Multidimensional Thinking–24 Hours of Pass: Celebrating Women in Technology

smisner — Tue, 15 Mar 2011 23:04:53 GMT

It’s Day 1 of #24HOP and it’s been great to participate in this event with so many women from all over the world in one long training-fest. The SQL community has been abuzz on Twitter with running commentary which is fun to watch while listening to the current speaker. If you missed the fun today because you’re busy with all that work you’ve got to do – don’t despair. All sessions are recorded and will be available soon. Keep an eye on the 24 Hours of Pass page for details.

And the fun’s not over today. Rather than run 24 hours consecutively, #24HOP is now broken down into 12-hours over two days, so check out the schedule to see if there’s a session that interests you and fits your schedule. I’m pleased to announce that my business colleague Erika Bakse ( Blog | Twitter) will be presenting on Day 2 – her debut presentation for a PASS event. (And I’m also pleased to say she’s my daughter!)

Multidimensional Thinking: The Presentation

My contribution to this lineup of terrific speakers was Multidimensional Thinking. Here’s the abstract:

“Whether you’re developing Analysis Services cubes or creating PowerPivot workbooks, you need to get into a multidimensional frame of mind to produce a model that best enables users to answer their business questions on their own. Many database professionals struggle initially with multidimensional models because the data modeling process is much different than the one they use to produce traditional, third normal form databases. In this session, I’ll introduce you to the terminology of multidimensional modeling and step through the process of translating business requirements into a viable model.”

Kimball All the Way

There’s only so much I can cover in the time allotted, but I hope that I succeeded in my attempt to build a foundation that prepares you for starting out in business intelligence. One of my favorite resources that will get into much more detail about all kinds of scenarios (well beyond the basics!) is The Data Warehouse Toolkit (Second Edition) by Ralph Kimball. Anything from Kimball or the Kimball Group is worth reading.

Kimball material might take reading and re-reading a few times before it makes sense. From my own experience, I found that I actually had to just build my first data warehouse using dimensional modeling on faith that I was going the right direction because it just didn’t click with me initially. I’ve had years of practice since then and I can say it does get easier with practice. The most important thing, in my opinion, is that you simply must prototype a lot and solicit user feedback, because ultimately the model needs to make sense to them. They will definitely make sure you get it right!

Schema Generation

One question came up after the presentation about whether we use SQL Server Management Studio or Business Intelligence Development Studio (BIDS) to build the tables for the dimensional model. My answer? It really doesn’t matter how you create the tables. Use whatever method that you’re comfortable with. But just so happens that it IS possible to set up your design in BIDS as part of an Analysis Services project and to have BIDS generate the relational schema for you. I did a Webcast last year called Building a Data Mart with Integration Services that demonstrated how to do this. Yes, the subject was Integration Services, but as part of that presentation, I showed how to leverage Analysis Services to build the tables, and then I showed how to use Integration Services to load those tables. I blogged about this presentation in September 2010 and included downloads of the project that I used. In the blog post, I explained that I missed a step in the demonstration. Oops.

Just as an FYI, there were two more Webcasts to finish the story begun with the data – Accelerating Answers with Analysis Services and Delivering Information with Reporting Services.

If you want to just cut to the chase and learn how to use Analysis Services to build the tables, you can see the Using the Schema Generation Wizard topic in Books Online.

PASS Summit 2010: Epilogue

smisner — Mon, 15 Nov 2010 21:16:00 GMT

Another PASS Summit has come and gone, and a good time was had by all. The song at the opening keynote sums up the experience quite nicely, "Simply the Best." My favorite quote of the week comes from Andy Leonard (blog| twitter) who tweeted on November 9, "#sqlpass is a family reunion. :{>" Oddly enough, Andy is one of the few people that I DIDN'T get to see last week, but not for lack of trying. Sorry, Andy!

As an independent consultant, I don't get to interact regularly with my peers, so I love the reunion aspect of PASS. And now that I've started following people on Twitter, my universe of colleagues has expanded even more, and I was delighted to meet the people behind the avatars.

