Abstract: Complex query based on data cube is the development direction of cube technique. This paper detects three types of the dependent-relationships in complex data cube query, and proposes three methods based on cache reusing accordingly. The experiments on synthetical and real datasets illustrate the approaches proposed are efficient and promising.

Key words: data cube query, complex query, granular computing

摘要： 基于数字立方体的复杂查询是立方体技术的发展方向。该文针对复杂立方体查询中可能存在的3种聚集依赖，分别给出3种基于Caching重用技术的解决方法。在模拟数据集和真实数据集上的实验结果验证了该方法的有效性和正确性。
