Oracle Open World is coming up in a few days time. This is a huge event that also incorporates Jave One and various other smaller conferences that are for specific product areas and for partners.
I will be presenting at Oracle Open World this year and I'll also be taking part in a number of other sessions/events including the Oracle ACE Directors briefing. Check out my blog post that list these sessions/events.
In addition to (more...)
Last time I wrote about the performance aspects of a BI system and how they could affect a user’s confidence. I concluded by mentioning that incorrect data might be generated by poorly coded ETL routines causing data loss or duplication. This time I am looking more at the quality of the data we load (or don’t load).
Back in the 1990’s I worked with a 4.5 TB DWH that had a single source for (more...)
I had an previous blog post listing the various Oracle Advanced Analytics sessions/presentation at Oracle Open World 2014.
After trawling through the list of Hands-on-Labs it was disappointing to see that there was no Oracle Data Mining or Oracle R Enterprise hands-on-labs this year.
But there is a hands on lab that looks are how to use the new SQL for Big Data feature (announced over the summer).
Here is the abstract for the session.
Looking back over some of my truly ancient Rittman Mead blogs (so old in fact that they came with me when I joined the company soon after Rittman Mead was launched), I see recurrent themes on why people “do” BI and what makes for successful implementations. After all, why would an organisation wish to invest serious money in a project if it does not give value either in terms of cost reduction or increasing profitability (more...)
With Oracle Open World just a few days away now, I was going through the list of presentations that are focused on using the Oracle Advanced Analytics Option. These will cover Oracle Data Miner and Oracle R Enterprise.
So I've decided to share this list with you :-) and hopefully I will get to see you are some or all of these sessions.
I am doing a repeat of my Kscope15 'Best Speaker' award-winning presentation as part of the ODTUG webcast series. Here is the official announcement from ODTUG:

Tim Tow, Applied OLAP
The Next Generation Outline Extractor is the follow-up to the classic OlapUnderground Essbase Outline Extractor used by thousands of Essbase customers. This session, which was the highest-rated (more...)
If you are attending Oracle Open World this year and fancy bit of a different experience, come and join Rittman Mead and Oracle’s Data Integration teams for drinks and networking at 7pm on Tuesday 30th September at the Local Edition speakeasy on Market Street.
We will be providing a couple of hours of free drinks with the opportunity to quiz our leading data integration experts and Oracle’s data integration team about any aspect of the (more...)
We have all been in the position of trying to find the name of a command in a language, particularly if you are not totally sure of the full command name.
I've been working with R a lot recently and in particular Oracle R Enterprise. I was always trying to remember what the full command name was. Then I found the apropos
function. The apropos function allows you to search R for commands based on (more...)
A few months ago I wrote a post on the blog around using Apache Flume to trickle-feed log data into HDFS and Hive, using the Rittman Mead website as the source for the log entries. Flume is a good technology to use for this type of capture requirement as it captures log entries, HTTP calls, JMS queue entries and other “event” sources easily, has a resilient architecture and integrates well with HDFS and Hive. (more...)
Virtualisation has revolutionised how we work as developers. A decade ago, using new software would mean trying to find room on a real tin server to install it, hoping it worked, and if it didn’t, picking apart the pieces probably leaving the server in a worse state than it was to begin with. Nowadays, we can just launch a virtual machine to give a clean environment and if it doesn’t work – trash it and (more...)
Over the weekend, Rittman Mead was listed in the Sunday Times Tech Track 100. We are extremely proud to get recognition for the business as well as our technical capability and expertise.
A lot of the public face of Rittman Mead focuses on the tools and technologies we work with. Since day one we have had a core policy to share as much information as possible. Even before the advent of social media, we shared (more...)

Last week I posted an article on the blog around analysing Twitter data using Datasift, MongoDB and Pig, where I used the Datasift service to stream tweets about Rittman Mead into a MongoDB NoSQL database, and then queried the dataset using Pig. The context for this is the idea of a “data reservoir”, where we supplement the more traditional file and relational datasets we find in data warehouses with other data, typically machine generated, (more...)
The next set of Ireland Oracle User Group SIG meetings will be on Wednesday 24th August. This will be a super SIG event with the following SIGs being run in parallel and all in one venue (Jurys Inn, Customs House, Dublin).
OUG Ireland BI & EPM SIG Meeting

Click on the links above for each SIG to get the details of agenda. There is a (more...)
If you followed our recent postings on the updated Oracle Information Management Reference Architecture, one of the key concepts we talk about is the “data reservoir”. This is a pool of additional data that you can add to your data warehouse, typically stored on Hadoop or NoSQL databases, where you store unstructured, semi-structured or unprocessed structured data in large volume and at low cost. Adding a data reservoir gives you the ability to leverage (more...)
This day 3 weeks time (on the 24th Sept) I will be heading out to San Francisco for Oracle Open World. Over the course on 9 days I will be taking part in the Oracle ACE Director briefing and in Oracle Open World. The following outlines my main activities, sessions that I'm presenting at and sessions that I have been asked to attend.
25th-26th Sept. I will be at the Oracle ACE Director briefing. This (more...)
The headline articles of Oracle Magazine for January/February 2001 were on how the current set of Oracle products supported the development and deployment of mobile and internet applications.
Other articles included:
- Oracle and HP form an alliance to develop and delivery CRM solutions aimed at helping companies keep up with customers in a world where rapid change is common place.
- In Tom Kyte's regular article he look at and gives examples of using function based (more...)
If you follow Blogs and Tweets from the Oracle community you won’t have missed hearing about the recent release of the first patch-set for Oracle 12c. With this release there are some significant pieces of new functionality that will be of interest to Data Warehouse DBAs and architects. The headline feature that most Oracle followers will know of is the new in-memory option. In my opinion this is a game-changer for how we design reporting (more...)
The In-Memory Option for Oracle Database 12c became available a few weeks ago with the 220.127.116.11 database patchset, adding column-store and in-memory capabilities to the Oracle Database. Unlike pure in-memory databases such as Oracle TimesTen, the in-memory option adds an in-memory column-store feature to the regular row-based storage in the Oracle database, creating in-memory copies of selected row-store tables in a compressed column-based storage format, with the whole process being automatic and (more...)
