A Real-Time Concurrency Control Protocol for Main-Memory Database Systems
Protocols developed so far for concurrency control in real-time database systems have assumed a dynamic acquisition of data resources as it is impossible to predict which instances of relations will actually be accessed by each transaction. In this papert, we present a new concurrency control protocol for main-memory real-time database systems, which is baaed on predeclaration of data requireme...
متن کاملAn Optimistic Concurrency Control Protocol for Real-Time Database Systems
Transactions in real-time database systems are associated with certain timing constraints derived either from temporal consistency requirements of data or from requirements imposed on system reaction time. Fundamental requirements of real-time database systems are timeliness, i.e., the ability to produce expected transaction results early or at the right time, and predictability, i.e., the abil...
متن کاملConcurrency Control in Real-Time Database Systems
Real-time systems (RTSs) form an important class of computer systems. They are characterized by existence of timing requirements concerning task execution times, and processing data items which values and validity change in time. We observe the growing importance of RTS applications which is accompanied with both the increase of data volumes processed by the systems and the requirements concern...
متن کاملConcurrency in Main-Memory Database Systems
The availability of powerful servers with terabytes of main-memory has sparked a renewed interest in main-memory database systems. Many early proposals focus on a single workload type, either short transactions or long-running, read-only analytical queries. In this thesis, we focus on allowing a broad range of workloads to be executed concurrently on the same state of the data. While concurrenc...
متن کاملA Simplified Concurrency Control Algorithm For Real Time DataBase Systems
Real Time Data Base Systems must insure temporal consistency as well as logical data consistency to exhibit correct behavior. The performance of these systems is measured as a percentage of transactions executed into their temporal restrictions. To achieve a good performance, Real Time Scheduling algorithms are needed. In this work a Real Time Scheduling algorithm based on a combination of both...
