Data warehousing infrastructure for web based reporting tool

The present invention relates generally to information delivery systems and, particularly, to a novel, World Wide Web/Internet-based, telecommunications network data management reporting and presentation service for customers of telecommunications service entities. A data warehousing infrastructure for telecommunications priced call detail data is integrated with a Web/Internet based reporting system providing a common GUI enabling the requesting, customizing, scheduling and viewing of various types of priced call detail data reports. Such an infrastructure performs an extraction process to obtain only those billing detail records of entitled customers, and a harvesting process for transforming the billing records into a star schema format for storage in one or more operational data storage devices. The system is integrated with a database server supporting expedient and accurate access to the customer's telecommunications priced call detail data for priced call detail data report generation.
