Introducing Oracle Big Data Discovery Part 3: Data Exploration and Visualization

In the first two posts in this series, we looked at what Oracle Big Data Discovery is and how you can use it to sample, cleanse and then catalog data in your Hadoop-based data reservoir. At the end of that second post we’d loaded some webserver log data into BDD, and then uploaded some additional reference data that we then joined to the log file dataset to provide descriptive attributes to add to the base (more...)

Introducing Oracle Big Data Discovery Part 2: Data Transformation, Wrangling and Exploration

In yesterday’s post I looked at Oracle Big Data Discovery and how it brought the search and analytic capabilities of Endeca to Hadoop. We looked at how the Oracle Endeca Information Discovery Studio application works with a version of the Endeca Server engine to analyse and visualise sample sets of data from the Hadoop cluster, and how it uses Apache Spark to retrieve data from Hadoop and then transform that data to make it more (more...)

Patching the Big Data Appliance

I have been patching engineered systems since the launch of the Exadata V2 and recently i had the opportunity to patch the BDA we have in house. As far as comparisons go, this is were the similarities stop between Exadata and a Big Data Appliance (BDA) patching.
Our BDA is a so called startes rack consisting of 6 nodes running a hadoop cluster, for more information about this read my First Impressions blog post. On (more...)

Oracle Business Analytics Update

Last week I visited the Oracle Business Analytics Partner Update at Oracle NL in Utrecht, the Netherlands. The NL (Pre-) Sales gave us an update of the Oracle Analytics Roadmap. There is a lot of movement in the world of Oracle Analytics. I have written about the publications during Oracle Open World 2014. When we look back…Read more Oracle Business Analytics Update

Waarin ik laat zien dat juist architectuur waarde en snelheid kan bieden bij de time-to-market. Dit aan de (more...)

Big Data and the importance of Meta-Data

Data isn't really respected in businesses, you can see that because unlike other corporate assets there is rarely a decent corporate catalog that shows what exists and who has it.  In the vast majority of companies there is more effort and automation put into tracking laptops than there is into cataloging and curating information. Historically we've sort of been able to get away with this

Security Big Data – Part 7 – a summary

Over six parts I've gone through a bit of a journey on what Big Data Security is all about. Securing Big Data is about layers Use the power of Big Data to secure Big Data How maths and machine learning helps Why its how you alert that matters Why Information Security is part of Information Governance Classifying Risk and the importance of Meta-Data The fundamental point here is that

Securing Big Data Part 6 – Classifying risk

So now your Information Governance groups consider Information Security to be important you have to then think about how they should be classifying the risk.  Now there are docs out there on some of these which talk about frameworks.  British Columbia's government has one for instance that talks about High, Medium and Low risk, but for me that really misses the point and over simplifies the

Securing Big Data Part 5 – your Big Data Security team

What does your security team look like today? Or the IT equivalent, "the folks that say no".  The point is that in most companies information security isn't actually something that is considered important.  How do I know this?  Well because basically most IT Security teams are the equivalent of the nightclub bouncers, they aren't the people who own the club, they aren't as important as the

Securing Big Data – Part 4 – Not crying Wolf.

In the first three parts of this I talked about how Securing Big Data is about layers, and then about how you need to use the power of Big Data to secure Big Data, then how maths and machine learning helps to identify what is reasonable and was is anomalous. The Target Credit Card hack highlights this problem.  Alerts were made, lights did flash.  The problem was that so many lights flashed and

Securing Big Data – Part 3 – Security through Maths

In the first two parts of this I talked about how Securing Big Data is about layers, and then about how you need to use the power of Big Data to secure Big Data.  The next part is "what do you do with all that data?".   This is where Machine Learning and Mathematics comes in, in other words its about how you use Big Data analytics to secure Big Data. What you want (more...)

Are you ready to learn something new in 2015?

We all know the saying: When the student is ready, the teacher will appear My advice is to empty your cup, daily, so that when the teacher appears you will recognize them. Unless we are humble in our hearts and in our spirit, we are not open to new things and to learning. The teacher […]

Securing Big Data – Part 2 – understanding the data required to secure it

In the first part of Securing Big Data I talked about the two different types of security.  The traditional IT and ACL security that needs to be done to match traditional solutions with an RDBMS but that is pretty much where those systems stop in terms of security which means they don't address the real threats out there, which are to do with cyber attacks and social engineering.  An ACL is only

Securing Big Data – Part 1

As Big Data and its technologies such as Hadoop head deeper into the enterprise so questions around compliance and security rear their heads. The first interesting point in this is that it shows the approach to security that many of the Silicon Valley companies that use Hadoop at scale have taken, namely pretty little really.  It isn't that protecting information has been seen as a massively

Watch: Riak vs. Oracle

Every data platform has its value, and deciding which one will work best for your big data objectives can be tricky—Alex Gorbachev, Oracle ACE Director, Cloudera Champion of Big Data, and Chief Technology Officer at Pythian, has recorded a series of videos comparing the various big data platforms and presents use cases to help you identify which ones will best suit your needs.

Riak and Oracle are completely different platforms. Alex explains that “Oracle database (more...)

What makes MapR superior to other Hadoop distributions?

These days Hortonworks with their IPO and Cloudera sitting on $1bn of cash grab all the headlines. However,the real visionary in the field is someone else. Someone blasting the previous world record in TeraSort . A Hadoop distribution on both Amazon Web Services and the Google Compute Engine. A company that Google is invested in. While their competitors have been in skirmishes with each other, MapR has been quietly working away and innovating.
