All data warehouses need a date dimension to enable proper analysis across dates. Most Data Warehouse designers will just use one provided by tools or whip it up in Excel, but what if you need to set up custom holidays or want different calendars, such as Fiscal or Julian? You can have any date dimension you need by using a single SQL script that can be modified and rerun as necessary. Learn what it takes to design a date dimension that does all of the calculations and formatting up-front so the reports can be easier to create. Sample script will be provided that creates the date dimension and can be reused as often as necessary without breaking your data warehouse and it only takes seconds to run!
