Implementation of transactions scheduling for real-time database management

The results of transactions processing in realtime database must to satisfy the temporal constraints associated to both transactions and data, besides maintaining the logical consistency imposed to them. In order to solve this problem, we present the implementation of real-time transactions scheduling considering semantic concurrency control technique. As results, the best execution sequence of the transactions operations must be produced, where the transactions maximum amount attends its deadlines using valid data. This paper describes the schedule implementation using threads class in java.
