摘要
主动数据库的简单规则形式不符合主动数据仓库(ADW)的决策特点,而基于ADW的分析规则在交互性、精确性、表达能力和扩展性等方面存在不足。根据ADW规则渐进分析分布决策的特点,结合ECA规则形式,定义了一种主动多维分析规则模型及相应语法(AMAR)作为ADW规则的表述和执行方式。AMAR不仅可以应对ADW规则的诸多挑战,还提供了对立方体、事件、规则、结果之间复杂对应关系的支持,同时具备了更好的可维护性和可执行性。
The simple ECA rules for active database does not comply with the requirements of active data warehouse （ADW） decision making characteristics, analysis rules based on ADW has some deficiencies in the areas of interactive, accuracy, scalability and expression ability. According to the gradual analysis characteristics of ADW rule and the ECA forms, an active multi-dimensional rule model and its corresponding grammar AMAR is put forward. AMAR can not only deal with the numerous challenges of ADW, but also provide the support for the complex corresponding relationship between the cube, event, rule and result. Additionally, the better maintainability and performability is realized.
