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

We’ve completed reviewing the major Microsoft tools and now you have to make “The Decision”. Which tool(s) is the best fit for the reporting needs? Remember just picking one tool and using it for all reports may not be the best decision because you are missing out on a lot of the benefits of other tools.
One tool I like to use that helps me make a decision like this is a decision matrix. With a decision matrix you provide the possible options, which for us has been the following tools:
You also provide the factors that are important to you in making a decision. You can see in the screenshot below I’m considering tools based on:
Within the matrix you rate each of the tools (0-100) in their capabilities of the factors you’re considering. This rating should only be done once.
Some factors to making a reporting decision may be more important than others depending on the need. For example, for one report Ad Hoc Reporting may be the most important thing while another report Content Sharing may be the most important thing. That’s why you sign a relative weight (0-10) to each decision you need to make. That way if Ad Hoc Reporting is most important than rate it higher than the other factors. Again, this weighting system would be changed for each report you need to make a decision on choosing a tool.

Using a tool like a Decision Matrix can help you make decisions quickly and with more confidence. I hope this series has been helpful. If you need to catch up on previous posts follow the links below.
