Dynamic data

It may also include engineering transactions, such as a revised schematic diagram or architectural document.

In this context static data is either unchanged or so rarely changed that it can be stored remotely ("basement" or far) storage, whereas dynamic data is reused or changed frequently and therefore requires online ("office" or near) storage.

An original copy of a wiring schematic will change from dynamic to static as the new versions make it obsolete.

It is still possible to reuse the original, but in the normal course of business there is rarely a need to access obsoleted data.

Your paycheck stub is dynamic data for 1 week, or 1 day, then it becomes read-only and read-rarely, which would be either or both static and persistent.
