Many people come up to me in the street and ask me what Big Data is all about. It has happened to me so many times in the past that I am convinced that it might just happen to you as well. I know sort of thing, I read the Big Data tealeaves. Nothing gets past me.
The first time a complete stranger came up to me in public and said “Hello, will you tell me what this Big Data lark is all about then?” I was lost for words, you just ask my Aunt Dolly, he can vouch for that, no problem. Later that day I read a book – it was my dad’s book – and I then decided to adopt a strategy.
Therefore, in the spirit of springtime goodwill to all men and women, I have put together this blog piece in that hope that it will enlighten, help and entertain.
What is big data?
Big Data can be characterised by the 10 Vs – yes, 10, not 4. Which, in my book, is more than enough to bring up-to-speed the average Big Data John or Jane that one meets on the street, and who naturally wish to be informed of such matters.
In layperson’s terms this a series of landmarks and pointers in the analytics space used to frame and guide the didactic aspects of Big Data.
The fundamental Vs of the Big Data canon are these:
So, let me now explain what each of these characteristics mean to those who might know and for those who might want to know.
Vagueness: This is perhaps the trickiest of questions to address, given the vast panorama that is cast before this incredibly complex yet easily graspable concept. But let me state this, and let there be no mistake about it. At this point in time, what makes Big Data vague is also what makes Big Data specific, explicit and certain. That is to say, in order to ‘come to an understanding’ of Big Data, it is necessary to completely embrace the dialectic of knowing the unknowable. So belief is an absolute essential element – belief and data, that is.
Volume – If there ever was a time to “pump up the volume”, we have it here with Big Data.
Big, voluminous, gorgeously rotund and infinite. Big Data is called Big Data because there is a lovely, roly-poly, likeable never-ending load of it. Its volumes can be measured in zeta-bytes, which you can be assured, is a helluva lot of data.
Variety – As they might say down my way, “variety is the spice of life, innit”. This is what makes Big Data so special. So appealing.
Because before Big Data there was absolutely no variety in anything, at all. We lived in a bland world, bereft of detail, nuance and diversity. Nothing could be measured, analysed or explained, because we lacked Big Data. We were ignorant. So ignorant and stupid that we couldn’t see the sense of putting the diapers next to the beer, or of offering three for the price of two.
Fortunately, today this is no longer the case if we don’t want it to be, and thanks to Big Data we have a veritable sensorial explosion. No longer is IT just a couple of symbols scribbled in crayon on someone’s school notebook.
Virility – Move over Smart Data, the new kid on the block is Big Data.
If Big Data were described in the manner of a religious text, it would be accompanied by a never ending narrative of begets.
So, what does that mean?
Simply stated, Big Data creates itself, in and of itself. The more Big Data you have, the more Big Data gets created. It’s like a self-fulfilling prophecy in 360 degree, high-definition, poly-faceted and all-encompassing knowing. The sort of thing that governments would pay an arm and a leg to get their mitts on.
Velocity – Velocity is of the essence. Velocity kills the competition. More velocity, less haste.
We demand that service is ‘velocious’. ‘Everything’ must be ‘now’, or it’s too late.
This means we need to be able to handle Big Data at velocity – at the speed of need.
Charles Babbage once stated (or maybe it was more than once) that “whenever the work is itself light, it becomes necessary, in order to economize time, to increase the velocity.”
But remember, we are dealing with mega-velocity here, so don’t drink and drive the Big Data Steamship, Star-ship or Mustang.
Vendible – If you can sell it, and sell it as Big Data, then it ‘is’ Big Data. If you can’t, then it’s not. The saleability of Big Data proves its existence.
So, what are the vendible aspects of Big Data?
Let’s leave that easy question for another day. But for now I can confidently state that it is used to mobilise armies of commentators, industry analysts, publicists, punters, writers, bloggers, gurus, futurologists, conference organisers, conference speakers, educators, customer relationship managers, salespeople, marketers and admen.
