摘要： 基于数据立方体的静态推理控制方法在联机分析处理(OLAP)系统中的访问有效性不高。为此，提出一种基于数据立方体的动态推理控制方法。该方法以提高OLAP系统访问有效性为目的，实时处理在线查询，分析查询方体的推理威胁，阻止其推理产生，并动态返回可访问方体集。实验结果表明，该方法可提高推理系统的有效性，且与静态推理控制方法有相同的安全性。

Abstract: Aiming at the low effectiveness of the static inference control method based on data cube in the On-line Analytical Processing(OLAP) system, this paper proposes the dynamic inference control method based on data cube to improve the effectiveness and to deal with problems of on-line real-time inquiry. The method analyzes the inference and prevents the occurring of inference threats of queried cuboids. The method can dynamically return an accessible set of cuboids. Experimental result shows the improvement of the effectiveness of the inference system and it has the same security as the static inference control method.
