Method for mapping call detail data into a database for quick retrieval, Tue Aug 24 18:10:01 EDT 2004

The present invention relates to fast data retrieval. The present invention discloses storing call detail data into two databases. A portion of the total call detail data available is mapped into an interpreted usage event (IUE) and stored in a first database that is indexed for quick data retrieval utilizing a standard database management system. The total raw call detail data is stored in a second database that is less structured, with respect to the first database, without requiring explicit indices. IUEs are retrieved from the first database in response to queries specifying one or more of the characteristics of the desired IUEs. Call detail data stored in the second database is retrieved in response to queries specifying the characteristics from one or more of the retrieved IUEs.

Database Management System With A Multiple-Level Cache Arrangement, Tue Jul 22 18:08:47 EDT 2003

A data management system for storing data in a multiple-level cache arrangement of a database comprises a multi-tier cache memory for initially storing all data in summary form in a secondary cache which may be the database; a processor for receiving requests for data and for moving requested data from the secondary cache to a primary cache, wherein, when subsequent requests for data are received, the primary cache is searched before the secondary cache; and for periodically synchronizing and merging all data in the primary cache back into said secondary cache to refresh said primary cache and remove stale information. The system is particularly useful for managing a telecommunications system call detail summary database in which telephone call details are collected as AMA records after the calls terminate and the AMA records are forwarded to a call detail database for storage in summary form and analysis by an external system, for example, for fraud analysis or billing purposes.
