A distributed database system includes a central station for accumulating and distributing data on a database, and a plurality of receiver stations that receive the data and selectively make available at least portions of the data in accordance with the demands of a user. A transmitter encodes and transmits the sequential data stream for delivery embedded within television signals.

A method, system and program for displaying database information via a table containing icons and other summary information which clearly and concisely convey particular aspects of a database to a user. The table display acts as a window into a database when it is selected by a user. A user can also make changes to the database via the window of information.

A physical database designer which is embodied in computer software that generates a physical database design. The designer follows a process which includes the steps of (a) entering a logical schema representing the database to be designed; (b) entering a hierarchial definition of the workload experienced by the database, which includes, for each level of a hierarchy of operations, a separate specification of workload; and (c) applying expert rules to the logical schema and the workload definit...

A Process for analyzing full-text is provided for identifying often-repea, high user interest, word phrases in a database. Often-repeated, high user interest, word phrases are defined as pervasive theme areas (PTAs). The process also allows the relationship defined as connectivity among the various PTAs to be identified. In addition, phrases that are in proximity to the PTAs and which are strongly supportive of the PTAs are identified. Numerical indices, figure of merit, and user defined thresho...

Interexchange carriers make their rate information for long-distance service available in a database. PBXs and telephone central offices access that rate information using ISDN and/or SS7 signaling and use it as a basis for determining which carder to use at any given time in the routing of a call. Such accessing may be carried out on a call-by-call basis. Or a carrier's schedule of rates can be stored locally in the PBX or local switching office, thereby obviating the need for a database query ...

A method, system and program for efficiently archiving and recovering a database is disclosed. The archiving process utilizes a reverse chronological order for the tape to facilitate efficient restoration of the database. The recovery processing utilizes a linked list to track record updates and avoid updating the same record with anything but the most current information.

A method of performing update transactions in a database system to perserve consistent logical data states at all times. Each changeable data entry in the database is associated with an individual code field. When no update transaction is in progress, every code field is set to a first value. An update transaction is begun by changing a system state parameter from a NON-UPDATE to an UPDATE state. During the UPDATE state, the code fields of data entries to be added are marked with a second value ...

A system is provided for duplication of an update database in a computer using partial data extraction. A copying module creates a copy database, including a partial copy, of the update database. A journal selecting module selects data, related to parts of the copy database in which the copy has finished, from an update data journal of the update database that is made when the copy database is being copied by the copying module. A duplication module updates the contents of the copy database crea...

A method for broadcasting data to a television set using a carrier signal such as a television or commercial radio carrier signal composed of the steps of: constructing a data stream from individual first record of a transmission database, each first record comprising one of a selection of formats, at least one of the first records comprising executable program code or an object, broadcasting the data stream within the carrier signal, providing a user with a user's device for receiving and decod...

A push type information providing service on the Internet. When information arranged on a time axis and retrieved is output time to time, the information is output/displayed in sequence on the time axis along a scenario described with position information of a plurality of data stored in databases distributed on the network. In displaying the position information of the data, secondary information such as advertisement, etc., is inserted onto the time axis of the position information of the retr...
