We (Gorcan, Glen, Debra and I) arrived into Mexico around 10pm and had a few minutes wait for our local user group contact to meet us. They had arranged transportation to our hotel.
The next morning (Friday) was the day of the OUG Mexico conference. We were collected from the hotel and taken to the conference venue. Our transport had to made a number of trips to/from the conference venue to cater for all the (more...)
There are various tell-tale signs that something is not quite right with your Oracle Data Integrator implementation. Does your ODI architecture suffer from the following symptoms?
- The ETL seems to take forever
- Some data flows take more than 30 minutes
- Your developers take ages to implement new data flows or change existing mappings
- The ETL breaks at least once a week
- No meaningful and consistent set of naming standards and coding conventions has been implemented.
After the OUG Panama conference we arrived later that night in San Jose the capitol of Costa Rica. The whole emigration, luggage pick up and customs was the smoothest experiences I have ever experienced at an airport. All was done in a matter of minutes. All the booths for emigration and customs was open and staffed. When was the last time you have ever seen this before. It was a very positive start to our (more...)
The OTN Tour of Latin America has come to an end and I was very lucky to have been a part of Northern part of the tour.
My OTN Tour consisted of visiting 3 countries in one week and giving 8 hours of presentations. This blog post looks back at the OUG Panama conference and I'll have separate blog posts for each of the other countries.
My travels stared the Saturday before the OUG Panama (more...)
I will give a presentation on 24 September at the Jury’s Inn in Dublin on the next generation of Big Data 2.0 tools and architecture.
Over the last two years there have been significant changes and improvements in the various Big Data frameworks. With the release of Yarn (Hadoop 2.0) the most popular of these platforms now allows you to run mixed workloads. Gone are the days when Hadoop was only good for (more...)
There’s a good chance that, if you’re reading this, you likely perform some reporting, analytics, data stewardship role or probably some combination of all three. And be it for a large corporation or a small company, there are likely standards and practices that pertain to how the above jobs are performed on a day to day basis; not easily changed and perpetually validated by big budgets and long careers. It is equally likely that (more...)
One of the main things I get asked to do here at Rittman Mead, is deliver the OBIEE front-end training course (TRN 202). This a great course that has served both us, and our clients well over the years. It has always been in high demand and always delivered with great feedback from those in attendance. However, as with all things in life and business, there is going to be room for improvement and opportunities (more...)
Over the past couple of years Rittman Mead have been broadening our skills and competencies out from core OBIEE, ODI and Oracle data warehousing into the new “emerging” analytic platforms: R and database advanced analytics, Hadoop, cloud and clustered/distributed systems. As we talked about in the recent series of updated Oracle Information Management Reference Architecture blog posts and my initial look at the Oracle Big Data SQL product, our customers are increasingly looking to (more...)

Some of you may be aware that I have been writing a on Oracle Data Miner. Actually the book covers the Oracle Data Miner GUI that is part of SQL Developer, the SQL and PL/SQL functions, procedures and packages that form the Oracle Data Mining option in the database and lots of other topics for the DBA, Developer and BI/DW people.
Today is a bit day for this book as it is officially released and (more...)
The headline articles of Oracle Magazine for November/December 2000 were on how application service providers are changing the way that business operate, everything from project management collaboration, professional services, online marking and how to go about becoming one.
Other articles included:
- Tom Kyte has an article on how working with Java is simpliernow that it is a native part of the Oracle database. He gives some examples of how to get some of the typical (more...)
In my previous blog post I gave some PL/SQL that performed the tokenising of a string. Check out this blog post here.
Thanks also to the people who sent me links examples of how to tokenise a string using the MODEL clause. Yes there are lots of examples of this out there on the interest.
While performing the various searches on the internet I did come across some examples of using Regular Expressions to extract (more...)
One tag. Rant.
Every now and then when I'm on the OTN forums, I run into gems like this: https://community.oracle.com/thread/3589607
The problem isn't the question - it's the "answer" which is both mind-blowingly wrong on so many levels and ends with the usual childish "Gimme points, I crave attention!" footer. I'm not going to go into details on the technical solution since that's covered in my response to the thread itself, but (more...)
Some time ago I had some blog posts introducing some of the basic Statistical function available in Oracle. Here are the links to these.
Both ODI and the Hadoop ecosystem share a common design philosophy. Bring the processing to the data rather than the other way around. Sounds logical, doesn’t it? Why move Terabytes of data around your network if you can process it all in the one place. Why invest millions in additional servers and hardware just to transform and process your data?
In the ODI world this approach is known as ELT. ELT is a marketing concept (more...)
