Web-based concurrency control in distributed real-time database system |
| |
| Abstract: | With the development of the distributed application and real-time system, more and more people pay attention to the studies of the distributed real-time database system. Concurrency control of transactions is the emphasis of such study. The algorithm of concurrency control in the distributed real-time database system is presented by analysis of Web properties, such as totally ordering, predictability, caching and so on. The presented algorithm based on predictability is adaptive, helpfully increasing the possibility of meeting the deadline of transactions. |
