摘要： 针对多维表达式(MDX)的非结构化对增量操作的限制，提出了一个对象化的查询结构，并阐述了在该结构的基础上对分析路径的跟踪和序列化的实现。该对象结构可以使OLAP 系统高效方便地实现对分析线索的维护和对分析动作的记录，提高了OLAP 系统的可用性。

Abstract: According to the restriction of incremental operation based on the non-structure of multidimensional expressions (MDX), this paper introduces an object-oriented query structure, and describes the realization of tracing and serialization of analysis routes on the basis of this structure. This object structure can allow an OLAP system to maintain the analysis clues and to record the analysis actions effectively and conveniently, which improves the usability of the OLAP system.
