That index (e.g., 437) can later be used to search for and retrieve the record (and only that record).

#SEQUENTIAL NUMBERS MEANING SOFTWARE#

If software counts data records (or pigs) sequentially with whole numbers, then it can guarantee that each data record has a unique index. Sequential numbers occur in software because of the assumption above, but also because counting sequentially maintains the uniqueness of each number. That assumption, however, can have disastrous consequences for a client's software, particularly when trying to avoid 'screen scraping' – where an application visits a website to copy its contents – and the best design decision is often to avoid sequential numbers at all costs.

4 existed is because we are biased to believe that numbers occur sequentially without gaps. 4 lumbering around campus, searching for a loose Dunkin' Donut or a revolution to start.Īnd the reason people would assume Pig No. (There was also no pool on the roof of the school.) All that said, the story is a fun one because people would assume that there was a Pig No. This legend is almost definitely not true: 1) There are not many pigs in or around my Massachusetts hometown that strictly regulates livestock 2) The story was sometimes told with lobsters, which while there are more lobsters in Massachusetts, makes even less sense (how do you paint a number on a lobster?) and 3) The story was told to me by a 14-year-old. The joke was that the school would spend all day searching for Pig No. Each pig was painted with a number: 1, 2, 3 and 5. There was a legend that one class in the 1970s had released four pigs in the hallways. The class above us released crickets in the lunchroom another class set up chicken pens (with chickens) in the courtyard.

When I was in high school, the seniors would pull a prank in the late spring after college acceptance letters came in.
