The database management module of the electronic phone book system according to the present invention is based on the subscriber database and daily variation data design of the new 114 number guidance system currently in operation. It manages the overall affairs of the database such as online transmission of the daily change data generated from the module, change of the subscriber's file by these change data, and creation of a new number guide file for the subscriber whose telephone number has been changed.

Now, the electronic phonebook database configuration for this purpose is described. The electronic phonebook database has a large amount of information related to the phonebook, so that it can be quickly retrieved and processed. CISAM (Clndexed Sequential Accexx Method) based on tree method is applied to create and manage index files to efficiently process data processing.

The electronic phone book database adopts the CISAM technique selected as a standard of ATT's UNIX SYSTSEM V, because it has characteristics of telephone number related information as follows. ) And the phone book are divided into five special databases for service.

As an example, the electronic phone book manages a large amount of data records of 3.5 million people and 500,000 subscribers in the Seoul area. However, by retrieving information by the B-tree technique, it ensures a fast retrieval speed of the electronic phone book system. In addition, it is not necessary to overload screen design, reports, and menu processing functions according to the information retrieval results.

Referring to the record structure of the electronic phone book database, the characteristics of the records constituting the file are as follows.

Variable length field structure using a delimiter

Fixed length record structure, no external fragmentaion

KSC5601 2-byte complete Korean code and capitalized English canonical form

Index file: holds information about the configured key value and its position on the reference file

Reference file: holds information on the location of the corresponding record with the configured key

Data file: Holds the actual data record.

The method to search the record by key is as follows.

The value of the entire key

Partial key value without trailing part of the configured key value

Partial field values of the configuration field when searching for records of composite key values

Now, looking at the electronic phone book database construction, the database as described above can be largely divided into two, one is a subscriber database (DB) containing information about each subscriber, the name of the life and industry There is a new number guide, called a special database (DB), a station number, and a domestic local file. These files are transferred from the 114 Information Computer System (KDAS) and converted into a format suitable for the characteristics of the electronic phonebook file structure to construct each file.In the case of an industry group, the Industry Code of Business Management System (KTDC) Insert the notification screen.

In addition, referring to the daily variable data generation, it collects data about the change of the subscriber to generate the daily variable data for the subscriber based on the processing date of the subscriber. The daily change data for the subscriber is entered into the terminal of the sales window of the telephone company connected to the TSIS. The input daily variation data is transmitted to the 114 guidance system to extract the daily variation data for guidance according to the processing reference date. In the extracted daily variable data, the name of the company desired by the subscriber is lost by converting the name of the organization desired by the subscriber to the name of the organization according to the guide personality. Therefore, in the daily change data of the electronic telephone book, the daily change data for the customer management system was referred to to record the group name desired by the subscriber. In addition, the industry code is not accurately recorded in the daily change data, so the industry code in the daily change data of the electronic telephone book is included.

The daily change data for the electronic telephone book is generated by the customer management module accumulating the daily change data and using the daily change data key of the 114 information system for the desired company name. The generated daily variable data is checked by telephone inquiries to the variable subscribers by the data processing personnel, and the corresponding industry code is recorded.

The database and currentization are modules that create a new service database because the subscriber's change information is inserted with daily change data and service files that occur daily. According to the classification of the change data, the change code is analyzed for the names of people, industry groups and new number guide files to maintain the current file.

Database modernization can be divided into analysis of variable code and update by actual analyzed code (UPDATE). Various kinds of daily variation data can be interpreted as simply inserting, deleting, or modifying the variation code.

Currently, the service retrieval system's database has the same structure and contents as the DB management system's copy and output, so there is no need to re-code the daily change data. The service retrieval unit may be made current based on an analysis result of the change code (called a batch-code). As a result of code analysis, it is not necessary to overload the service search module when providing a service, thereby providing a quick service.

In addition, in order to operate the electronic directory system (EDS: Electronic Directory System) on the service retrieval unit, the operation management module converts a process related to a daemon process and manages the current service retrieval subscriber's situation. You can find out using

The statistics module constructs statistical data such as user usage, service type, and usage time for the electronic phone book service, and is classified and provided as once and monthly statistics, current day statistics, and access call repayment. The company will collect data on their industry and apply it to the Inquiry Guide Server developer fee in the future. It is used as data (advertising statistics, usage propensity, etc.) to improve the industry service.

Statistical data conversion is in charge of converting the recording file serviced as an option of the submodule into the form required for statistical processing and updating the recording file (UPDATE). In the statistics DB construction, the statistics construction program calculates the mail service result, and stores the access time for each service and the number of access for each time in a file. The daily statistics build stores the records that are the statistics of the day in the morning every day. Industry service data construction builds data on input query and advertisement selection of users of industry service. The statistics service displays monthly and daily statistics data for each service to operation staff or system users, and supports distribution and printer output in graphs.

The communication processing module is provided with VIDACII, ECOM25 and MULTIX25. When the VIDACII is connected to a port, not only the service registration provided for the subscriber is registered but also the status of the port currently being used, and other service changes and The delete list can be conveniently used by the operator.

When the ECOM25 'is connected to the address of the ECOM25, it provides routing path setting for subscriber calls, parameter setting and change for each X.25 port, and monitoring for input / output ports.
