data management Data management comprises all disciplines related to handling data as a valuable resource. Concept The concept of data management arose in the 1980s as technology moved from sequential processing (first punched cards, then magnetic tape) to r ...

, the time scale of the data determines how it is processed and stored. Dynamic data or transactional data is information that is periodically updated, meaning it changes asynchronously over time as new information becomes available. Data that is not dynamic is considered either static (unchanging) or persistent, which is data that is infrequently accessed and not likely to be modified. Dynamic data is also different from

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. The current version of the wiring schematic is considered dynamic or changeable. These two different contexts for "dynamic" are similar, but differ their time scale. Dynamic data can become static. Persistent data is or is likely to be in the context of the execution of a program. Static data is in the context of the business historical data, regardless of any one application or program. The "dynamic" data is the new/updated/revised/deleted data in both cases, but again over different time horizons. Your paycheck stub is dynamic data for 1 week, or 1 day, then it becomes read-only and read-rarely, which would be ''either and both'' static and persistent.
