Usage-based optimization of network traffic and data warehouse size

机译:基于使用情况的网络流量和数据仓库大小优化

摘要

The present invention generally provides systems, methods, and articles of manufacture for maintaining a data warehouse having a plurality of fields updated with data from one or more data sources. Rather than automatically update every field of data available in the warehouse, a limited subset of fields identified through their involvement in queries issued against the warehouse are updated. By limiting the fields that are updated, the network bandwidth required to transmit the updates to the data warehouse may be reduced. Further, by removing fields from the data warehouse that are not in use, the size of the data warehouse may be reduced.
