ABSTRACT:
In a telecommunications network, a method is provided for reading a desired telephone data record associated with a given telephone number from a line record database. Initially, a data processor reads data from an accessing data record stored in an index database. The accessing data record contains at least an accessing number designating a series of telephone numbers including the given telephone number, a pointer pointing to a data cluster in the line record database, and a blocking factor associated with the data cluster. The data cluster comprises a plurality of data nodes and includes all of the telephone data records associated with the series of telephone numbers designated by the accessing number. Each data node contains a number of individual telephone data records up to the blocking factor and a number of pointers each pointing to one of the number of individual telephone data records. The data processor accesses a data cluster based on the data read from the index database. The data processor then determines the position of a desired data node containing the desired telephone data record in the data cluster, the total number of telephone numbers in the data cluster, and the blocking factor. Then the data processor reads the desired data node and extracts the desired telephone data record from the desired data node using the pointer associated with the desired telephone data record.
