Abstract
Presented is a unified, systematic view of integrity/recovery as it relates to a data-processing system—whether man, machine, or both.
The concept, sphere of control (SOC), as a bound around a process, is developed to permit describing and solving many of the rather aggravating problems of auditability, repeatability, reproducibility, scheduling, consistency, recovery and general integrity.
Identified are the relationships among resources and SOCs, the types of resource status which must be maintained, and the effects that dependency versus commitment has on process scheduling and recovery strategy.
Virtually ignored are the problems of lost storage for which redundancy is a solution, mainly because information already exists in this realm.
