Have already used DAX?
Want to hear more about BIG DATA?
Use Excel?

5. What happened in the seventies?

6. 1978: Visicalc changed the world

7. 2009: PowerPivot was announced
Microsoft says:
One day, you will say: «I was there»
Alberto and Marco answer:
C’mon… you are clearly joking
Looks cool, but not a game changer
You are pushing Excel Hell again!
They need BI Professionals!
What about the one version of the truth?
That’s another useless tool in the BI arena

8. DAX: Data Analysis eXpressions
Programming Language
SSAS 2012 Tabular
PowerPivot for Excel 2012
Excel 2013 Data Model
Brand new
Language
Technology
Programming Attitude
Not using it, yet? C’mon… time to start!

9. Agenda Want to learn DAX?
Sorry… one hour is not enough
Really, believe me!
We’ll see what benefits DAX brings to the BI world
Seeing DAX in Action!
Excel 2013 new features for Self-Service BI
How Excel is changing the rules, again

10. The Scenario: AdventureWorks
Sells bikes all around the world
Already have a data warehouse
Need to perform analysis on data
Build a lot of reports
Share them with the colleagues
Using Excel 2013

11. The Data Warehouse
The data warehouse is a simple and standard one, after all we will build everything in an hour…
Sales
Dim Date
Dim Customers
Dim Products
Dim Categories
Dim Geography
European PASS Conference 2009

12. The project in good old style
Find a good BI professional
Start Visual Studio
Create the solution
Design dimensions and measure groups
Deploy on the server
We are not going to demo this
You already know UDM, don’t you?
Even if now it is called Multidimensional

13. Let’s Prototype in Excel

14. I Need to Count the Customers…
You want to count the customers?
DimCustomer is a dimension!!!
If only you told me that before…
Well, don’t worry, it can be done
I will create a new measure group
And setup a fact-relationship with customers
Not a big issue, just a couple of hours

15. I Need Just Another Count…
You want to count the buying customers?
That’s a DISTINCT COUNT over the fact table!
Well, yes, it can be done
It’s not easy, although…
I will create a new DISTINCT measure group
Then I will partition the fact table
Maybe review the clustered index of the fact table…
Otherwise it will be slow...

16. Hey, the numbers are wrong…
Ops… I counted CustomerKey
You wanted to count CustomerCode?
That’s not fair to say at this point…
All I need to do is
Bring CustomerCode in the fact table
Create a new measure group
Pay an ORDER BY during processing
And… please, don’t ask for any other DISTINCT COUNT!

17. Oh, well… while you are here…
Now you want to count the NEW customers???
What do you mean by that?
Customers who never bought anything
And are buying something now
It would be interesting…
Oh… well… let me search if there’s a blog post somewhere, somebody might have done it
Let’s talk later about that

18. I Need Some Banding Now Analysis by Price Range?
Freely configurable?
That’s not very easy at all
I need to compute range during ETL
That means updating the DWH structure Ops… it’s the fact table!
Then add a new dimension, that’s easy

19. ABC Analysis What’s ABC Analysis? Clustering technique
Helps detecting important products
Class
Percentage
A (few products)
70%
B (some products)
20%
C (many products)
10%
GRAND TOTAL
100%

20. ABC Analysis Usage
The ABC class is used to slice data

21. ABC Analysis with Excel

22. ABC in SQL SUM( Amount) GROUP BY Product INTO #temp
UPDATE #temp SET Percentage = RunningTotal on Product Amount / SUM( Amount )
UPDATE product SET Class = A/B/C (from #temp)
SQL
SQL
SQL

23. ABC in MDX Process Sales cube
MDX query on Sales cube to extract ABC Class
UPDATE product SET Class = A/B/C
from MDX query
Requires ETL or Linked Server
Process Product Dimension
Update Sales aggregations (ABC flexible attribute)
OLAP
OLAP
OLAP
SQL

24. Let’s build it together

25. Well, that was not easy… DAX is not easy?
Well… it is, in reality. But the solution is slightly complex to implement…
You want an Excel-only solution?
We can work on it…
Excel 2013 makes things easier for Excel gurus
Let us try it

26. I want a map chart!!! I’d like to build a report with a map
Pinpoint all the sales as coloured circles
Not very useful, but looks damn good!
I have seen this on a friend’s reporting system!

27. Wow… that map looks cool!
I need latitude and longitude
Maybe a geography column in the DWH?
Where do I start learning about it?
And how do I find latitude of Rome?
Not speaking about longitude…
Time to bing for a solution
You will need a charting component
Write some code to find coordinates
And finally mix everything together

28. Tabular and DAX Concepts
Simple Relational Data Model, not Dimensional
Tables
Relationships
Calculated Columns
Complex calculations stored in the data model
Incredible Speed
No need to change the data model
Simply leverage the tremendous speed of DAX
