Data Warehouse from the Ground Up at SQL Saturday Orlando, FL on Oct. 10th

SQL Saturday #442SQL Saturday #442 is upon us and yours truly will be presenting in Orlando, Florida on October 10th alongside Mitchell Pearson (b|t). The session is scheduled at 10:35 AM and will last until 11:35 AM. I’m very excited to be presenting at SQL Saturday Orlando this year as it’ll be my first presenting this session in person and my first time speaking at SQL Saturday Orlando! If you haven’t registered yet for this event, you need to do that. This event will be top notch!

My session is called Designing a Data Warehouse from the Ground Up. What if you could approach any business process in your organization and quickly design an effective and optimal dimensional model using a standardized step-by-step method? In this session I’ll discuss the steps required to design a unified dimensional model that is optimized for reporting and follows widely accepted best practices. We’ll also discuss how the design of our dimensional model affects a SQL Server Analysis Services solution and how the choices we make during the data warehouse design phase can make or break our SSAS cubes. You may remember that I did this session a while back for Pragmatic Works via webinar. I’ll be doing the same session at SQL Saturday Orlando but on-prem! ;)

So get signed up for this event now! It’s only 11 days away!

Create Date Dimension with Fiscal and Time

Here are three scripts that create and Date and Time Dimension and can add the fiscal columns too. First run the Dim Date script first to create the DimDate table. Make sure you change the start date and end date on the script to your preference. Then run the add Fiscal Dates scripts to add the fiscal columns. Make sure you alter the Fiscal script to set the date offset amount. The comments in the script will help you with this.

This zip file contains three SQL scripts.

Create Dim Date

Create Dim Time

Add Fiscal Dates

These will create a Date Dimension table and allow you to run the add fiscal script to add the fiscal columns if you desire. The Create Dim Time will create a time dimension with every second of the day for those that need actual time analysis of your data.

Make sure you set the start date and end date in the create dim date script. Set the dateoffset in the fiscal script.

MDX Puzzle #1

MDX Puzzle #1

Recently, I embarked on a mission to become proficient at writing MDX queries.  This is a challenge, as many of you may already know.  MDX, though a query language, is very different from T-SQL as I quickly found out.  Each week I will share with you a puzzle and then a couple of days later I will share my solution.   Please don’t post your solutions on this blog post.  Only post them on the Solution post, which will contain Solution in the title. Each solution post will contain a section on terminology and concepts if any new ones are introduced and the MDX query that is the solution to the puzzle.  In this first posting there will be a few.  The puzzles will start out very basic, but will move to more advanced MDX techniques as time progresses and my skills improve.  I will be using the Adventure Works 2008 R2 cube, which can be downloaded from codeplex.  So, let’s get started.

My first puzzle was to write what I thought was a very simple query.  Here is the puzzle:

Show:  Product Internet Sales and Order Quantity Measures
Rows:  Product Categories and SubCategories
Columns:  Ship Years
Filter:  Only Show Men from Customer Dimension and Exclude NULL values

Hint:  You will need a tuple for year and measures and for the rows.

Remember, don’t post you solutions here.  Save them for my solution post.  I will post it along with the steps that was taken to solve the puzzle in a couple of days.   Here is a screen shot of what the results should look like:


Don’t forget to check back in a couple days for the solution.

Talk to you soon,
