Recently, I have been writing an internal jargon buster for data engineering terms and concepts. I was writing a definition for Normal Forms, when I realised I would also need a definition for keys. But how best to explain all the different types of database keys?
This has been an intermission and a half. Since I was last posting regularly, I have become a permanent consultant, and then become a consulting lead. But in truth, my intermission was not caused by being busy - at least, that wasn't the significant turn of the needle.
