摘要：Disclosed is a mechanism, system, interface, and process to determine one or more life intervals when given a key. In addition, one or more life intervals can be determined for each key within a range of keys. This type of process is useful for auditing purposes or if it is desire to implement a query upon past versions when a key or range of keys is specified for the data for which past versions is desired. This facilitates algorithms, mechanisms, and processes to implement a query upon past versions.
