| 摘要 |
The present invention is a data warehouse portal for providing a client with an overall view of one or more data warehouses to aid in the analysis of data in the warehouse(s). The portal allows the client to gain an insight about the data to determine how the data is used, who uses the data, if additional data sources are required, and what impact a data change may have. The portal reads and/or searches metadata and/or XML schemas from the data warehouses and tools available for accessing data stored in the data warehouse, and display the data warehouse information through a browser in numerous ways, such as hierarchical, user and application views. Other views may include extraction, usage, historical and comparison.
