Rittman Mead and Oracle Big Data Webcast Series – November 2015

We’re running a set of three webcasts together with Oracle on three popular use-cases for big data within an Oracle context – with the first one running tomorrow, November 3rd 2015 15:00 – 16:00 GMT / 16:00 – 17:00 CET on extending the data warehouse using Hadoop and NoSQL technologies.

The sessions are running over three weeks this month and look at ways we’re seeing Rittman Mead use big data technologies to extend the and capabilities of their (more...)

Oracle OpenWorld 2015 Roundup Part 2 : Data Integration, and Big Data (in the Cloud…)

In yesterdays part one of our three-part Oracle Openworld 2015 round-up, we looked at the launch of OBIEE12c just before Openworld itself, and the new Data Visualisation Cloud Service that Thomas Kurian demo’d in his mid-week keynote. In part two we’ll look at what happened around data integration both on-premise and in the cloud, along with big data – and as you’ll see they’re too topics that are very much linked this year.

First (more...)

Forays into Kafka 02 – Enabling Flexible Data Pipelines

One of the defining features of “Big Data” from a technologist’s point of view is the sheer number of tools and permutations at one’s disposal. Do you go Flume or Logstash? Avro or Thrift? Pig or Spark? Foo or Bar? (I made that last one up). This wealth of choice is wonderful because it means we can choose the right tool for the right job each time.

Of course, we need to establish that have (more...)

NoSQL quick 101 with Oracle NoSQL v3.4

Since I wrote my whitebook about Oracle NoSQL, some things have changed. Also I found out some things were not quite clear.  One of those confusing things, is that in the examples I call my host “weblogic” (the host I used in my demo), but when kvstore runs locally, it can be replaced by “localhost” .

I went through the examples with NoSQL 3.4 and Oracle JDK 1.8, en that resulted in the following steps for a (more...)

How many startups did Google purchase and what did it do with them?

Ever wondered, how may startups or companies did Google acquire so far and how much did it pay for them?

But the main question is, what happened to the acquired companies? Was it all waste of money?

With the recent re-structuring, Google became a subsidiary of Alphabet Inc., which now owns most of the parts.

Using infocaptor kpi dashboard software, we analyze the list of companies, products and services that Google has acquired (more...)

We are hiring!

Gluent – where I’m a cofounder & CEO – is hiring awesome developers and (big data) infrastructure specialists in US and UK!

We are still in stealth mode, so won’t be detailing publicly what exactly we are doing ;-)

However, it is evident that the modern data platforms (for example Hadoop) with their scalability, affordability-at-scale and freedom to use many different processing engines on open data formats are turning enterprise IT upside down.

This shift has already been going (more...)

Big Data for CIOs Presentation

A few months ago I was asked to give a two hours lecture to a group of CIOs. The topic was a bit vague – “Introduction to Big Data and NoSQL” but I agreed to give it a try anyway.

Since I feel Big Data is such a big topic and since I really wanted to give the CIO so added value, I created this presentation. The aim of the presentation wasn’t to cover all (more...)

The Basis Peak: Take a #selfie, see how exercise changes you

You’ve been running! Take a selfie, see how exercise changes you!” I smile when that message it pops into the notifications list on my Android smartphone when using the Basis Peak. All part of what endears me to using it even more to track my activity and sleep patterns.


The “smile-o-meter” approach of the Basis Peak Photo Finish feature is a great mix of the analog and digital, leveraging well-familiar smart phone functionality to (more...)

Oracle Architect’s Guides to Big Data

Over the past couple of years we have had a lot of information about Big Data presented to us. But one of the things that still stands out is that there is still a bit of confusion on what Big Data is. Depending on who you are talking to you will get a different definition and interpretation of what Big Data is and what you can do with it.

For example there is one company (more...)

Query existing HBase tables with SQL using Apache Phoenix

Spending a bit more time with Apache Phoenix in my previous post I realised that you can use it to query existing HBase tables. That is NOT tables created using Apache Phoenix, but HBase - the columnar NoSQL database in Hadoop.

I think this is cool as it gives you the ability to use SQL on an HBase table.

To test this, let's say you login to HBase and you create an HBase table like (more...)

Apache Phoenix, SQL is getting closer to Big Data

Here is a post about another project in the Big Data world, like Apache Hive from my previous post, enables you to do SQL on Big Data. It is called Apache Phoenix.

Phoenix is a bit different, a bit closer to my heart too, as I read the documentation on Apache Phoenix, the word 'algebra' and 'relational algebra' came across few times, and that mean only one thing, SQL! The use of (more...)

The Hybrid World is Coming

Here’s the video of E4 keynote we delivered together with Kerry Osborne a few weeks ago.

It explains what we see is coming, at a high level, from long time Oracle database professionals’ viewpoint and using database terminology (as the E4 audience is all Oracle users like us).

However, this change is not really about Oracle database world, it’s about a much wider shift in enterprise computing: modern Hadoop data lakes and clouds are here to stay. They are already taking over many workloads traditionally executed on (more...)

Hive (HiveQL) SQL for Hadoop Big Data

In this  post I will share my experience with an Apache Hadoop component called Hive which enables you to do SQL on an Apache Hadoop Big Data cluster.

Being a great fun of SQL and relational databases, this was my opportunity to set up a mechanism where I could transfer some (a lot)  data from a relational database into Hadoop and query it with SQL. Not a very difficult thing to do these days, actually (more...)

Handouts – Introducing Oracle’s Information Management Reference Architecture

One of the great things of working in the Oracle Business Analytics industry is the fact that there is a very active community. Both online as well as offline. Oracle supports these activities where possible. Last week I attended an offline session at Oracle HQ in the Netherlands. This session was a event organized by…Read more Handouts – Introducing Oracle’s Information Management Reference Architecture

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...)
