How to bulk copy Azure ML Experiments from a Workspace to another one or do a Backup of them in Physical Files

Hi all,

today I want to tackle the issue of bulk copying more than one Azure ML experiment at once between different workspaces.

May be you already know that you can partially solve this task by copying an experiment one at a time. But you have to access to both the workspaces with your user. If not, you can simply share a workspace in this way:

Once you can see both the workspaces in your Azure Machine Learning Studio, you can simply select an experiment and than “Copy to workspace”:


and than you can choose the destination workspace:


A you can imagine… you can’t simply select more than one experiment and than copy all them:


Now suppose you have dozens of experiments and simply you don’t want to waste your time coping them all manually, or moreover you can’t have access to a shared workspace for security reasons. Is there a way to bulk copy your experiments? I’ll show you how to do that using few rows of PowerShell.


SSAS Tabular Modeling Article Series on SQL Server Pro Magazine

I’ve just finished a series of four articles for SQL Server Pro Magazine, along with sample projects and hands-on exercises. The series will take you through SSAS Tabular model design from start to finish, using the Adventure Works sample data in SQL Server 2012 or 2014.  Follow these links to each article in the series:

Part 1 – Getting Started with SSAS Tabular
Part 2 – Easy DAX – Getting Started with Data Analysis Expressions
Part 3 – Tabular Model Administration
Part 4 – Deep Dive DAX – Solving Complex Business Problems with Data Analysis Expressions

Power BI Workshop Videos

I’ve created a series of five tutorial videos for a set of workshops I’ll be doing at several events this year.  The workshop is available from an hour-long quick demo to a full-day, hands-on workshop with a hosted lab environment in the cloud.  The series teaches how to create a complete business intelligence solution using the components of Power BI in Excel 2013.  These video tutorials, although complete, are a subset of the entire workshop.  Each tutorial is about 10 minutes long.

New Power BI Preview and Pricing

Some exciting announcements were made today about the new Power BI cloud-based business analytics service.  Today Power BI is an add-on service for Office 365 that requires an enterprise-level license – about $50 per user per month.  Data transformation queries, data models and dashboard visualizations are all created using add-in tools for Excel 2013.  All of the content is managed in SharePoint Online.  The new Power BI designer and hosted dashboard elements won’t require any Excel add-ins and use a streamlined cloud service with a list of mobile options.  The best part is that the price also went way down – about $10/month for designers and it’s free for anyone who just runs reports and dashboards.  Yea… free!

How to resolve connection errors when loading data in SSAS Tabular project

This post actually applies to both multidimensional (cube) projects and Tabular projects which manage data source connectivity in a similar fashion.  The multidimensional design experience is different but the mechanics of the SSAS engine are essentially the same.

When loading data from a SQL Server data source into a Tabular model project, chances are very good that you’ll see an error on the first attempt.  I’ve been creating SSAS projects for over over 15 years and, even though this is a relatively simple process, I still usually work through the initial configuration in trial-and-error mode.  So, let’s call this a normal part of the process.

Power BI Semantic Model Supports Many-to-Many Relationships

Is is possible to duplicate the same many-to-many relationship behavior in VertiPaq that we have in SSAS multidimensional?

Since Tabular model projects were introduced in SQL Server 2012, one of the major blocking points for adaption has been the lack of out-of-the-box support for many-to-many relationships.  I’ve been using, demonstrating and showcasing SSAS Tabular and Power Pivot for at least three years and in that time it became apparent that, even though this might only be a perceived limitation in many cases, for quite a few enterprise IT shops; many-to-many support has become a litmus test for whether this technology is ready to be taken seriously.  Honestly most business data models don’t need many-to-many relationships to be useful but it is still a reality.  This week Chris Webb posted about bidirectional relationship support in the new Power BI designer and demonstrated an example using sales of fruit that can exist in different categories.  (more…)

Drill-through to Details from Reporting Services to Excel

Can an SSRS report be designed to drill-through to an Excel workbook in-context (showing only the same filtered detail data)? I have to admit that I have been chasing this solution for a few years now before I was motivated enough to work it through to a viable result. More than a few consulting clients have asked if it is possible to build a dashboard solution with the option to drill-through to transactional details in Excel. The answer has always been “well, sort of” …we could only drill-through to an SSRS report and then export the contents of that report to Excel. That answer usually wasn’t good enough for the Excel power users who need to create their own workbook formulas and calculations, and use other Excel formatting and features; like PivotTables, slicers and conditional visualizations. Over the past few years, I have used some clumsy work-around techniques and discovered things like: if the target workbook were published in SharePoint and managed in a web part, workbook parameters can be used with great effort to achieve this task. However, that option has not proven to be a practical solution in most cases. As my good friend Steve Eaton once said: “Anything is possible if you have a positive mental attitude, tons of money and supernatural powers.” I’ll admit that I’m short on two of the three but I do have persistence and I’m bull-headed enough to apply a little out-of-the-box thinking now and again. The technique I will demonstrate will work in a standard Reporting Services deployment with any edition of Excel on the desktop. (more…)

New Power BI stand-alone Designer, Dashboards, APIs & iOS App

This week Microsoft announced the availability of Power BI Dashboards and the browser-based dashboard designer.  What is it and why is it important?  The most significant thing about it is that report and dashboard users do not need to have Excel 2013 ProPlus edition or an Office 365 subscription to use Power BI.  This is very good news as it opens these amazing capabilities up to a much wider audience; those who work for companies that don’t have Office 2013 ProPlus or who are not using Office 365 ProPlus.  Power BI updates and new features are being released at a very fast pace and there is much to consider.  The definition of “Power BI” and Microsoft’s larger Business Intelligence and data analytics offering continues to evolve. First, exactly what’s new and recently available? (more…)
