And then there was PAT.
PAT stands for Portable Appliance Testing
Yeah, as I’ve read, it’s pretty common here in Britain. I have to confess though, that it is a bit annoying. As I was living into University’s halls, I had to open the door to the PAT guys to test my appliance.
I will also cite this from the previous Wikipedia article, because I can.
“Misleading advice and advertising, often by companies who offer the testing, is contributing to low-risk businesses such as offices, shops and hotels paying unnecessarily for over-the-top maintenance regimes.
The law simply requires an employer to ensure that electrical equipment is maintained in order to prevent danger – it does not state that every item has to be tested or how often testing needs to be carried out.”

I am attending a Data Mining class here in London and hopefully I am quite interested in the field and I like it a lot.
Since I started my own research on the topic too, and I have tons of commercial data in the databases I administer for playing around, I found a very nice, free and open source tool (Can it get any better?) for the job, WEKA.
(Waikato Environment for Knowledge Analysis)
It is developed at the University of Waikato, New Zealand. Weka is free software available under the GNU General Public License.
One of the nice things of the software is that it uses JDBC (Java Database Connectivity), so you can connect to any database that supplies you with a JDBC driver. Also there is a JDBC to ODBC bridge driver, in order to connect to ODBC supported databases. So to sum things up, you can connect to almost every decent database management system.
Anyway, in theory it works really well, but there is a grey zone on how to practically connect to a database when using WEKA.

I have been using Oracle DB as a client, sending basic queries and doing basic DB work with the Oracle Application Express Web Interface.
This week, I installed and configured Oracle Enterprise Edition 12g on a Windows 2008 server cloud machine as well as Oracle Application Express 10g locally on my laptop.
