Nightly, the system provides a pre-processing program to each of the servers. The servers executing the pre-processing component to filter the logged data before sending it on to the data collection and warehousing system. The data collection and warehousing system pre-parses each received log file to create dimension and fact tables. During this process, strings are replaced by keys. These keys are calculated on-the-fly by taking a hash of each string. The resulting tables are then further parsed to create further dimension and fact tables that correspond to each of the dimension and fact tables of a relational database schema. After further processing, these tables are loaded into a data warehousing system.
