摘要
用户在 OL AP系统中的行为往往有一定的规律 .在认定用户的查询意图相对稳定的前提下 ,分析用户的行为能提高 OL AP系统的性能 .而在分析用户的行为之前 ,选择合适的用户查询模型 ,记录用户的行为显得尤为重要 .本文提出一个模型 ,包含了绝大多数的 OL AP系统的操作 .
User's query behavior in an OLAP system often follows some certain patterns. When the intention of a user's query could be considered as steady, the analyzing of user's behavior can help much to improve the performance of an OLAP system. Thus, before the analysis of user's behavior, it is very important to select a proper model in order to record user's query behavior. This article provides a model which contains most operations in common OLAP system. Further more, this model can record user's behaviors rather completely.
