Gartner 2010 Magic Quadrant for BI released

Uncategorized No Comments »

Noticed that Gartner’s MQ for Business Intelligence  is now out there for 2010:

Compared to 2009, it appears that Microsoft (yay!), Oracle, and MicroStrategy moved up and to the right in the leader’s quadrant.

Of all the players in the MQ, it looks like Actuate is the big loser – it made a pretty big move down and to the left in the niche quadrant.

Having problems unzipping the Contoso SSAS/OLAP backup file?

Sample Data No Comments »

There are reports that the SSAS archive out on http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=868662dc-187a-4a85-b611-b7df7dc909fc is corrupt….”damaged, truncated, or has been changed”, to exact :)

To open it, simply rename the cube zip file to Contoso_Retail.zip and then try again – happy OLAP-ing.

New large DW and OLAP sample databases available: Contoso!

For those of you who attended SQL PASS or other recent Microsoft-related technical conferences, you may have seen our new BI “Contoso” demo. Well, the data that powers it has now been made available for download. You’ll find both an OLTP DW and an OLAP cube for your data-munching pleasure.

 I haven’t had time to actually test-drive the dataset, but it is supposed to have millions of rows and be very real-world. Someone please download this thing and tell me how much data I have to look forward to playing with!??

Please?

$20,000 to create a single BI report? (or: Yeah, PowerPivot is cool, but it can save you bucks, too.)

PowerPivot, Project Gemini No Comments »

Over on the Forrester Blog, Boris Evelson has written an interesting post about the real cost of creating a single BI report in the enterprise. He estimates a price tag of between $1,840 and $20K per report after one factors in expenditures on software, services, salaries, hardware etc.

He suggests four general approaches to lowering BI costs, and PowerPivot neatly enables at least two of the four strategies.

Is PowerPivot a BI panacea? Nah, of course not. But intelligently leveraged, I believe the tool will drive down costs associated with creating BI reports.

PowerPivot, DAX and Semi-additive measures

PowerPivot, Project Gemini, SQL Analysis Services No Comments »

Over the week-end I was doing some analysis on SQL Server disk usage, and wanted to be able to display current disk usage by database. Up to this point, I’d mainly been doing a SUM over  my measures. Well, that would make no sense in this scenario – I’d end up with a meaningless number just like I would if I took a SUM of an Inventory value.

I found myself dealing with a classic semi-additive measure. These are easy to deal with using SQL Server Analysis Services, but a tiny bit trickier in PowerPivot.

I tried various DAX-related ideas, and some actually kind of worked, but Marius Dumitru, a co-worker at Microsoft, suggested the best solution.

I happen to have a date dimension which we could lean on for this challenge – I just needed to find the last “Disk Use” value that had been recorded. Since all of my readings are associated with a date, slam dunk!

Here’s what I did:

Created a calculated measure which SUMs the measure in my table (I named it “Sum Disk Size”):

     = SUM(‘Fact_DatabaseMetrics’[Disk Size])

Created a second calculated measure which filters the first, looking for the value related to the last associated date in my date dimension (via DAX’s LastNonBlank function) . I didn’t know you could filter a measure so easily!

        = ‘Fact_DatabaseMetrics’[Sum Disk Size](LastNonBlank(‘Dim_Date’[DatePK], ‘Fact_Database’[Sum Disk Size])

The second measure is what I added to my PivotTable.
