My PASS Summit 2013 Presentations

PASS_2013_SpeakingButton_180x180-1I had the honor to speak for the first time at this past PASS Summit 2013 in Charlotte, NC. It was a great opportunity for me as this is one of the most prestigious nationwide conferences on SQL Server. I delivered 3 different sessions on Business Intelligence related topics. Attendance to my sessions exceeded my expectations and my overall experience as a first-time speaker was very positive. I also need to add that the God’s of the live demos were on my side.

My session titled PowerPivot + Power View = Self-service BI Revolution was full and had about 5 to 8 people standing in the back. Everybody got excited when I did a demo of the nice interactivity in Power View and 3D geographical capabilities of PowerMap.

The Lightning Talk room was packed and people had to be turned away. This room should be bigger next time as these Lightning Talks are very popular. Everybody accepted and agreed with my postulation on the need for Conformed Stored Procedures in addition to Conformed Dimensions and Facts. After the Lightning Talks were over, several attendees came forward to discuss further how Conformed Stored Procedures should be implemented. One attendee in particular, mentioned that he had been thinking about proposing a similar approach to his team and this talk helped him get re-assurance of this approach.

My last session on SSAS Hierarhcies Tips & Tricks was a half-day session on the last day of the summit between 2:00pm and 5:00pm. It was half-full for the first half of the session, and ended up about 1/4 full.  This drop-off is expected towards the end of the Summit as many people fly back home on Friday and usually leave around 4:00pm.

I’m very pleased with the turnout and feedback received. The audience in all of my sessions was very engaged and had a lot of great questions. I definitely look forward to speak at PASS Summit 2014 in Seattle, WA and at PASS BA Conference 2014 in San Jose, CA.

Configuring BIDS 2008 / 2008 R2 and Visual Studio 2008 to work with Database & Business Intelligence Projects and Team Foundation Server (TFS)

Working with the SSIS, SSAS, and SSRS Business Intelligence projects along with Database projects in the same Visual Studio 2008 development environment can be challenging as there is no clear documentation how to enable both set of projects.  Database projects are supported by Visual Studio 2008 Developer, Professional and Team System Database Editions. The  SSIS, SSAS, and SSRS Business Intelligence projects are supported by the Visual Studio 2008 shell that comes with SQL Server 2008 / 2008 R2.

If you have BIDS 2008 / 2008 R2 installed by itlself and you try to open a database project you get an error saying that this type of project is not supported. You get the same error if you have Visual Studio 2008 installed by itself and try to open one of the Business Intelligence projects. The reason behind these errors is that BIDS 2008 / 2008 R2 does not come with the database project template and Visual Studio 2008 does not come with the SSIS, SSAS, and SSRS Business Intelligence project templates.

So how do you get both set of templates in a single development environment?

In order to get both set of templates in the same development environment, you need to install both Visual Studio 2008 and BIDS in the right order as described in the following steps:

  1. Uninstall all of these if you already have them installed in your environment:
    – Visual Studio 2008
    – BIDS 2008 / 2008 R2
    – Team Explorer 2008
  2. Install Visual Studio 2008
  3. Install Visual Studio 2008 Service Pack 1
    http://www.microsoft.com/en-us/download/details.aspx?id=10986
  4. Install BIDS from your SQL Server 2008 / 2008 R2 installation media

At this point should have a working Visual Studio environment with both set of projects.  A quick way to verify that the installation was successful, is to take a look at the Visual Studio version in the Help|About page. It will show as Version 9.0.30729.4462 QFE as shown in the picture below. QFE stands for Quick Fix Engineering.

VS2008QFE

When you launch Visual Studio 2008 or BIDS 2008 / 2008 R2 you will be prompted to select the default environment settings. Since I work with the Business Intelligence projects most of the time, I select the Business Intelligence environment. This is an option presented only the first time you open Visual Studio. To change this setting, use the Import and Export Settings wizard, which is available on the Tools menu. For more information on choosing and changing the environment settings go to http://msdn.microsoft.com/en-us/library/6k364a7k(v=vs.90).aspx.

