Is Data Your Most Important Asset? #datalake, #nosql, #bigdata, #datavault

Published on 2014/06/30 by in Data Vault

In the coming posts I will be discussing data as an asset, and turning data in to information.  But in order to get there – we have to step back and first understand this notion of data lake, data swamp, NoSQL, Big Data, and Unstructured data.  We need to take a serious look at how all of these systems play together – or can they play together?  The problems with today’s data gathering is just that, we create data junkyards and data swamps by simply dumping more data into a common data store – without regard to it’s impact to business, IT, and the costs that it bears.

#datavault 2.0 Executive Meet & Greet in @CityOfSydney in August

Published on 2014/06/22 by in News

I am proud to say that the implementation of Data Vault 2.0 continues to gather momentum in Australia. I am visiting Sydney again in August to train and certify a large number of data modeling personnel within a Financial Services / Insurance company. I am seeing increasing interest in the application of Data Vault 2.0 principles within the realms of Agile/SCRUM, CMMI Level 5, big data, real-time, unstructured data, Hadoop, MPP databases and NoSQL.

#datavault standards, what really matters?

I’ve had the pleasure recently of discussing this topic both publicly and privately with all kinds of people in the Data Vault community.  For this, I say thank-you for all your wonderful insights.  I now see a bit where the confusion lies (ie: what is and is not a Data Vault), what are the acceptable modifications? can I make modifications and still call it a Data Vault?  how do I use and leverage the DV techniques without “being so rigid”, and yet make them work for my customers?

#datalake vs #datajunkyard for #bigdata and #datavault

Published on 2014/06/10 by in Data Vault

This post covers my opinion in what people today call a data lake.  I will discuss what I think needs to be done to clarify the terms, and why if left unmanaged, it quickly turns in to a data junkyard or polluted data lake.  On the flip side of the coin, today there is still valuein leveraging your existing relational database for your Data Vault data warehouse.

#datavault standards how & why

In recent times, there have been several discussions around the standards of the Data Vault Modeling components.  In fact, this isn’t the first time (nor the last) that I expect the standards to be challenged.  That said, I feel it necessary to discuss just what I put the standards through before publishing, in hopes that if you feel the urge to suggest changes, you can apply the same rigor as I do before telling the user group that “I’m wrong, the standards don’t work and here’s a change”.  This is a post in to the reasoning behind, the insight and the rigor applied to the standards (ALL standards) for the Data Vault 1.0 Model, and Data Vault 2.0 Model.

#teradata and #datavault 2.0 – thoughts on end dating

Published on 2014/05/20 by in Data Vault

Recently I taught a class on-site for a customer all about Data Vault 2.0.  When I got to the point where I shared the template / process for end-dating (updating end dates in place, using a characteristic function) I was point-blank told: “Teradata does not use or have indexes other than the Primary Index”  And that it would subsequently do a full table scan every time we wanted to execute a select from a satellite where the end date is NULL and has at least 2 or more “active” rows.
