Part of the Computing fundamentals glossary:

Based on our inferences about the only three uses of this term that we have discovered on the Internet, indempotency (pronounced ihn-dehm-POH-tuhns-ee , from Latin indemnis or "unharmed") is the ability to preserve the integrity of a thing or action no matter how much it is used or accessed by another thing or action. For example, in computer programming, it would usually be desirable for a table that was updated by different sources to reflect the same updated information whether that information was sent in once or many times. A method that ensured such integrity could be said to provide indempotency.
