PAT

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.

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.

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.
