Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a search result output method for a database system, and more particularly, to a search result information output method for a database composed of information of a plurality of media types. be.

[Conventional technology]

In conventional database systems, the type of media handled by a terminal is fixed, and if the media types of the center database and the terminal differ, it is not possible to output database search results.

[Problem to be solved by the invention]

In the conventional technology, when assuming a database consisting of information composed of a combination of various media such as audio, text, graphics, images, etc., it is necessary to prepare a terminal that matches each media type of the information in the database. Another drawback is that it is not possible to realize an output method that combines information of multiple media types. Furthermore, regarding real estate information, for example, the location, area, price, etc. can be displayed in audio or text, but it is necessary to use graphics for the floor plan, and images for the building exterior and interior conditions, and each type of information can be displayed by phone, facsimile, or image. Transmission equipment is used, but in this case there is no interconnection between these terminals, so they must be operated independently.

An object of the present invention is to use a database consisting of information composed of a combination of multiple types of media without necessarily having to prepare terminals that match all the media types of the information in the database, and to make each terminal independent. The objective is to enable database search results to be output from a center to a terminal without any manual operations.

[Means to solve the problem]

In order to achieve the above object, in the present invention, a database information management table is provided at the center to manage the correspondence between information on a plurality of media constituting the database and the media type of the information, and when the database search results are output, the information is transmitted from the center to the terminal. Notify all media types that correspond to the output information, and the terminal selects the media type to be used from among the media types and instructs the center. At the same time, the terminal switches to the input/output device compatible with the media type, and the center instructs the center. The search result of the selected media type is output to the terminal.

[For production]

When outputting database search results, the center that manages the database searches the database information management table and first notifies the terminal of all media types to be output. The terminal selects the media type to be used from among the media types and instructs the center. The center outputs the search results of the specified media type to the terminal. As a result, the center does not need to be aware of the input/output devices of the terminal at all.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a network configuration in which the present invention is applied to a telephone network. 2 is a database, 3 is a database control unit that controls the database, 4 is a telephone with a PB signal sending function (hereinafter referred to as a telephone), 5 is a personal computer (hereinafter referred to as a personal computer) or a word processor (hereinafter referred to as a word processor), 6 is a Facsimile 7 is a subscriber line that accommodates the terminal in the LS of the telephone network. The center 1 is connected to the TS or LS of the telephone network.

Although FIG. 1 shows a single center as an example, the present invention can be similarly applied to a case where multiple centers are installed.

Furthermore, although Fig. 1 illustrates application to a telephone network, it is equally possible to apply to packet networks, facsimile networks, etc., leased lines, or communication networks in which these networks or leased lines are interconnected. .

FIG. 2 shows an example of the center configuration, in which 11 is an audio information storage section, 12 is a character information storage section, 13 is a graphic information storage section, 14 is an image information storage section, 15 is an audio information control section, 16 is a character information control section, 17 is a graphic information control section, 1

The connection and communication with the terminal via the line 24 are controlled by each transmission/reception control unit 20 to 20 corresponding to the media type.
23, and each control unit 15 to 18 corresponding to the media type takes out the stored information. For example, when receiving a PB double signal from a terminal and transmitting audio, the P
When the B-fold signal PB receiver 19 receives the signal, the audio transmission/reception control section 20 analyzes the signal, and starts the audio information control section 15, the audio information control section 15 receives the audio information stored in the audio information storage section 11. The audio transmission/reception control unit 20 transmits the audio information to the terminal via the communication line 24.

FIG. 3 shows an example of the configuration of a database information management table in the center, where 31 is a search table, 32 is a link table, 33 is voice information, 34 is text information, 3
5 is graphic information, and 36 is image information. When searching a database based on search conditions, the search table 31 is searched using search key information (primary search), and if a match is found, the next link table 32 is searched using the link information.

In the link table 32, the presence or absence of the information entity for each medium to be output to the terminal is displayed as ``1'' or it Oj#, and if it exists, the information for each medium is displayed based on the link information (address). Secondary search for accessing storage units 11 to 14), information 33 for each media as search results
~36 is obtained. The example in FIG. 3 shows that audio information 33, text information 34, and graphic information 35 are obtained as search results because audio, text, and graphic information exist, but image information does not exist.

FIG. 4 is an example of a signal format for instructing the center from the terminal. - The membrane format consists of parameters consisting of numbers "0" to "9", a delimiter "umbrella", and a termination code "#". For example, in the search condition for the real estate department, department "05" is the information search for the real estate department, type "46" is the rental of apartments, Region” 15”O
” is on the JR Chuo Line, floor plan “21” is 2DK, price is “10”
" is 100,000 yen per month, terminal type of output terminal "40" is facsimile terminal, network type "10" is telephone network, terminal number is subscriber number in telephone network, instruction code u I PI is search with different search conditions Request, '2' indicates another information output request with the same search conditions, and '9' indicates end of search.

FIG. 5 shows an example of a signal sequence when a database search result is output from the center to a terminal.

The terminal connects to the center by making a call and dialing using input/output device A such as telephone 4. After that, the terminal follows the voice instruction from the center to input the ID and password, and inputs the ID and password using the PB double signal. do.

The center receives the ID and password from the terminal with the PB receiver 19, and determines whether the ID and password t[ is allowed to access the database.

If refused, the line will be disconnected. If permitted, the center instructs to input search conditions, and the terminal inputs the search conditions, e.g.
When searching for real estate information, search for real estate department, property type,
Input the location, floor plan, price, etc. At the center, the search table 31 is searched based on the search conditions, and when key information matching the conditions is detected, the search target media type is identified from the corresponding link table 32, and each media-specific information storage section 11 to 14 is stored. At the same time as searching, the device is notified of the media type. The terminal inputs the media type to be used among the notified media types, the network type that accommodates the input/output equipment corresponding to the media type, and the number of the input/output equipment. The center calls the designated input/output device, for example, the facsimile 6, establishes a connection, and outputs information corresponding to the media type.

Note that if the specified input/output device is already connected to the center, such as when inputting search conditions from a telephone and listening to the search results audibly on that telephone, there is no need to make a new connection. The sequence of calling and connecting the input/output device for switching the input/output device is omitted.

When information output to the input/output device is completed and other media information exists, the center notifies the terminal of the remaining media types. Thereafter, instructions for input/output devices and information output are repeated in the same way. When all information output is completed, the center notifies the terminal. The terminal determines whether to continue the search or end it.

Each instruction is given to the center. If you wish to continue, repeat the same procedure again from entering the search conditions. In case of termination,
The line is disconnected and all processing is complete.

〔Effect of the invention〕

As explained above, according to the present invention, the center manages database information and the media types of the terminal, and when outputting database search results, the center notifies the terminal of all media types to be output, and the terminal Select the input/output device corresponding to the media type to be used from among the media types and instruct the center, and the center outputs the search results to the terminal to select the input/output device corresponding to the information media type in the database. There is an advantage that search results of information composed of multiple media can be output by selecting and switching input/output devices.
