Implementation of transactions scheduling for real-time database management
ABSTRACT 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.

ABSTRACT: More and more databases are being used in situations where realtime constraints exist. A set of misconceptions have arisen regarding what a real-time database is and the appropriateness of using conventional databases in real-time applications. Nine misconceptions are identified and discussed. Various research challenges are enumerated and explained. In total, the paper articulates the special nature of real-time databases. 1 Introduction In 1988 a paper entitled Misconceptions of Real-Time Computing was published . This paper articulated the key differences between general purpose computing and real-time computing. The impact of the paper was significant in that it spurred a lot of research that specifically focussed on real-time issues. We believe that there is now a significant body of scientific and technological results in real-time computing, in part, due to the careful definition of real-time computing and the articulation of the important differences between real-ti...IEEE Computer. 01/1999; 32:29-36.