The joy of PASS is not limited to those of us who have attended for many years. As I was sitting in the airport last Friday, I recognized an attendee who was a first-timer and asked about his experience. He replied that it exceeded expectations. He was so anxious to get back to work to put what he learned into practice. He felt that the value of the knowledge that he is bringing back to the office from PASS was so much greater than the price of the conference. Now that's a ringing endorsement if I ever heard one.

There is so much more that could be said about PASS, and many in the community have already posted their thoughts on Twitter and on their blogs. There has been quite a stir in the business intelligence community this past week about the future of Analysis Services, about which I will comment in a future post. Today, however, I will focus on a few follow-up comments and links to resources related to activities in which I participated last week.

Getting Started In Blogging And Technical Speaking

Who had control of this very interactive session? You'll have to buy the PASS Summit DVD to find out!

I waited patiently for my turn to speak. With a room full of speakers, getting your own turn can be a challenge! I heard a few attendees express concern that they didn't know what to write about, or that someone else has covered the topic. My response to this concern is that everyone has a unique take on a topic, and that's why T-SQL Tuesday is such a great way both to learn and to contribute. T-SQL Tuesday was started by Adam Mechanic (blog | twitter) and gives everyone with an opinion (and who doesn't have one?) or a specific experience to add to the topic. You can see the first invitation to T-SQL Tuesday here to see how it all started and the most recent T-SQL Tuesday posts hosted by Paul Randal (blog | twitter). The best way to keep tabs on who's hosting the next round is to follow the #TSQL2sDay hash tag on Twitter.

Unfortunately, I didn't get to hang out for the entire presentation, because I had to move on to the…

Women in Technology Panel

I was honored to participate as a panelist for this year's Women in Technology luncheon. It was well attended, and I heard so many positive comments after the event from both men and women. I drew inspiration from my fellow panelists as well as the stories shared with me by other women attending PASS this year. You can view a recording of the event here if you're a registered member of PASS (which is free to join).

It's so difficult to say what the right answer is for increasing the numbers of women in technology. The numbers are diminishing at a deplorable rate (as I discussed in a previous post). It seems to me that to foster change we need to start laying the groundwork with our children. By "our children", I mean society in general, not me specifically, although I have tried do my part! On the one hand, I don't recommend forcing children into a career path that they can't embrace enthusiastically. On the other hand, I believe that one reason that girls don't pursue technology as an option is lack of exposure to the possibilities. Lynn Langit (blog | twitter) is a role model for showing kids (not just girls!) how to explore these possibilities through www.teachingkidsprogramming.org. Check it out!

Along these lines, I proposed that maybe - as great a community as PASS is - we should collectively think about what we can do for our kids. Someone tweeted that I suggested we should bring our daughters to SQLSaturday, but actually I wondered aloud if we could do something similar to SQLSaturday that focused on the kids (and not just girls). Maybe we could get some sponsors to help, too?

Demystifying MDX in Reporting Services

In this session, I explained some of the nuances of working with MDX in Reporting Services. I have posted my demo reports here.

In addition, you might want to refer back to some of my recent posts about using dynamic MDX in Reporting Services: Part 1 and Part 2.

If you're not familiar with MDX, I presented Session 07: Intro to MDX for 24 Hours of Pass: Summit Preview which you can view if you have a free PASS membership. MDX is not going away any time soon, contrary to recent rumors, so invest some time learning it if you plan to work with real Analysis Services cubes, which will continue to have their place in the BI stack for several years to come.

Real World Analysis Services Stored Procedures

This topic drew a larger audience than I expected as it's a fairly specialized topic. For years, I never needed to use Analysis Services Stored Procedures (ASSP), avoiding it because folklore said so due to performance hits. However, some things just can't be done any other way and I ran into such things this past year. To date, I haven't found much written about ASSP other than BOL, but you can find some excellent examples to download at CodePlex. Plus I've uploaded the very simple (non-production-ready) C# example that I used in my session demonstration for you to peruse.

What's Next?

So now that I've completed all the training and Webcasts and conference sessions that I've been focused on the last couple of months (with one exception - Delivering Information with Reporting Services, a free Webcast at 12 pm Pacific on Wednesday, November 17), I plan to get back to a more regular blogging schedule. There are certainly plenty of topics on my "to do" list!
