Metadate Manage Technology In Business Intelligence System Research And Applications

As science and technology and the development of data warehouse technology, management and access large data sets has become the complexity of data producers and users are facing the outstanding issues, data producers need effective ways to organize, manage and maintain Massive Data. Metadata describes as data content, quality, condition and other characteristics of the role of information has become increasingly important as the effective management of information resources and the application of the important means.This paper business intelligence data heterogeneous systems, users are too many levels, as well as the data cover a wide range of features, done some work mainly includes:1.Business intelligence system designed metadata management system. The system uses Java language development, achieved a platform-independent, using the current popular XML, XSLT, and other technology, currently used in a lot of mature open source software projects. Metadata management system and give full play to the advantage of XML technologies, particularly XML separation.2. Hierarchical structure of metadata model made its own research. Specific studies on the skip and ragged hierarchical structure mixed of metadata and OLAP in the realization.This innovation:1. The main innovation is the combination of some of the current metadata standard specifications, the development achieved its metadata management system.2. Metadata and OLAP achieve a skip and ragged hierarchical structure mixed.