Connecting to TFS 2005 and 2008

To connect to TFS 2005 and 2008 you will need to download and install Team Explorer 2008 from http://www.microsoft.com/en-us/download/details.aspx?id=16338.

If your end goal is to be able to work with database projects, business intelligence projects and connect to TFS 2005 or TFS 20008 the complete steps are as follows:

  1. Uninstall all of these if you already have them installed in your environment:
    – Visual Studio 2008
    – BIDS 2008 / 2008 R2
    – Team Explorer 2008
  2. Install Visual Studio 2008
  3. Install Visual Studio 2008 Service Pack 1
    http://www.microsoft.com/en-us/download/details.aspx?id=10986
  4. Install BIDS from your SQL Server 2008 / 2008 R2 installation media
  5.  Install Team Explorer 2008
    http://www.microsoft.com/en-us/download/details.aspx?id=16338.

Connecting to TFS 2010

In some cases, the solutions & projects are 2008 / 2008 R2 projects but the repository is TFS 2010 or TFS 2012. Even if you installed Team Explorer 2008 you will get an error when trying to connect to a TFS 2010 or TFS 2012 server. The reason for this is due to the fact that Team Explorer 2008 does not support full URL paths (i.e. https://myservername/mytfs/mycollection) in the TFS server name section.

To fix this issue you will need to download and install the Forward Compatibility Update Team Explorer 2008 SP1 for Team Foundation Server 2010 (http://www.microsoft.com/en-us/download/details.aspx?id=10834).

Notice that this update can only be applied to Team Explorer 2008 SP1 (Service Pack 1). The curve ball here is that there is no Team Explorer 2008 SP1 available  as a download. In order to turn Team Explorer 2008 into Team Explorer 2008 SP1 is to apply the Visual Studio 2008 SP1 to it. This means that if you followed steps 1 to 4 above, you will need to repeat Step 3 (Re-install Visual Studio 2008 SP1).

If your end goal is to be able to work with database projects, business intelligence projects and connect to TFS 2010 the complete steps are as follows:

  1. Uninstall all of these if you already have them installed in your environment:
    – Visual Studio 2008
    – BIDS 2008 / 2008 R2
    – Team Explorer 2008
  2. Install Visual Studio 2008
  3. Install Visual Studio 2008 Service Pack 1
    http://www.microsoft.com/en-us/download/details.aspx?id=10986
  4. Install BIDS from your SQL Server 2008 / 2008 R2 installation media
  5. Install Team Explorer 2008
    http://www.microsoft.com/en-us/download/details.aspx?id=16338
  6. Re-install Visual Studio 2008 SP1
  7. Install the forward compatibility update for Team Explorer 2008 SP1 for Team Foundation Server 2010
    http://www.microsoft.com/en-us/download/details.aspx?id=10834

Connecting to TFS 2012

To connect to TFS 2012 the following update is required :

Visual Studio 2008 SP1 Compatibility GDR for Visual Studio 2012 Team Foundation Server and Team Foundation Service Preview (http://www.microsoft.com/en-us/download/details.aspx?id=29983).

If your end goal is to be able to work with database projects, business intelligence projects and connect to TFS 2012 the complete steps are as follows:

  1. Uninstall all of these if you already have them installed in your environment:
    – Visual Studio 2008
    – BIDS 2008 / 2008 R2
    – Team Explorer 2008
  2. Install Visual Studio 2008
  3. Install Visual Studio 2008 Service Pack 1

Hopefully this post helps you get your environment all squared away.

