【Abstract】 This paper discusses that in the real time database systems, the values of data with time constraints will be changed by the time passing by. The committing protocol of real time transactions, which processing these data with time constraints has also been proposed. And by analyzing whether the data has time constraints, a concurrency control model is addressed.更多还原
