The Power BI team have released details of their March update to the standalone Power BI designer.
You’ll find details of the update here: http://blogs.msdn.com/b/powerbi/archive/2015/03/26/7-new-updates-to-the-power-bi-designer-preview-march-2015.aspx
The first thing I noticed is just how much faster the tool operates. The blog post mentioned performance enhancements but I really, really noticed them.
One particular enhancement that I wanted to call out was the additional of a connector for Google Analytics. I’ve been trying that this morning and have found it really easy to use. All the standard categories appear as available sets of data:
I’ve picked those that I’m interested in:
Then added them to a report:
Very easy. And it’s clear which type of device/operating system we need to continue to ensure the best experience on at SQL Down Under.
Two of the parameters in SQL Server connections are the Application Name and the Host Name. You can see these in SQL Server if you execute the following command:
I’ve always been a fan of having applications identify themselves in their connection strings. It makes tasks like tracing much easier. The tools supplied with SQL Server do a reasonable job of that as you can see above. But many other tools don’t do such a good job.
I was working at a site today where they are using Powershell to execute commands for monitoring. I noticed that the Powershell commands did not set the Application Name in the connection string when using Invoke-Sqlcmd. Note the following example:
I then tried to work out how to set the Application Name. When I checked the documentation for Invoke-Sqlcmd, it shows that the Hostname is set via the SQLCMD option –H, by using the –Hostname parameter.
However, note that if you use the –Hostname option, it actually sets the Application Name and does not set the Host Name:
Over the last year, I’ve delivered a number of partner enablement events for Microsoft. These events are low cost training sessions that run for three days. Days 1 and 2 cover SQL Server 2014 content, mostly regarding in-memory OLTP, clustered columnstore indexes, and Azure integration with hybrid systems. Day 3 covers the full Power BI stack.
We’re pleased to be running another set of these around the country:
Melbourne: November 5th to 7th
Perth: November 24th to 26th
Sydney: December 8th to 10th
I’d love to see many of you there. I’m looking forward to delivering them. To find out more, follow these links:
It seems like anyone that’s talked to me this year has heard me going on and on about how Power Query is just the nicest new bit of tech that’s come from Microsoft lately. We cover it as part of our one-day Power BI Core Skills training class and as part of day 2 in our BI Core Skills classes that we recently updated for SQL Server 2014. Out of all the technologies that people see during that week, Power Query is the one that seems to promote the biggest discussions.
It’s also a product that keeps getting improved constantly. Another new update for Power Query is out and you can find it here: http://www.microsoft.com/en-us/download/details.aspx?id=39379&WT.mc_id=Blog_PBI_Announce_DI
Here is a video that shows what’s been updated: https://www.youtube.com/watch?v=Q9boOzu298Q
The blog post from the team that shows what’s changed is here: http://blogs.msdn.com/b/powerbi/archive/2014/06/26/6-new-updates-in-power-query-june-2014.aspx
For me, the one big thing that Power Query is now missing is a corporate story beyond Excel/Power BI. The queries that you create in Power Query are actually M language queries. This is a very capable language (unrelated to what the industry used to call the M language), that Microsoft have documented here: http://go.microsoft.com/fwlink/?LinkID=320633
I would so love to be able to take the queries that I generate in Excel and paste them into an SSIS data source, or use them as a data source in SSAS tabular. Once those types of options appear (surely they must), this is going to be even more of a killer application.
I promised there would be a bunch of shows this year. The second one is now published.
In this show, SQL Server MVP Grant Paisley describes PowerPivot, Power View, Analysis Services Tabular vs Multidimensional and shares the lessons he’s learned when working with these tools.
The show is here: http://www.sqldownunder.com/Resources/Podcast.aspx
When Power View appeared, one of the big outcries was “but what about connecting to existing cubes!”.
Great to see that the SQL Server team have addressed that. A CTP that allows connecting Power View to SSAS Multidimensional cubes is now available:
Help the team get this out the door by trying it and providing feedback.
I’ve been doing some work with PowerPivot and SharePoint/Excel Services this week. I wanted the user interface to have slicers for:
But I wanted the slicer to be preselected for the current month. There is no property on the slicers to set a default value. I read a number of websites and the suggestion was to use VBA code to set the value. This works but if you want to have the VBA code run at workbook open, you have to create a macro-enabled workbook, and these are not supported by Excel Services.
So I seemed to be fresh out of luck. However, one of my Spanish colleagues José Quinto Zamora came to the rescue. All you need to do is to select the slicer filter value that you want as the default, before you save the workbook, and every time you open the workbook, the slicer value will be already selected. That’s as good as a default value for me. Thanks José!
Hope this helps someone else.
I’m loving my Kindle. I seem to be getting through books so much faster. One book that I recently read was Book Review: Microsoft PowerPivot for Excel 2010: Give Your Data Meaning by Marco Russo and Alberto Ferrari.
I really liked this book. It provided quite good coverage of PowerPivot use in Excel 2010 and also spent some time mapping the use of PowerPivot to organizational requirements. Marco and Alberto provided more coverage of DAX (Data Analysis Expressions) than I have seen anywhere else, particularly in relation to the CALCULATE verb.
If I have any criticism of the book, it’s probably just the order of the chapters. I can imagine that many people won’t want to delve so deeply into DAX and may stop reading before they get to the later chapters. I’d like to have seen much of the DAX material at the back of the book as a type of “advanced DAX topics” section, given that the remainder of the book doesn’t really depend upon it.
I was left feeling that there’s a need for another type of DAX book, much like the book that Art Tennick wrote for MDX: Practical MDX Queries: For Microsoft SQL Server Analysis Services 2008. In that book, Art provides a large number of “recipes” for how to achieve common tasks with MDX. I’m sure that’s also needed for DAX.
Anyway, Marco & Alberto’s book is definitely recommended.I’d give it 8 out of 10. (And a big thumbs up to the publisher for making a Kindle version available too).
