Have you ever wondered what the trend in movie releases has been for the past few decades? Comparing the number of Sci-Fi releases vs. Romantic Comedy releases? Me too, which is why I've taken my first look Oracle Data Visualization Desktop (DVD) to spot trends between these movie genres - Sci-Fi and the Romantic Comedy.
For this post, I found an interesting dataset from IMDB.com on Kaggle.com, listing a smattering of movies (more...)
We have a strong innovation spirit at Rittman Mead, with all staff encouraged to use technology to its best advantage in order to do things with the software that haven't been done before. Some of these projects may may be 'scratching the itch' of a repeated manual task that should be automated. Others use technology to extend the capabilities of the tools or write new ones to fill gaps that have been identified.
At Rittman (more...)
A few weeks ago the 12.2 Oracle Database was released on the cloud. I immediately set an account and got my 12.2 DBaaS setup. This was a relatively painless process and quick.
For me I wanted to test out all the new Oracle Advanced Analytics new features and the new features in SQL Developer 4.2 that only become visible when you are using the 12.2 Database.
When you are go to (more...)

Rittman Mead is happy to announce that its much anticipated On Demand Training (ODT) service is live, giving people the opportunity to receive expertly written & delivered self-paced training courses that can be accessed online anywhere, at anytime.
We have been delivering technical & end-user courses based on Oracle Analytics products all over the world for the past decade.
While our classroom sessions continue to offer an unrivalled experience for our trainees, we understand that (more...)
When working with the Clustering algorithms, and particularly k-Means, in the Oracle Data Miner tool there is no way of seeing how compact or dispersed the data is within a cluster.
There are a number of measures typically used in various tools and algorithms, but with Oracle Data Miner we are not presented with any of this information.
But if we flip from using the Oracle Data Miner tool to using SQL we can get (more...)
Rittman Mead has always had a long standing commitment to giving back, not only to the technology industry, but to local and global communities as well. Recently, Rittman Mead employees have been encouraged to take up to 40 paid hours to participate in community service opportunities. This year, I chose to use my 40 hours to serve at an orphanage in the Dong Nai province of Vietnam. The Bien Hoa Center for Supporting and Vocational (more...)
Yes you read the title of this blog post correctly!
Recently I was doing a bit a clear out and I came across a CD of the UKOUG Conference proceedings from 1999. That was my second UKOUG conference and how times have changed.
The CD contained all the conference proceedings consisting of slides and papers.
Here are some familiar names from back in 1999 who you may find presenting at this years conference, some you (more...)
Here is another email we got Wednesday from a Dodeca Excel Add-In for Essbase customer. This customer has a lot of VBA macros running some automation with Essbase and asked for some assistance. We told it was as easy as replacing they Essbase function declarations file with our Dodeca Add-In function declarations file, and then setting the variables that contain the location for the Dodeca-Essbase server. In other words, replace this file:

This year as always Rittman Mead is coming to UKOUG Tech 16 with a strong presence and a great line up of sessions covering OBIEE, ODI, Kafka, advanced visualisation and more. And yes, there will be Cloud!
Here is the details of the Rittman Mead sessions :
How many times have you been working on a project and something goes wrong, or the power shuts off, or you go on vacation and someone has messed with your code or somehow your work is lost? Well, now you have an alternative to safe proof your project work.
Versioning in ODI is allowed at various hierarchy levels within the instances and is stored in the master repository. What this means is that if you (more...)
One of the features everybody "loved" about OBIEE 11g were the Global Unique Identifiers (GUIDs), used to recognize users and groups based on an identifier that could be different from the username. The original aim of GUIDs was being able to distinguish different users sharing the same username coming from multiple Authentication Providers.
The GUIDs management could be tricky especially if they are not in sync between different environments, and could cause a wide range (more...)
I've recently performed several assessments to help our clients diagnose and fix their OBIEE performance problems. They often share similar design or implementation issues, and I thought it would be useful to present them here as a handy reference:
Mistake 1: No Software Monitoring
The key to happy users is to know there’s a problem (more...)
I’ve decided that it’s time for a refresher on Oracle Data Integrator 12c. This week in the “Oracle Data Integrator 12c: Getting Started” series: getting a quick start on mapping development. Several objects must be created before a single bit of ETL can even be created, and for those who are new to the product, as many readers of this series will be, that can be frustrating. The objects that must be in (more...)
If you are a user of the Oracle Data Miner tool (the workflow data mining tool that is part of SQL Developer), then you will have noticed that for many of the algorithms you can specify a Case Id attribute along with, say, the target attribute.
The idea is that you have one attribute that is a unique identifier for each case record. This may or may not be the case in your data model (more...)
Finally, I found something that I was looking for a long time, thought is would be very useful. A simplified maze of #MachineLearning #Algorithm feeling like Nirvana Today #MachinesWouldRuleWorld #AdvanceAnalytics
Hope this helps

“Superior Data Analytics is the antidote to Business Failure”
The Oracle 12.2c Database has been released and is currently available as a Cloud Service. The on-site version should be with us soon.
A few weeks ago I listed some of the new features that you will find in the Oracle Data Miner GUI tool (check out that blog post). I'll have another blog post soon that looks a bit closer at how the new OAA features are exposed in this tool.
I’ve decided that it’s time for a refresher on Oracle Data Integrator 12c. This week, I’m continuing the “Oracle Data Integrator 12c: Getting Started” series with the next topic: Installation and Configuration. I don’t plan to dig into all of the nitty gritty details on each specific scenario you might run into. Rittman Mead have an excellent training program for ODI 12c where you can ask the specifics. There is also this 100+ (more...)
