Efficient update methods for large volume data updates in data warehouses

Image Number 2 for United States Patent #8055609.

A system and method for ensuring large and frequent updates to a data warehouse. The process leverages a set of temporary staging tables to track the updates. A set of intermediate steps are performed to accomplish bulk deletions of the outdated changed records, and perform modifications to the map tables for models such as snowflake. Finally, bulk load operations load the updates and insert them into the final dimension tables. The process ensures performance comparable to insertion-only schemes with at most only slight performance degradation. Furthermore, a modified process is applied on the newfact data warehouse dimension model. The process can be readily adapted to handle star schema and other hierarchical data warehouse models.
