Abstract

A transactional system serves subscribers in a plurality of localities, and includes a national data base having a plurality of groups of addressed segments of data storage. Each group stores data pertaining to an associated locality, and each group is addressed by a locality number. There are provided a plurality of access-number addressed segments of data storage, and a device for linking the access-number addressed segments of data storage to the groups of locality-number addressed segments of data storage. At least one locality includes a plurality of sublocalities, and each locality number has a predetermined number of digits signifying the respective locality, and at least one additional digit for identifying the sub-locality; the latter may identify the zip code number. The groups of addressed segments of data storage preferably include classified ad sections. The linking device includes an apparatus for retrieving the subscriber zip code from the zip code addressed segments of data storage, a device for counting the number of ads in addressed segments of data storage, and a device for transmitting to a subscriber controlled data access unit the counted ads. The subscriber controlled data access unit includes a plurality of subscriber units, each having a locality number corresponding to its geographic location. Each subscriber has an access number, a device for transmitting the access number to the national data base, a display for displaying locality data, and a device for the national data base to receive and process the access-numbers.

Dependent claims

A transactional system serving subscribers in a plurality of localities, comprising a national data base having

a plurality of groups of addressed segments of data storage, each group storing data pertaining to an associated one of said localities, each group being addressable by a locality number,
a plurality of access-number addressed segments of data storage, each assigned to one of said subscribers and storing a locality number for said one of said subscribers,
means for linking said access-number addressed segments of data storage to said groups of locality number addressed segments of data storage, so that locality data stored in the group of locality number addressed segments of data storage associated with a subscriber's locality number is automatically addressed upon receipt of said subscriber's access number,
wherein at least one of said localities comprises a plurality of sub-localities,
wherein each of said locality numbers has a predetermined number of digits signifying said localities, and at least one additional digit for identifying respective sub-localities,
wherein said locality numbers are zip code numbers,
wherein said groups of addressed segments of data storage comprise classified ad sections, each having a respective number of ads stored therein,
wherein said linking means comprises
means for retrieving a subscriber zip code from said access number addressed segments of data storage in response to entry of said subscriber's access number,
means for addressing groups of data storage segments using the retrieved zip code number and for counting the number of ads in any locality number addressed segments of data storage corresponding to localities having the same first 3 digits as said retrieved zip code, and
means for transmitting to a subscriber controlled data access means the so counted ads, if said number of ads is less than a predetermined maximum ad number, or transmitting only sub-locality ads in locality number addressed segments of data storage having zip codes having the same first 4 digits as said retrieved zip code, if the so counted number of ads exceeds said predetermined maximum number;
and
said subscriber-controlled data access means comprising a plurality of subscriber units, each having a locality number corresponding to a geographic location thereof, each subscriber having an access number,
means for transmitting said access number to said national data base,
display means for displaying locality data received from said national data base, and
means for said national data base to receive and process said access-numbers.

a national data base having
a plurality of groups of addressed segments of data storage, each group storing data pertaining to an associated one of said localities, each group being addressable by a locality number,
a plurality of access-number addressed segments of data storage, each assigned to one of said subscribers and storing a locality number for said one of said subscribers,
means for linking said access-number addressed segments of data storage to said groups of locality number addressed segments of data storage, so that locality data stored in the group of locality number addressed segments of data storage associated with a subscriber's locality number is automatically addressed upon receipt of said subscriber's access number,
wherein said national data base is accessible by non-subscribers and comprises
access code generating means including a random number generator for generating an access-number for any non-subscriber who attempts to access said data base, and
means for storing the so generated access-number in one of said access number-addressed segments of data storage,
wherein said non-subscriber further furnishes his home address to said national data base,
wherein said access number is mailed to said non-subscriber at said home address, whereby said non-subscriber becomes a subscriber;
said transactional system further comprising
subscriber-controlled data access means, including a plurality of subscriber units, each having a locality number corresponding to a geographic location thereof, each subscriber having an access number,
means for transmitting said access number to said national data base,
means for transmitting data to said subscriber-controlled data access means,
display means for displaying locality data received from said national data base, and
means for said national data base to receive and process said access-numbers.

A transactional system serving subscribers in a plurality of localities, comprising

a national data base having
a plurality of groups of addressed segments of data storage, each group storing data pertaining to an associated one of said localities, each group being addressable by a locality number,
a plurality of access-number addressed segments of data storage, each assigned to one of said subscribers and storing a locality number for said one of said subscribers,
means for linking said access-number addressed segments of data storage to said groups of locality number addressed segments of data storage, so that locality data stored in the group of locality number addressed segments of data storage associated with a subscriber's locality number is automatically addressed upon receipt of said subscriber's access number,
subscriber controlled data access means having a plurality of subscriber units each having a locality number corresponding to its geographic location,
each subscriber having an access-number, wherein said data access means comprises means for transmitting said access-number to said national data base, and display means for displaying locality data received from said national data base,
a predetermined number of telephone lines linking said subscriber controlled data access means to said national data base,
wherein said national data base further comprises means for answering subscriber calls, means for assigning a process identification number to each received call, means for comparing the number of process identification numbers to said predetermined number of telephone lines, and means for commencing timing of said calls when said number of process identification numbers is equal to said predetermined number of telephone lines,
wherein said transactional system further comprises revenue-producing transactions and non-revenue transactions, and
wherein said means for commencing timing of said calls delays timing of said revenue-producing transactions relative to timing of said non-revenue producing transactions;
and
means for transmitting data to said subscriber controlled access means, and
means for said national data base to receive and process said access-numbers.