Presenting 2 sessions at SQLPASS

I’m truly honored to be chosen to speak at PASS Summit 2013. The honor is compounded as I have been chosen to deliver two sessions:

SQLJoePresentingSummit

  • Fast Performing SSAS Hierarchies: Tips and Tricks (3 hours)
    Track: BI Platform Architecture, Development & Administration
    Session Abstract: Depending on how they’re implemented, SQL Server Analysis Services hierarchies can be the source for a very high performing OLAP cube or the culprits of long running analysis. Are you implementing SSAS hierarchies correctly?This half-day session will walk you through how to implement SSAS hierarchies the right way and show you some tips and tricks to make them perform faster. You’ll also learn how to query and navigate SSAS hierarchies using common MDX functions.
  • PowerPivot + Power View = Self-Service BI Revolution(75 minutes)
    Track: BI Information Delivery
    Session Abstract: The status quo has changed. IT is no longer required for business intelligence. End users can do their own BI within the comforts of Excel and SharePoint. Sound threatening? Maybe freeing? In this session, get to know what your role is and could be in this new self-service delivery model. You’ll also learn how PowerPivot and Power View work, how to leverage them, and how to make them fit into your enterprise data warehouse.

I feel very fortunate to be chosen as a speaker and to be able to give back to the community at a much bigger scale. I hope to instill my passion for the community and to be a relevant source of learning at PASS Summit 2013 to all who attend my sessions.

I encourage you to join me and attend PASS Summit 2013 in Charlotte, N.C. from Oct. 15th to 18th. There are more than 190 sessions to attend. We will also host  12 full-day pre-conference sessions on Oct. 14th and 15th with top SQL Server gurus.

For more information visit: http://www.sqlpass.org/summit/2013/

In addition to speaking at PASS Summit 2013, I am planning to speak and attend the SQL Saturday #237 Charlotte, N.C. BI Edition which will be hosted Saturday Oct. 19th following PASS Summit 2013 week.

For more information about SQL Saturday #237 Charlotte, N.C. BI visit: http://www.sqlsaturday.com/237/eventhome.aspx

I hope to see you there!

The affordable self-service BI revolution has started.

I am officially announcing that I have now become an independent consultant and business owner. Becoming independent has always been my dream and I have now decided to follow that dream. I believe it is the right time to do it for my family and myself. It’s time to soar!

Why did I leave Pragmatic Works?

Simple. I wanted to follow my career goals and carve my own path. It was a hard decision to leave Pragmatic Works as I really enjoyed the work environment and had great relationship with the top brass Brian Knight, Adam Jorgensen, and Sam Washburn as well as my co-workers. The folks at Pragmatic Works gave me a lot of opportunities to learn and grow for which I am forever grateful. It is a great company to work for and highly recommend working for them. I would return to work for them in a heartbeat.

What are my plans?

First of all, I have created a corporation, called Agile Bay, Inc. (http://www.agilebay.com) through which I will be providing Business Intelligence consulting services, Software Development, Training and Staffing services. I will also be doing contract work and hiring BI and Software developers to take on some of these jobs.

My plan is to focus on self-service Business Intelligence solutions using the Microsoft toolset, including:

  • SQL Server Database Services
  • Analysis Services
  • Reporting Services
  • Master Data Services
  • Data Quality Services
  • SharePoint
  • Performance Point
  • PowerPivot
  • PowerView
  • & more…

I will continue leading, volunteering and sharing my knowledge in the SQL Server and Business Intelligence community and in PASS.

Enter the affordable self-service BI revolution

The new release of SQL Server 2012 will bring a lot to offer in the BI space. I truly believe it will be a game changer and many companies will embark in new Data Warehouse, Business Intelligence and Master Data Management projects. Some of these projects may have been put on hold due to licensing and development costs. This is where SQL Server 2012 will shine as it introduces lower BI licensing costs with the new SQL Server Business Intelligence Edition. Organizations will no longer require Enterprise Edition to do all the cool things Microsoft has to offer with their BI suite.

Additionally, the shift to the BI Semantic Model and the focus on self-service BI will open a lot of doors to consulting firms with lower overhead like mine. Enter the affordable self-service BI revolution!

