Making Wide World Importers Bigger

Koen Verbeeck wants bigger fact tables for Wide World Importers:

Microsoft released a new sample database a couple of months back: Wide World Importers. It’s quite great: not every (unnecessary feature) is included but only features you’d actually use, lots of sample scripts are provided and – most importantly – you can generate data until the current date. One small drawback: it’s quite tiny. Especially the data warehouse is really small. The biggest table, Fact.Order, has about 266,000 rows and uses around 280MB on disk. Your numbers may vary, because I have generated data until the current date (12th of August 2016) and I generated data with more random samples per day. So most likely, other versions of WideWorldImportersDW might be even smaller. That’s right. Even smaller.

260 thousand rows is nothing for a fact table.  I was hoping that the data generator would allow for a bigger range of results, from “I only want a few thousand records” like it does up to “I need a reason to buy a new hard drive.”  Koen helps out by giving us a script to expand the primary fact table.
