| 摘 要： | 在数据仓库系统DB-ODS-DW三层体系结构中,ODS具有承上启下的重要作用。传统的ODS对元数据的管理没有一个统一的平台,致使元数据管理成本较高,并难于维护。提出了一种针对于ODS的元数据管理的元数据仓技术,该方法使ODS元数据的管理更加规范化,且与元数据存储库相比具有复杂度小,成本低的优点。在此基础上,提出了一种基于元数据仓的ODS创建模型。

| Abstract: | In the 3-level architecture DB-ODS-DW of data warehouse system,ODS takes a connecting link functions between the preceding and the following program.There is not a uniform plat to manage metadata in the traditional ODS,so the metadata managing cost is much higher and difficult to maintain.A metastore technology of ODS metadata management is proposed in the paper which can make ODS metadata management much standard,and has lower complexity and cost compared with metadata repository.An ODS construction model based on metastore is put forward finally. |