Hitting the ground running

I am very grateful to the fact that the word has spread out among my immediate professional network and have already been booked for projects and contract work several months ahead.

I have tried not to market myself or my company too much during this initial phase as I want to manage my growth more organically. I am in the process of hiring BI developers at all levels, so if you are interested feel free to contact me via http://www.agilebay.com/#!contact.

 Mission

My mission is to empower individuals and organizations through the Microsoft Business Intelligence Toolset.

Vision

My vision is to be the catalyst and leader of the affordable self-service Business Intelligence revolution.

Value proposition

There are many alternatives available when chosing a consulting firm to help you achieve a succesful Business Intelligence, Data Warehouse and Master Data Management implementation.  My value proposition is to achieve this same success at an affordable budget and by providing you with the knowledge transfer and mentoring needed to continue your own development efforts.

The sales pitch

 You need an experienced and expert professional to help you with your design and development efforts.  I have experience and expertise. Let’s talk.

You may contact me through my company’s website at http://www.agilebay.com/#!contact or through email: info@agilebay.com

I’m also available for any quick help through email at jchinchilla@sqljoe.com. Make sure to check out my blog at http://www.sqljoe.com as well.

Using Unary Operators to control Analysis Services hierarchy aggregations

Analysis Services hierarchy aggregations can be easily controlled using unary operators. For example, in accounting there are GL accounts that are grouped in major GL account groups and used in different financial statements like Profit & Loss Statement, Income Statement, Trial Balance, and Balance Sheet. These GL accounts may affect the balances of the major GL account groups and  financial documents differently, adding  or subtracting to the balance.

A simpler example, might involve sales quotas for a Sales Department. For example, in some organizations the Sales Department is broken down into sales teams with salespeople assigned to those teams. The overall Sales Department quota is broken down into smaller quotas among these sales teams and the sales team’s quota is then broken down into quotas assigned to the team members. In some organizations, Sales Managers often assign these quotas evenly throughout the sales teams and sales team members. Others, in order to guarantee a fat bonus check decide to raise the bar and assign sales quotas that are higher to the overall department’s sales quota. Figure 1 below shows an organizational structure chart of our sample Sales Department with sales quotas that don’t sum up evenly.

Figure 1. Sales Department organizational structure chart and sales quotas

As can be seen in Figure 1, the total Sales Department quota is $150,000. The Sales Manager in this case decided to push their teams harder and assigned a sales quota of $60,000 to each team. In a perfect scenario, if all sales teams meet their sales quota, the total sales for the Sales Department would be $180,000, which is $30,000 more than the department’s sales quota. Accordingly, each team, in order to impress their Sales Manager and win a free meal and margaritas at the local Mexican joint, decided to exceed the team’s sales quota by assigning higher personal sale quotas.

In our BI solution, we are required to create an Analysis Services cube in which the Sales Manager can track these sales quotas at each level of the Sales Department organizational chart as seen in Figure1. But, we cannot simply sum up the sales quotas, because the totals would not match up. We could approach these several ways, but our requirement is to replicate Figure 1 with a single “SalesQuota” measure with no MDX or additional measures involved.

The Solution

In order to achieve the requirement imposed above we can make use of a special attribute property in Analysis Services called UnaryOperatorColumn to control how level members of our hierarchy contribute to the aggregated value of the level parent.

In a regular scenario, the parent’s sales quota at each level would be equal to the sum of its children’s sales quota. That would have been the case if the Sales Manager in our example had decided to distribute the overall Sales Department quota equally among each sales team and the individual sales team members would have done the same for their personal sales quota. In other words, each sales team’s quota would have been $50,000 each ($150,000 / 3). For Sales Team A, for example, each sales person’s quota would have been $16,66.67 each ($50,000 / 3).