Vaticination – Edmund Burke is down on record as stating that “you can never plan the future by the past”. Now Burke may have been a clever person when it came to many things, but he wasn’t exactly a whiz when it came to Big Data.
There are people in the world who are in no doubt that Big Data provides the sort of visionary and predictive powers only previously obtainable through ritual sacrifice, magic potions and the casting of spells. Others are highly critical of the understatement implicit in this belief.
For many, Big Data will make the Oracle of Delphi look like a mere call centre.
This is why the power of vaticination plays a characteristically important role in the world of Big Data.
Voracity – This is based on the quasi-rationalist argument that Big Data is big and it has an omnipresent and insatiable self-fulfilling desire.
Big Data comes with an attendant requirement for hardware, even if it is a whole load of consumer hardware tacked together in a magnificent and miraculous mesh of magic.
Big Data can be characterised by voracity, but this comes hand in hand with the ‘ventripotent’ IT industry.
Veracity – The eminence of the data being captured for Big Data handling can vary significantly. The quality or lack of quality of the data naturally has the potential to impact the accuracy of analysis using that data.
Before Big Data arrived on the scene we knew nothing about Data Quality or data verification. This is why ETL and Data Cleansing tools lacked the power to effectively quality check and verify data, to ensure that any erroneous or anomalous data was rejected or flagged.
But now, with the sophistication of tools such as ‘grep’ and ‘awk’ at our disposal, we have the power in our hands to ensure nothing ‘dodgy’ gets into the analytical mix.
Vanity – In my opinion, to fully grasp the underlying and profound meaning of Big Data, it is essential for us to understand the difference between vanity and conceit. Max Counsell claimed that “Vanity is the flatterer of the soul”. Goethe characterised vanity as being “a desire for personal glory”. After an incident with an Anarchist (presumably a Big Data Anarchist), Blackadder remarked to Baldrick that “The criminal’s vanity always makes them make one tiny but fatal mistake. Theirs was to have their entire conspiracy printed and published in plain manuscript”.
So that ends the brief rundown of the defining characteristics of Big Data.
So, to summarise. That, which has passed before, necessarily divulges both the upside and downside of Big Data. By reaching out, opening up the kimono and relating the 10 Vs we are disclosing that which cannot be disclosed, exhibiting the absence of essential essence, and thereby opening up the entire field, discipline, profession, science and art to examination, questioning and ridicule.
Many thanks for reading.

Dark data, what is it and why all the fuss?
First, I’ll give you the short answer. The right dark data, just like its brother right Big Data, can be monetised – honest, guv! There’s loadsa money to be made from dark data by ‘them that want to’, and as value propositions go, seriously, what could be more attractive?
Let’s take a look at the market.
Gartner defines dark data as “the information assets organizations collect, process and store during regular business activities, but generally fail to use for other purposes” (IT Glossary – Gartner)
Techopedia describes dark data as being data that is “found in log files and data archives stored within large enterprise class data storage locations. It includes all data objects and types that have yet to be analyzed for any business or competitive intelligence or aid in business decision making.” (Techopedia – Cory Jannsen)
Cory also wrote that “IDC, a research firm, stated that up to 90 percent of big data is dark data.”
In an interesting whitepaper from C2C Systems it was noted that “PST files and ZIP files account for nearly 90% of dark data by IDC Estimates.” and that dark data is “Very simply, all those bits and pieces of data floating around in your environment that aren’t fully accounted for:” (Dark Data, Dark Email – C2C Systems)
Elsewhere, Charles Fiori defined dark data as “data whose existence is either unknown to a firm, known but inaccessible, too costly to access or inaccessible because of compliance concerns.” (Shedding Light on Dark Data – Michael Shashoua)
Not quite the last insight, but in a piece published by Datameer, John Nicholson wrote that “Research firm IDC estimates that 90 percent of digital data is dark.” And went on to state that “This dark data may come in the form of machine or sensor logs” (Shine Light on Dark Data – Joe Nicholson via Datameer)
Finally, Lug Bergman of NGDATA wrote this in a sponsored piece in Wired: “It” – dark data – “is different for each organization, but it is essentially data that is not being used to get a 360 degree view of a customer.
