Age calculations – Just how old ARE you?

Any database application that stores information about people will very likely store a person’s date of birth as part of that data. Whether it be for marketing purposes, or part of the security checks for a password reset, or part of the authentication when the inevitable call centre calls you with their “latest, greatest offer”, the date of birth is common.

But when it comes to reporting, typically it is not the date of birth that we present on our screen or hard-copy, but the person’s age. Clearly we cannot store a persons age in the database because it changes every day, month or year depending on the granularity with which you present it. Which leads to the ponderance – Surely it cannot be that hard to calculate someone’s age from their date of birth?

Happy Birthday to oracle-base.com (sort-of)

birthday-cake-clipartToday is another anniversary, but this time it’s the website, which is 15 years old.

OK. This is a bit of a cheat because:

  • The website originally had a different name, so you could say the website with it’s current name is 13 months younger, but it’s the same site, so whatever.
  • I don’t actually know the exact day the first page went online, but I do know the date I bought the original domain name (before the rename to oracle-base.com), so I know the first page was put up about now.

Anyway, July 3rd is from now on the official birthday of the website. Makes it easy to remember, because it’s the day after my birthday.

Cheers

Happy Birthday to Me!

Happy Birthday, OFA Standard

Yesterday I finally posted to the Method R website some of the papers I wrote while I was at Oracle Corporation (1989–1999). You can now find these papers where I am.

When I was uploading my OFA Standard paper, I noticed that today—24 September 2009—is the fourteenth birthday of its publication date. So, even though the original OFA paper was around for a few years before 1995, please join me in celebrating the birthday of the final version of the official OFA Standard document.
