Method for mapping call detail data into a database for quick retrieval

摘要

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.
