The First Rule of Software Development

There are many rules that could claim to be the “first rule”…..

 How about:

 “Never have the same data maintained in two different places.”

 If you don’t follow this rule you immediately have a new task of ensuring that the two different places contain the same data and also the headache of what happens when they do contain different data.

 It sounds obvious, but you’d be amazed how many times this rule is violated.
