Title Meta-Data management based on big data platform
Abstract
Today, the establishment of efficient data warehouse determines the companies to store and
manage vast amounts of data and the quality of their data, and data quality attributes and in
which played a crucial role, which allows businesses and companies gradually realized metadata
as well as metadata management and its practical significance in enterprise data management
applications.
The big problem in Jiangsu Tianyi Electric Co., Ltd. power collection system data warehouse
project as an opportunity to practice from the enterprise data warehouse and big data platform,
and in the study of metadata and metadata attributes and In practice, seeking an efficient and
high visibility of metadata management.
This paper describes the status of development of big data, and describes the benefits of
electricity Mandarin day gathering background and platform design of large data platform.
Thereafter, the paper also discusses the relevant knowledge of metadata. In addition, the article
focuses on the basics of important metadata management applications in enterprise development,
that is the data dictionary, data analysis and data lineage feature. On the basis of the above three,
focusing on the two based on their technical - data retrieval and data maps, and combined with
its specific application in the enterprise development, it introduces the electricity collecting
primary data for this stage of mainstream technology platform application and the reasons
therefor.
Finally, the big day benefit the establishment of Jiangsu Power Technology Co., Ltd. electric
acquisition system based on primary data platform, combined with the previously mentioned big
data platform and metadata management basic knowledge and engineering application, the more
detailed description of the main data platform theoretical foundation, design ideas and
construction processes.
