SQLBits XI in May 2013 – many reasons to attend! #sqlbits #dax #tabular

sqlbi — Wed, 20 Feb 2013 09:33:00 GMT

I and Alberto Ferrari will speak at SQLBits XI (Nottingham, UK – May 2-4, 2013) and there are many good reasons to join us there, especially if you are interested to DAX!

Here are our sessions:

Thursday, 02 May 2013 – Training Day - From 0 to DAX

The entire day is dedicated to learning DAX, starting from the syntax and going forward with more complex syntaxes for both expressions and queries in DAX.
Technical level: the goal is to be introductive, explaining the important concepts in DAX (such as filter context, row context, context transitions) and covering the usage of the most common DAX functions.
Target audience: Information Workers interested in exploiting the many interesting features of PowerPivot for Excel 2013 and BI developers who want to learn the DAX language.
In practice: if you started using DAX two years ago and created several projects in Tabular and/or PowerPivot with complex calculations, this is not the workshop for you (read about an Advanced DAX Workshop later in this post). But if you just started your first Tabular or PowerPivot projects and you are still wondering what CALCULATE is all about, then this is definitely the right training for you!

Friday, 03 May 2013 – 10:50am – Modern Data Warehousing Strategy

How to design a Data Warehouse in 2013? Should we change something considering the introduction of in-memory technologies such as xVelocity? Is Self-Service BI affecting the way we design and implement a Corporate Data Warehouse?
This is not a session about a specific feature of a product, but features and products have their effects on the data warehouse design. We’ll stop one hour trying to understand what changes in the big picture, affecting also our day-by-day job.

Friday, 03 May 2013 – 2:40pm – Inside xVelocity InMemory Engine (VertiPaq)

Do you use PowerPivot and/or Analysis Services Tabular? They use the same engine (xVelocity/VertiPaq) and you should know how it works.
This session will show how xVelocity/VertiPaq works, how it compresses and stores data and why it is so fast answering to your queries.
Why this is important? Because it is geeky! And because this knowledge will help you optimizing storage and DAX queries.

Saturday, 04 May 2013 – 10:50am – DAX Query Engine Internals

DAX is amazingly fast. But some query might be not fast enough.
Do you want to know how to optimize your DAX query? This session is for you.
Knowing the internals of xVelocity InMemory engine is just the first step (see Friday’s session). Then you need to apply this knowledge to DAX and understand why different DAX syntaxes for the same result might have different performance.
Understanding cross-filtering is a key to master DAX optimization. The more you know DAX, the more you will appreciate this session!

As I said before, the training day is an introductive course. If you already know DAX and want to improve your skills, there is a 3-day Advanced DAX Workshop I will teach in London on May 13-15, 2013. It could be also a good reason to visit London if you come from other countries!

Now that we are almost done with the PowerPivot for Excel 2013 book, we will write more articles – stay tuned!

#SSAS #Tabular Workshop and Community Events in Netherlands and Denmark

sqlbi — Thu, 12 Apr 2012 11:04:00 GMT

Next week I will finally start the roadshow of the SSAS Tabular Workshop, a 2-day seminar about the new BISM Tabular model for Analysis Services that has been introduced in SQL Server 2012. During these roadshows, we always try to arrange some speeches at local community events in the evening - we already defined for Copenhagen, we have some logistic issue in Amsterdam that we're trying to solve. Here is the timetable:

Netherlands

SSAS Workshop in Amsterdam, NL – April 16-17, 2012

2-day seminar, I and Alberto will be the trainers for this event, register here

We're trying to manage a Community event but we still don't have a confirmation, stay tuned

UPDATE: the community event has been comfirmed, please register here: http://passnl-april2012.eventbrite.com/

Denmark

SSAS Workshop in Copenhagen, DK – April 26-27, 2012

2-day seminar, I and Alberto will be the trainers for this event, register here

Community event on April 26, 2012

This event will run in Hellerup, at Microsoft venue
All details available here: http://msbip.dk/events/26/msbip-mode-nr-5/
People from Sweden are welcome! Just register to this private group on LinkedIn in order to announce your presence, so we’ll know how many people will attend

In community events we’ll deliver two speeches – here are the descriptions:

Inside xVelocity (VertiPaq)
PowerPivot and BISM Tabular models in Analysis Services share a great columnar-based database engine called xVelocity in-memory analytics engine (VertiPaq). If you want to improve performance and optimize memory used, you have to understand some basic principles about how this engine works, how data is compressed, and how you can design a data model for better optimization. Prepare yourself to change your mind. xVelocity optimization techniques might seem counterintuitive and are absolutely different than OLAP and SQL ones!

Choosing between Tabular and Multidimensional
You have a new project and you have to make an important decision upfront. Should you use Tabular or Multidimensional? It is not easy to answer, because sometime there is a clear choice, but most of the times both decisions might be correct, at least at the beginning. In this session we’ll help you making an informed decision, correctly evaluating pros and cons of each one according to common scenarios, considering both short-term and long-term consequences of your choice.

I hope to meet many people in this first dates. We have many other events coming in May and June, including an online event (for US time zones), and you can also attend our PreCon Day at TechEd US in Orland (PRC06) or TechEd Europe in Amsterdam. I’ll be a good customer for airline companies in the next three months!

I’m just sorry that I hadn’t time to write other articles in the last month, but I’m accumulating material that I will need to write down during some flight – stay tuned…