But in our scenario, the parent’s sales quota at each level should not be equal to the sum of its children’s sales quota. The only solution then, is to create an “artificial” child at each level that holds the parent’s sales quota and specify this “artificial” child to be the only child contributing to the parent’s total. This is possible through the UnaryOperatorColumn attribute property in the Dimension designer in BIDS. In Figure 2 you can see the available Unary Operators that can be used in this property along with the resulting behavior as described in Books On Line (http://msdn.microsoft.com/en-us/library/ms175417.aspx).

Figure 2. Unary Operators.

The UnaryOperatorColumn attribute property value, as the name implies, is a pointer to a table column that holds one of the Unary Operators listed in Figure 2. For our Sales Department quotas example, we would need a column that holds the unary operator for each level member in our Sales Department dimension. The Sales Department dimension source table would look as shown in Figure 3.

Figure 3. Sales Department dimension source table

Notice that this table is a naturalized Parent Child table. Also, notice that an “artificial” child was created with the same name as its parent. This “artificial” child is the child that will hold the parent’s sales quota value and is the only value that will be used in the parent aggregation. The way we control this aggregation, is by assigning to this artificial child the ‘”+” Unary Operator and the rest of the children the “~” Unary Operator.

At the lower level in our hierarchy all the way to the right in Figure 3, each sales person is assigned a “~” as its Unary Operator  in the SalesPersonUnaryOperatorColumn and only the “artificial” child receives a “+” as its Unary Operator. The same applies for the Sales Team level in our hierarchy, only the “artificial” child is assigned the “+” Unary Operator.

The FactSalesQuota table that holds the sales quotas would look as shown in Figure 4:

Figure 4 FactSalesQuota fact table

The Analysis Services project

Once we have defined our underlying table structure, we can take a look at the Analysis Services project. Figure 5 shows the basic project definition with the Sales Department Dimension and Sales Quota measure.

Figure 5. Analysis Services project definition

The Sales Quota Measure

The sales quota measure is a straightforward column based measure. It is based on the Fact Sales Quota table and is a simple SUM aggregation. Figure 6 shows the sales quota measure definition.

Figure 6. Sales Quota measure

The Sales Department Dimension

The Sales Department dimension is a simple dimension with the necessary attributes needed to design a drilldown hierarchy. Figure 7 and 8 show the Sales Department dimension definition, user hierarchy and attribute relationships.

Figure 7 Sales Department definition

Figure 8 Sales Department attribute relationships

A very important step in any user hierarchy definition is to specify the key columns at each level. In this case, the only attribute that needs a composite key column definition is the Sales Team attribute. The key column definition is shown in Figure 9.

Figure 9 Sales Team attribute key columns

The deployed cube with the Sales Department definition provided so far would look as shown in Figure 10.

Figure 10. Deployed cube

Notice that the “artificial” children show up and that the children’s sales quotas are being added to the parent’s aggregated amount. To fix the aggregation issue we need to define the UnaryOperatorColumn attribute properties for the children level members. We can hide the “artificial” children by changing the HideMemberIf user hierarchy level property to Parent.

Figure 11 and 12 show the values for the UnaryOperatorColumn property for the Sales Person and Sales Team attributes.

Figure 11. Sales Person UnaryOperatorColumn value

Figure 12. Sales Team UnaryOperatorColumn value

Figure 13 and 14 show the user hierarchy level property HideMemberIf

Figure 13 Sales Person user hierarchy level HideMemberIf property

Figure 14 Sales Team user hierarchy level HideMemberIf property

The Results

Once these properties have been changed the resulting deployed cube should look exactly as required. Figure 15 shows the exact aggregation behavior as in Figure 1.

Figure 15 Final results

Conclusion and Considerations

The solution presented above provides the exact results as dictated by our requirements and is meant as a means to exemplify and understand how unary operator can be used to control aggregation behaviors in user hierarchies.

There are other options to provide the same results, but this solution requires no calculated members or MDX at all. While this solution works, you need to keep in mind that there are some performance consideration regarding unary operators and parent child hierarchies. The key is always to TEST! TEST! TEST!

