When building predictive models the data scientist can spend a large amount of time examining the models produced and how they work and perform on their hold out sample data sets. They do this to understand is the model gives a good general representation of the data and can identify/predict many different scenarios. When the "best" model has been selected then this is typically deployed is some sort of reporting environment, where a list is (more...)
Sometimes love isn’t fair
A teenager, just emerging from an awkward growing phase drives a tendency to spew non sensical permutations of varying cringe worthy affections toward their love target. The data points behind the intent are solid. Let’s go Boolean now:
Intent of good = 1 ;
attracted to target = 1;
ability to provide for target = 1;
time available = 1;
prior or current committed relationship = 0.
So here (more...)
OBIEE 12c has changed quite a lot in how it manages configuration. In OBIEE 11g configuration was based around system MBeans and the
biee-domain.xml as the master copy of settings – and if you updated a configuration directly that was centrally managed, it would get reverted back. Now in OBIEE 12c configuration can be managed directly in text files again – but also through EM still (not to mention WLST). Confused? Yep, I (more...)
It’s Sunday night (well, technically Monday morning now), and we have just enough time for another one of my Data Integration Tips. This one, revolving around Oracle Data Integrator 12c, has been on my mind for some time now, so I figured we better just get it out there. Imagine this; you’ve upgraded from Oracle Data Integrator (ODI) 11g to ODI 12c and executed the first test Mapping. But hey…what happened to my C$ table (more...)
Oracle Data Visualisation Desktop has the feature of being able to include some advanced analytics. In a previous blog post I showed you how to go about installing Oracle R Distribution on your desktop/client machine. This will allow you to make use of some of the advanced analytics features of Oracle Data Visualization Desktop.
The best way to get started with using the advanced analytics features of Oracle Data Visualization Desktop, is to ignore that (more...)
Oracle Data Visualization comes with all the typical features you have with Visual Analyzer that is part of BICS, DVCS and OBIEE.
An additional install you may want to do is to install the R language for Oracle Data Visualization Desktop. This is required to enable the Advanced Analytics feature of the tool.
After installing Data Visualisation Desktop when you open the Advanced Analytics section and try to add one of the Advanced Analytics graphing (more...)
A recent addition to the Oracle lineup of visualization tools is the Oracle Data Visualization Desktop. Described by Oracle as a “single user desktop application that provides Oracle Data Visualization functionality to business users,” ODVD is an easy-to-install data visualization tool for Windows 7, 8 or 10 that packs some very powerful features.
I recently had a chance to sit down and explore ODVD and wanted to share some of my first impressions.
At its (more...)
Using Oracle Data Visualisation is just the same or very similar as to using the Cloud version of the tool.
In this blog post I will walk you through the steps you need to perform the first time you use the Oracle Data Visualization client tool and to quickly create some visualizations.
Step 1 - Create a Connection to your Oracle DB and Schema
After opening Oracle Data Visualisation client tool client on the Data (more...)
After a bit of a long wait Oracle have finally release Oracle Data Visualization for the desktop. The desktop version of this tool is only available for Windows desktops at the moment. I'm sure Oracle will be bringing out versions of other OS soon (I hope).
To get you hands on the Oracle Data Visualization to to the following OTN webpage (click on this image)
After downloading has finished, you can run the installer.
When you install R you also get a set of pre-compiled datasets. These are great for trying out many of the features that are available with R and all the new packages that are being produced on an almost daily basis.
The exact list of data sets available will depend on the version of R that you are using.
To get the list of available data sets in R you can run the following.
Elastic announced their Graph tool at ElastiCON 2016 (see presentation here). It’s part of the forthcoming X-Pack which bundles Graph along with other helper tools such as Shield and Marvel. Graph itself is two things; an extension of Elasticsearch’s capabilities, enabling the user to explore how items indexed in Elasticsearch are related, and a plugin for Kibana that acts as an optional front-end for this new functionality.
You can find a good (more...)
Where You Are Now
OBIEE 12c has been out for some time, and it seems like most folks are delaying upgrading to OBIEE 12c until the very last minute. Or at least until Oracle decides to put out another major version change of OBIEE, which is understandable. You’ve already spent time and money and devoted hundreds of resource hours to system monitoring, maintenance, testing, and development. Maybe you’ve invested in staff training to try to maximize (more...)

Hey everyone, it’s Sunday night and we have just enough time for another Data Integration Tip from Rittman Mead. This one has originated from many years of Oracle Data Integrator experience – and several lost passwords. Let me start first by stating there is never any blame placed when a password is lost, forgotten, or just never stored away in a safe place. It happens more often than you might wish to think! Unfortunately, there is (more...)
Like me, if you are a big user of Discoverer, you would have been alarmed at the news a few years ago that Oracle was dropping the tool.
Well, once I got over my alarm I started to think about how my clients could maximize their use of the at times millions of dollars of investment.
Oracle Corporation’s statement of direction implies that they will not force you off of Discoverer and (more...)

You have heard about the cloud? Right? Even the Oracle Cloud?
If you haven't, then maybe we need to look at how you can learn more about the Oracle Cloud.
Over the past while, and in the past few weeks in particular, Oracle has been advertising about how you can get a trail Oracle cloud service setup for FREE. Well it is free for one month when you set it up on the Oracle website (more...)
It’s that time of year again when Oracle technologists from around the world gather in Las Vegas, NV to teach, learn, and, of course, network with their peers. The Collaborate conference, running for 10 years now, has been a collaboration, if you will, between the Independent Oracle Users Group (IOUG), Oracle Applications Users Group (OAUG) and Quest International Users Group (Quest), making it one of the largest user group conferences in the world. Rittman (more...)
A user’s workflow shouldn’t change to accommodate a new tool. A new tool should fill a gap in the current workflow and help streamline the user’s process. An application without a clearly defined scope eventually overlaps with existing solutions, creating confusion and distress among users. It takes both time and effort to clarify the appropriate situations to use the application, reconcile different use cases and approaches, and resolve incorrect uses. We designed ChitChat with appropriate (more...)
I’m pleased to have recently had my first article published on the Oracle Technology Network (OTN). You can read it in its full splendour and glory (!) over there, but I thought I’d give a bit of background to it here and the tools demonstrated within.

One of the things that we frequently help our clients with is reviewing and optimising the performance of their OBIEE systems. As part (more...)
