Hello I’d Like to Change my Mother’s Name

An image showing an imaginary signature showing a changing maiden-name; a theoretical impossibilityA few months ago, our client had a ‘Compliance’ team visit. It was a nightmare. Worse than the general guff Marketing / Sales Departments come up with… or those nasty little changes that are all designed to improve the user experience (you know the ones; where you have to turn some design or code on its head, just because the users are apparently totally unable to understand ‘X’ or ‘Y’*). Anyway, I’m not exactly sure what we were meant to be complying to, but some of the changes were so arbitrary that we could not think of a single justification for them.

Big Release Week

A shopping list tells us what we have yet to buy

A very personal note this time. Last week I released a project that was pretty-much the largest single release that I’ve worked on for my current employer.

Our AddressType table may look like this:

AddressTypeId    Name
1                Home
2                Work

My DB Table / Column Naming Conventions

I recently got around to researching a topic on the internet that had intrigued me, that being the question: “Should Table Names be in the singular, or plural?” For example, should you call a table Employee… or Employees? For as long as I can remember, my impression has always veered towards the singular. I don’t believe this is because I am a programmer, concentrating on row-based operations rather than set-based (because, as much as anything else, I actually started learning SQL with Oracle as pure SQL… not in the context of learning it with a third-generation programming language).
