Azure for Enterprises: A June 2014 Video from Cloud Expo  
# Wednesday, July 09, 2014
I gave a general session on Azure for enterprises at the Cloud Expo conference in New York City last month. The target audience was IT leaders, and my goal was to describe why and how enterprises adopt public cloud platforms, using Microsoft Azure as a concrete example.

The video is interesting. The beginning looks like it's being recorded with a cellphone camera, complete with people's heads blocking the shot. But by the second minute or so, it settles into a nicely professional recording. Overall, it was a pleasure to be part of the event.

New Videos  
# Monday, June 30, 2014
Technology videos can be divisive: Some people love the format, others hate it.

If you're in the first group, I've posted a few new ones recently on various topics:

They're all short--mostly under ten minutes--and each one provides my perspective on a current IT topic.

# Friday, May 02, 2014
Business analytics, including data warehousing, BI, and data integration, is a rapidly evolving space. To help its SI partners in this area, Microsoft hired me to write a couple of guides:
The goal of both papers is to help Microsoft's SI partners for business analytics understand and make better decisions about their practices.

SQL Forever: Why Data Matters Most  
# Monday, April 28, 2014
I received a royalty check today for my first book, A Visual Introduction to SQL. The check wasn't very big, but the remarkable thing was that I received it at all.

I wrote this book with my friend Harvey Trimble in 1989, when SQL was a relatively new standard. A second edition was published a dozen years later, but it wasn't very different from the first--we added just a few things. Yet the book is still selling. (In fact, it's on an MIT syllabus for the Spring 2014 semester.) How many other 25-year-old technology books are still selling in more or less their original form?

I'm not making any claims about the book's quality here (although the Amazon  reviews are nice). What I'm impressed by is the longevity and the stability of SQL. Whatever NoSQL enthusiasts might wish, SQL is still a core technology in our industry, and it will be for a long time to come.

Why is this? One big reason is that the heart of IT isn't code--it's data. In fact, before the rise of the term "information technology", our field was called "data processing". Sometimes I wish that we still used that name, if only because it emphasized what was most important.

Yes, programming languages matter, and flashy interfaces on cool mobile devices are great, but none of these has much value without useful data to work on. And once data is stored in a particular form, such as relational tables, it's usually hard to change that form--hence the longevity of SQL.

Given all of this, I wouldn't be surprised to see our book still selling five or ten years from now. Maybe it's time to get to work on a third edition.

A Discussion about ALM and Modern Apps  
# Friday, March 07, 2014
I had a chance to talk with Richard Campbell and Carl Franklin for an episode of their ongoing Dot Net Rocks podcasts. They are incredibly smart guys, and so diverse. (If you haven't heard any of Carl's music, you really need to: Start here and here.)

We met after I'd just given a keynote (at the Computer History Museum, a very cool place) about the rise of devices and services apps and what this implies for application lifecycle management. Accordingly, this is what we talked about.

The podcast is here.

Barriers to the Public Cloud: A Short Interview  
# Sunday, March 02, 2014
David Giard, formerly a Sogeti consultant and now a technical evangelist at Microsoft, does an interesting video series called Technology and Friends. He interviewed me for this series a few weeks ago, where we talked mostly about the barriers to the public cloud.

It was a pleasure talking with David, and if you're interested, you can watch our conversation here.
