ABSTRACT:
A data management method and system for classifying shared data as new data or past data where the new data may be updated by processing and the past data may not be updated by processing. The data management method and system has a concurrency control, a central control and a sharing of data by a plurality of users wherein the past data is no subject to updating hereby precluding the need for lock processing by concurrency control of past data. In addition, together with query language, the capability of processing new and past data separately allows for an increase of concurrency control efficiency and a smoother user operation.
