Active databases and real-time databases have been important areas of research in the recent past. It has been recognized that many benefits can be gained by integrating real-time and active database technologies. However, not much work has been done in the area of transaction processing in real-time active databases. This paper deals with an important(More)
Data in real-time databases has to be logically and temporally consistent. The latter arises from the need to preserve the temporal validity of data items that reeect the state of the environment that is being controlled by the system. Some of the timing constraints on the transactions that process real-time data come from this need. These constraints, in(More)
1 Introduction A methodical study of real-time database applications can help us identify the important research issues in real-time databases. In 4] a number of real-time database issues are discussed. In this paper, we discuss the data and transaction characteristics of a telephone network services database in an attempt to study real-time database issues(More)