Okay, let’s see if we can be a bit more specific about the content of dark data?
Items on the dark data ticket include: Email; Instant messages; documents; Sharepoint content; content of collaboration databases; ZIP files; log files; archived sensor and signal data; archived web content; aged audit trails; operational database backups – full and incremental; roll-back, redo and spooled data files; sunsetted applications (code and documentation); partially developed and then abandoned applications; and, code snippets.
Most importantly, dark data is data that is not actively in use, is underutilised, or is something else. Seriously.
So, the conclusion that some have come to is this: there is a vast collection of data in various formats waiting to be monetised.
Personally, the idea that really grabs my attention is the potential ability to do novel forensic research on email. If only to find out what happened in the past.
For example, maybe it would be fascinating to see how significant challenges were identified, flagged and discussed; how strategic responses to those challenges were formulated, chosen and executed; and, how the outcomes of all of that process were reflected in email communications.
I think that this line of work can be very interesting for some people, and that interesting insights may be uncovered, but I would hate to have to put a tangible value on it, if only to avoid adding to the already galactic magnitudes of nonsense and hype surrounding certain data topics.
There are other more mundane uses of dark data.
Imagine that you are just about to embark on a Data Warehouse project (you really are a late adopter aren’t you), and you want establish a base collection of historical data. Where do you get that historical data from?
Right! Operational databases are not characteristically used to store significant amounts of historical reference data and historical transactions beyond a certain time window; there are performance and other reasons for keeping OLTP systems as lean as possible, so, initial loads of historical data is typically recreated in the Data Warehouse from backups, audit trails or logs.
You don’t need a Chief Data Officer in order to be able to catalogue all your data assets. However, it is still good idea to have a reliable inventory of all your business data, including the euphemistically termed Big Data and dark data.
If you have such an inventory, you will know:
What you have, where it is, where it came from, what it is used in, what qualitative or quantitative value it may have, and how it relates to other data (including metadata) and the business.
What needs to be kept, and for how long, and what can be safely discarded, and when.
The risks associated with the retention or loss of that data.
If you don’t have such a catalogue and have never done a data inventory then a full data inventory and audit seems to be your new best friend.
Simply stated, you may have dark data that has value, or it may be a simple collection of worthless digital nostalgia. But if you don’t know what you have, it may pay to find out what’s there, and if necessary, to let it go.
There is no point in hoarding unneeded and unwanted rubbish data. That is simply not good data management.
Finally a word on all the fuss surrounding dark data.
Failure to monetize when there is value to be obtained from dark data is one thing, claiming that value can be invariably obtained whilst actually not knowing what the data is, or how it could be monetised, is just adding to the mountain of data related ‘nonsense and hype’ doing the rounds these days. Please consider not adding to that mountain.
British Rail, the national UK rail Company, used to be notorious for the number of delays and cancellations to services, and their reasons for failing to meet their obligations became stranger and stranger.
In winter, it would snow and there would be problems. And people would ask ‘how come you couldn’t deal with the snow this year, we’ve had snow for centuries?’ And back came the answers ‘Yes, Sir, but this year it was the wrong type of snow’. In autumn (the fall), it was ‘the wrong types of leaves, and ‘the wrong type of rain’, and in Summer, the ‘wrong type of sunshine’ and so on and so forth.
I hope this will not be the excuse from the Big Data and dark data pundits and punters when the much-vaunted and ‘almost’ guaranteed monetisation isn’t frequently realised.
‘Of course Big Data gives you big dollar benefits, it was just littered with the wrong type of data’ or ‘you just weren’t trying hard enough’.
Many thanks for reading.