Afterthoughts: SQL Saturday #79 South Florida 2011

This past Saturday August 13th I presented two sessions at SQL Saturday #79 hosted by the South Florida SQL Server User Group (SFSSUG) (Webpage | LinkedIn| Twitter). The first presentation was at 11:00am titled “So, What is BI Semantic Model and why should you care?” and the second one was at 3:00pm titled “Designing  and Optimizing Analysis Services Hierarchies.” I had an amazing time chatting with some old friends that made it to South Florida all the way from Charlotte, NC, Atlanta, GA and  several other Florida cities like Jacksonville, Pensacola, Orlando, and Tampa.

The Driving Adventure

It was an adventure to get there as I decided to make the 4-hour drive from Tampa, FL (about 500 miles round-trip) early in the morning. My original plan was to start my drive around 4:30am but due to being jet lagged from my midnight flight the day before, I woke up until I snoozed the alarm for the 3rd time around 6:30am. That gave me a 30 minute window to get there on time for my 11am session.

The Event

The event was well put together by it’s organizers and volunteers. The food was great and included a mix of Mexican goodies. The Nova Southeastern University Carl DeSantis Building was a great venue. I really liked the central atrium where everybody converged in between sessions and was more than ideal for having lunch and event wrap-up. Great choice of venue & food!

The Attendees

One Mountain Dew + a 5-hour energy bottle and a speeding ticket later, I managed to get there with 20 minutes to spare. My first session titled What is BI Semantic Model and why should you care? started on time and was packed. It was literally standing room only. I had a great time with the audience. They were very engaged and asked both technical and philosophical questions. A couple speakers and friends attended such as my “tweep” (tweeter peep) Phillip Rosen (LinkedIn | Twitter) whom I got to know him in person for the first time. Also, the amazing Data Mining expert and newly minted Microsoft MVP Mark Tabladillo, Ph.D. (Blog | LinkedIn | Twitter) with whom I exchanged a couple of good jokes and funny moments during the presentation. The most memorable being the conception of the term “Bingle” which is the abbreviation of Bing and Google.

Sanjay Soni, Microsoft TSP

One of the attendees was Sanjay Soni (LinkedIn), Microsoft’s new Data and BI Platform Technology Solution Professional (TSP) for the Greater Southeast District (Florida). Sanjay introduced himself after the presentation and was very kind to provide very positive feedback for my BISM presentation. We  spent some time chatting about opportunities to co-present and network some more. I’m very excited to assist Sanjay  as much as I can in his new role in Florida. I encourage for you to network with Sanjay as he is a very friendly and approachable guy. You will see him very soon at a user group or event near you!

At the end of my session several other attendees came up to introduce themselves personally. There were so many I almost ran out of business cards. I appreciate when attendees take a moment to chat with me after my sessions and get the opportunity to listen to their feedback and kind words. I feel truly honored to have been able to present to such a great crowd.

So, What is BI Semantic Model and why should you care?

In this presentation, I did an overview of the new Business Intelligence Semantic Model (BISM) and the new “flavor” of the Analysis Services Engine that Microsoft will release with SQL Server Codename Denali. I explained about the new focus on “Personal BI” with the PowerPivot add-in for Excel, “Workgroup BI” with PowerPivot for SharePoint and “Enterprise BI” with Analysis Services UDM and Tabular mode. I showcased the free PowerPivot add-in for Excel 2010 and later demonstrated how easily a PowerPivot workbook can now be turned into an enterprise grade Tabular database using the new Business Intelligence Development Studio in SQL Server Codename Denali and how simple it is to deploy them.

Designing  and Optimizing Analysis Services Hierarchies

 

On my second presentation Designing and Optimizing Analysis Services Hierarchies I also had a great time interacting with the attendees. The session was designed as an intermediate session but changed it a little bit to more beginner level from the results of my skillset level audience survey. I had great questions and participation from the attendees.

Thanks to everyone who attended my sessions and to the organizers and volunteers that made SQL Saturday #79 a success!
