Power BI Reports in SSRS Techinical Preview

/0 Comments/in /by

From the glimpse to the first public preview…it’s great to see one of most requested feature coming to life: ability to render online Power BI reports in on-premises SSRS. Alas, Microsoft is keeping us in suspense and no official date and release vehicles have been announced yet but we can now see and test it using the VM that Microsoft put on Azure (read the Chris Finlan’s steps to get started).

At this point, the integration supports only Power BI Desktop files that connect to Analysis Services (Multidimensional and Tabular). Attempting to deploy models connected to something else or with imported data, doesn’t work and you’ll get an error. Custom visuals and R visuals are not supported yet. For the most part, the integration is limited to report viewing only (similar to what you get if you embed Power BI reports in Power BI Embedded). That’s will be probably fine to start with but it will be nice to have Q&A, Quick Insights, Analyze in Excel, and ability to create custom reports online.

It’s great that Microsoft decided to expose the connection string as a regular SSRS data source. This will allow you to change the credentials settings, such as to impersonate the user when Kerberos is not an option and the SSAS is on another server. When the Power BI Desktop file is uploaded, it’s saved in the report catalog as any regular SSRS report (now referred to a paginated report). This means that you secure and manage Power BI reports the same way you work with paginated reports. Speaking of management, I hope that at some point Microsoft will add support for subscriptions and caching. What’s need is unification among the four types of reports: paginated, mobile, Power BI, and Excel. While waiting, we get a handy bonus feature: ability to add comments to reports, such as to get someone to formally approve what they see on the report.

Everyone is asking about SSRS support for Power BI reports. Progress has been make and I hope it won’t be long before we get the real thing.

The Future of Microsoft Logical Data Warehouse

/0 Comments/in /by

Let’s face it, the larger the company, the more difficult is to achieve the dream of single enterprise data warehouse (EDW). In a typical mid-size to large organization, data is found in many data repositories and integrating all this data is difficult. I’m doing an assessment and strategy engagement now for a unit in a large organization, and they need access to at least 10 other on-premises systems, including two very large repositories. Naturally, they don’t want to import all of this data, which could be millions of rows per day, and recreate their own copy of these large corporate repositories. So what to do?

In my “QUO VADIS DATA WAREHOUSE?” newsletter, I defined a logical data warehouse (LDW), also known as data virtualization, is an emerging technology that allows you to access the data where it is. Don’t we have linked servers in SQL Server that do this? We do and they might work to a point. But what if you want scale out distributed queries to achieve better performance? In today’s SQL PASS SUMMIT keynote, Day 1 Keynote “A.C.I.D. Intelligence” (A.C.I.D stands for Algorithms, Cloud, IoT, Data), Rohan Kumar showed something that I think it’s very important and it deserves much more attention than occasional references in blogs. It showed where Microsoft is bringing PolyBase and how this technology could be the Microsoft implementation for data virtualization.

In SQL Server 2016, PolyBase allows you to access data in on-premises Hadoop cluster and in Azure Blob Storage. For example, you can store some files in HDFS and define an external PolyBase table. Then, you can have a query with heterogeneous join between a local SQL Server table and the external table. Rohan showed that Microsoft will extend PolyBase to other popular SQL and NoSQL databases. More importantly, it showed that just like an MPP appliance, such as Microsoft Analytics Platform System (APS) or Azure SQL Data Warehouse, a SQL Server node would allow you to combine multiple SQL Server instances as compute notes so that you scale out access to these data sources. For example, if you have two SQL Server compute nodes and you use PolyBase to access an Oracle database, you’ll be essentially spreading the query across these nodes in parallel and then combine the results. Of course, just like linked servers, there are technical challenges, such as cases where SQL Server might need to move data to the other node. Rohan mentioned that the SQL Server query optimizer will have smarts to optimize heterogeneous joins.

If you’re in the market for a logical data warehouse vendor, don’t rule out Microsoft. Stay tuned for more news around PolyBase and the investments Microsoft makes in this area after the Metanautix acquisition.

Azure Analysis Services

/0 Comments/in /by

Despite the mantra you might hear elsewhere, my experience shows that the best self-service BI is empowering users to create reports from trusted semantic models sanctioned and owned by IT. Most of the implementation work I do involves Analysis Services in one form or another. Analysis Services has a very important role in your BI ecosystem as I explain in the “Why Semantic Layer” newsletter.

Today, at the SQL PASS SUMMIT, Microsoft announced that Analysis Services Tabular is now available as an Azure PaaS service. As a participant in the prerelease program, I had the opportunity to test Azure Analysis Services and this is why I believe you should care:

  1. If you develop cloud-based solutions, you might not have to provision a VM for Tabular anymore. Instead, you can provision an Analysis Services cloud service in seconds, just like you can provision an Azure SQL Database.
  2. You can easily scale up or down Azure Analysis Services, just like you can do this with Azure SQL Database. You can even pause it so that you don’t incur cost.
  3. You don’t have to set up a gateway for SSAS. You can use Power BI Desktop to connect to Azure Analysis Services and deploy the report to Power BI. However, you would need a gateway if your source data resides on premises so that you can process the model with on-premises data. Note that currently you can’t use Power BI Get Data to connect to Azure Analysis Services directly from Power BI. Instead, you must use Power BI Desktop.
  4. The service is highly available by default. SQL Server pros implementing highly available solutions know that this is not easy and not cheap. So, factor in high availability if you find Azure Analysis Services pricing is too high.

On the downside, as it stands Azure Analysis Services uses Azure Active Directory for security and it doesn’t support claim authentication. Power BI users will be able to authenticate but not Power BI Embedded (not yet).

Currently in preview, Azure Analysis Services is a very important addition to the Microsoft Azure BI stack that allows BI pros to implement cloud-based semantic models as they can currently do on premises.

Automating Power BI Desktop Refresh

/4 Comments/in /by

Power BI Desktop is becoming an increasing popular tool for self-service reporting. But it has a glaring gap. Unlike Excel, it doesn’t currently support an object model for automating tasks. Yet, there are a variety of scenarios that call for task automation, such as refreshing imported data. For example, one customer wanted to show a Power BI Desktop dashboard on a shared monitor that will refresh itself periodically. In another scenario, an ISV wanted to automate the data refresh because Power BI Embedded doesn’t currently have APIs to support a scheduled refresh.

Currently, there is no supported way to refresh Power BI Desktop files automatically. However, you can try the following approaches at your own risk:

  1. Use the Michal Dúbravčík’s PBIXRefresher script. This is a PowerShell script that opens Power BI Desktop and sends a key to the Refresh button.
  2. Shell out to open Power BI Desktop with the file you want to refresh (pbidesktop.exe <filepath to pbix file>). Then, find programmatically the port that the PBI SSAS listens on (see my “Upgrading Power BI Desktop Models to Tabular” blog on this subject). Then, use AMO or the new Tabular Object Model to send a process script command.
  3. Use the commercial Power Update tool, which is capable of refreshing Excel Power Pivot workbooks and Power BI Desktop files.
