基于多维模型的独立型数据集市数据转换策略研究

Data transformation strategy study of independent data mart on dimensional model

数据转换是ETL的重要组成部分,同时也是数据仓库和数据集市得到高质量数据的前提和保证。首先分析并研究了基于维度模型的数据转换的内容,提出并深入研究了基于维度模型的独立型数据集市多阶段数据转换策略和管道数据转换策略,为基于多维模型的独立型数据集市的数据转换的实现提供技术支持和理论指导。

Data transformation house and data mart in order is one important part of ETL , is to get higher quality data. After the precondition and guarantee of data wareanalyzing the contents of data transformation based on dimensional model, the multistage and pipeline data transformation strategies of independent data mart based on multi -dimensional are proposed, which can provide technical support and academic guidance to the implementation of independent data mart of multidimensional model.
