| 摘 要： | 为改善分布式主动实时数据库事务处理的可预测性，提出了一种新的基于树的事务语义模型，并基于该模型提出了一个分布式主动实时事务预分析处理与动态预测的集成框架，包括事务生成时的静态预分析、事务接纳时的初始动态预分析和事务运行阶段的即席分析与预测，它可以有效地支持分布式主动实时事务的静动结合分析，改善事务处理的实时性能．

| Abstract: | In order to improve the predictability of distributed active real time transaction processing, a tree like semantic model of distributed active real time transaction was proposed. Based on this model, an integrated framework of preanalysis processing and prediction for distributed active real time database transactions was presented. This frame consists of the static transaction preanalysis in the application development, the initial dynamic preanalysis at admission of transactions and the dynamic analysis prediction during their execution. It can support conjoint static and dynamic analysis for distributed active real time transactions, and enhance the real time performance of transaction processing. |

| Keywords: | distributed real-time database active database real-time transaction transaction preanalysis dynamic prediction |
