Abstract
A relational database method and apparatus includes a database that is divided into multiple data segments, each of which may be independently stored on one of a variety of storage devices. As data from the relational database is being loaded, the number of data segments will increase. A range index is used as a high level filter to determine which indices and data segments will be used to process a query of the database.
