Introducing: Dirty Master Data Management Application
This is a side project of mine, something to keep me out of mischief at home. My aim for this project is to be an example/template/starting point for using flask for a quick (and dirty) approach to a Master Data Management (MDM) application AKA a Data Warehouse Management Application (DWMA).
Dates In SQL Server

Partitions in SQL Server: Partitioning a Table on a non Primary Key Column
In my series on partitioning, I’ve looked at creating a fact table partitioned by date. But I recently came across a case where I’d got data which had a date which should be used for the partition, however there was also a natural key in the data which should be maintained as a primary key.…
