrivers generally have only a small set of head configurations (flat, Phillips, hex) because the intention is to make accessing contents or securing parts easy (or at least uniform). Now imagine how frustrating it would be if every screw and […]
Binary Instances
by Michael Uschold | Knowledge Graphs & Ontologies
Sometimes when we’re designing ontologies we’re faced with design choices that would lead us to create what we call “binary instances” or a situation where it will take the instantiation of two instances (often of different classes) in order to […]
Greatest hits from the Data-Centric Manifesto
by Dave McComb | Data-Centric Architecture
I was just reading through what some folks have written on the Data-Centric Manifesto web site. Thought I’d capture some of the more poignant: “I believe [Linked] Data Centric approach is the way of the future. I am committing my company […]
