Time-Constrained Transaction Management: Real-Time Constraints in Database Transaction Systems (Advances in Database Systems)
TimeConstrained Transaction Management RealTime Constraints in Database Transaction Systems - Advances in Database Systems Author:Nandit R. Soparkar, Henry F. Korth, Abraham Silberschatz Transaction processing is an established technique for the concurrent and fault-tolerant access of persistent data. While this technique has been successful in standard database systems, factors such as time-critical applications, emerging technologies, and a re-examination of existing systems suggest that the performance, functionality and... more » applicability of transactions may be substantially enhanced if temporal considerations are taken into account. That is, transactions should not only execute in a `legal' (i.e. logically correct) manner, but they should meet certain constraints with regard to their invocation and completion times. Typically, these logical and temporal constraints are application-dependent. This book addresses some fundamental issues for the management of transactions in the presence of such constraints. Time-Constrained Transaction Management discusses issues regarding timing estimates, the software and hardware architectures, and the target applications; in detail, for some instances. While the research described in this book is based on a specific model, the results may be generalized to others. Therefore, the issues raised, and the techniques developed, represent several fundamental considerations in the management of time-constrained transactions. Time-Constrained Transaction Management provides the basis for new directions in research in diverse areas such as database technology, distributed systems, real-time systems, fault tolerant systems, and scheduling theory.« less
