摘要
A computing system associates time series data with data base changes, received from concurrent processes, that are recorded in an activity log by defining a data base table to include a column in which a system clock time stamp value can be recorded when initializing a new copy of the data. Initialization can be set to occur automatically at periodic intervals or whenever a fresh copy of a set of data records is requested by a system process. The writing of the time stamp data associates a time value with the copy initialization activity and makes time series data available to processes that otherwise would have no time knowledge. The prior user-defined data base does not have to be modified to utilize the time stamp feature because a new, system-defined table is used.
