摘要
通过对大量决策分析算法的分析,提出了基于限制(Constraint)的OLAM任务语义模型,该模型从一定的逻辑高度对OLAM进行抽象,利用它可以分析OLAM任务的共性,提取OLAM任务执行时的基本操作,这些基本操作的基础是语义片断。文中给出了语义片断之间关联关系的分析和判断方法,提出了基于限制的、具有方向性的语义关联度定义。语义片断间关系的确定是OLAM任务/事务优化的基础。
Through analyzing plenty of decision analytical algorithms, an OLAM semantic task model based on the constraints is presented. The model can be utilized for analyzing the common characteristics of OLAM task and extracting the elementary operations, the basis of which is the semantic slices. The definition of semantic slices based on the constraints and the relationship judging methods of the semantic slices are given. The relationship among the semantic slices is the foundation of optimizing the OLAM transactions.
