    • A system maps a multidimensional model to data warehouse schema. The system includes a multidimensional model editor for defining a multidimensional model based on a conceptual model; a mapping reasoner for generating more simple mappings from basic mappings by reasoning on the conceptual model so as to provide mappings for concerning elements in an ontology path in the multidimensional model; a data warehouse schema analyzer for generating a data structure capable of indicating information of the data warehouse schema by making an analysis on the information of the data warehouse schema; and a mapping composition engine for generating result mappings according to mappings for the concerning elements of the ontology path in the multidimensional model and by searching in the data structure paths corresponding to the concerning elements of the ontology path in the multidimensional model. A method and computer program product are also disclosed.
    • 系统将多维模型映射到数据仓库模式。 该系统包括用于基于概念模型定义多维模型的多维模型编辑器; 一种映射推理器,用于通过推理概念模型从基本映射生成更简单的映射,以便为多维模型中的本体路径中的元素提供映射; 数据仓库模式分析器,用于通过对数据仓库模式的信息进行分析来生成能够指示数据仓库模式信息的数据结构; 以及映射构图引擎,用于根据多维模型中的本体路径的相关元素的映射生成结果映射,并且通过在与多维模型中的本体路径的有关元素相对应的数据结构路径中进行搜索来生成结果映射。 还公开了一种方法和计算机程序产品。
