Abstract
The present invention provides an improved method for managing a toll-free number database within a storage medium. The method provides for extending space for record data within the storage medium. Memory space within the storage medium is allocated into buckets for storing records in accord with record size. A database-index is provided for mapping each record to a bucket. A bucket-index is provided for identifying buckets that may receive new records. If a bucket becomes full or approaches full occupancy, a new bucket is added to the database and the bucket-index is updated accordingly. An occupancy-index may be provided for indicating the amount of available memory in each bucket.
