A Meta-Data Management System for Data Warehouse

A data warehouse is simply a single, complete, and consistent store of data obtain from a variety of sources and made available to end users in a way they can understand and use in a business context. To manage and maintain the heterogeneous data source and huge amount data of a data warehouse, much research has been done in the topic called Meta-Data management system. Current research for Meta-Data management systems is focused on the management of the heterogeneous database schema but not system performance. This paper describes a new Meta-Data management system architecture, which is focused on the uniform Meta-Data model and the query performance. The new system includes a repository to store an integrated database schema which is constructed from the different source database schema and a proxy database server which is to store used data by following the structure of the integrated database schema. This new architecture can increase the query performance and reduce the loading to manage the huge amount data for a data warehouse.
