August - Visualization 1 - SQL Execution Plan Volatility

The first visualization I will be working on is something I have been wanting for a while. I need a way to quickly show SQL Statement performance over time for 1 statement, especially to identify Execution Plan volatility. When researching performance problems I often need to quickly digest historical performance of a trouble statement - a statement that usually has run fine for years but now has started acting up.

5 in 5 - 5 Oracle visualizations in 5 months...

It is time for me to get my rear in gear. I have tons of notes floating around on Oracle administration and performance related visualizations I would like to work on but without a deadline things start dragging out... Like when you have a weight loss or stop smoking goal that becomes real when you tell people about it. Read more about 5 in 5 - 5 Oracle visualizations in 5 months...

Live Coding with JavaScript

I have been messing around in JavaScript and d3.js a bit more than usual lately.

In the past my JavaScript prototyping environment was a collection of html/js/json files on my local disk and a basic HTTP server (like python SimpleHTTPServer). I would edit files and reload reload reload reload. Very tiresome. Not very "2014" if you ask me.

Oracle Flashback Archive Licensing Info...

As the licensing of the Oracle Flashback Features has changed over recent releases I wanted to provide a summary. In 12c Oracle has opened up basic usage of Flashback Data Archive which is a handy way to add data archiving capabilities to existing/legacy applications.

A Delta to Plus/Delta... Good / Tricky / Different...

I have been encountering a lot of Plus/Delta activity at the end of my meetings and projects. Basically it is an informal feedback mechanism. A chance to communicate 1) what was good about the meeting and 2) what may need to be changed in the future.

One of my group leaders took it a step further though when applying it to tasks or projects. Read more about A Delta to Plus/Delta... Good / Tricky / Different...
