Description

How to build an interactive electronic technical manual system in a heterogeneous distributed environment

The present invention relates to a management system that can structurally store and manage data necessary for constructing an Interactive Electronic Technical Manual (IETM), and in particular, when using IETM while maintaining a distributed state of each data. The present invention relates to a method for constructing an interactive electronic technical manual system in a CALS heterogeneous distributed environment, which can efficiently retrieve, appropriately process, and provide data to a user.

IETM is a technical manual written in digital form that provides the user with an electronic window form of hypertext syntax and is organized by an automated authoring tool. The IETM, a collection of information for troubleshooting and maintenance, is a key technology for CALS in engineering terms. IETM is a technical work used for the installation, operation, maintenance maintenance, testing, repair, overhaul and logistics support of ships, aircraft, equipment or maintenance materials. It provides a path to provide an effective and comprehensive hypermedia-based technical document for using technical data. When these IETMs are built in conjunction with the Knowledge-Based Expert System, synergies can be expected in their functionality.

Among the various technologies required to build an IETM, an in-depth study is an IETM database that stores and manages IETM information in a structured and efficient manner. A general approach to building a conventional IETM database is to store and manage all data constituting the IETM in a centralized database through a content data model (CDM). The IETM database construction method causes a lot of problems when the volume of data becomes huge. In other words, if the volume of data becomes huge, the IETM database, which has to manage all data centrally, incurs data management overhead.

Conventional techniques for constructing an IETM database are centered on efficiently storing and managing data in a single database, and there is no research on a solution to mass data.

Conventional IETM database construction techniques focused on efficient databaseization of IETM data through a content data model. In other words, by focusing on building the database itself, research on data management that can occur naturally as the volume of data becomes enormous is insufficient.

Accordingly, the present invention introduces the main functions of a multi-database management system such as query interpreter, distributed transaction service, query result integrator, etc. to manage heterogeneous and distributed data and to provide transparency on the location and storage format of each data. In order to efficiently search for IETM element data, we invented a catalog system that manages the content data model and metadata about the data.

Accordingly, an object of the present invention is to efficiently search for and manage necessary data in an IETM system without maintaining heterogeneous and distributed data in a single database to solve the overhead of data management. To provide an interactive electronic technical manual system in a CALS heterogeneous distributed environment.

In order to achieve the above object, an interactive electronic technical manual system in a CALS heterogeneous distributed environment includes a data source conversion system for including the main functions of a multiple database management system; A content data model / metadata catalog system for managing a content data model for efficiently storing and managing directory information and dictionary information on electronic technical manual data, and for cataloging and managing metadata; And a local data adapter for retrieving and providing the necessary data according to the requirements of the data source conversion system.

In addition, the interactive electronic teaching method in the CALS heterogeneous distributed environment according to the present invention is a data source conversion system when the interactive viewing software stores recent information using a memory and a user requests information that is not owned by the user. Querying the request information; A second step of requesting, from the first step, the hierarchical information and metadata of the content data model of the information to the catalog system to interpret the query; A third step of analyzing the query based on the information received from the catalog system from the second step and transmitting the partial query to the appropriate local data adapter through the transaction service; A fourth step of transmitting, from the third step, a result of the transaction service received from the local data adapter to the SGML coating module according to the hierarchical structure of the content data model; And a fifth step in which the SGML coating module transmits the result to the query result integrator from the fourth step and the interactive viewing software integrates the desired form and returns the result. Characterized in that the computer-readable recording medium for recording the program.

2) Multiple Database Management System Functions and SGML Coding Module 20: Query Analyzer 21, which analyzes information needs of clients, and Transaction Service 22, which services distributed transactions to receive data from multiple data sources. Transaction Service), an SGML Coding Module (23) for processing and modifying the results received from the data source to conform to the IETM system, and a plurality of results received from the SGML Coating Module (23) into one result. The query result integrator 24 is configured as a View Integrator.

2. CDM / Metadata Catalog System (2; CDM & Metadata Catalog System)

It manages the content data model to efficiently store and manage directory and dictionary information about IETM data, and manages metadata by cataloging it. The CDM / Metadata Catalog System (2; CDM & Metadata Catalog System) is divided into three modules:

1) CDM / Metadata Authoring & Registration Tool (30; CDM & Metadata Authoring & Registration Tool): Provides tools for authoring and storing content data models and tools for registering metadata.

2) CDM / Metadata Database (40): Stores and manages content data models and metadata.

3) CDM / Metadata Manager (50; CDM & Metadata Manager): Manages the content data model. In addition, the metadata is cataloged and managed for searching for necessary metadata.

3. Local Data Adapter (3;

This is a function module that manages the local data source that stores each data constituting the IETM, and has the function to interface with the file system or database of the local data source, and the data source conversion system (1). Function to retrieve and provide necessary data according to the requirements of

The operation scenario of the interactive electronic technical manual system of FIG. 1 may be represented by the sequence diagram of FIG. 2.

Interactive viewing software (4; Interactive Viewing Software) is using the memory to store the latest information. When the user requests information that is not owned by the user, the data source conversion system 1 is queried (101, 102).

In order to interpret the query in the data source conversion system 1, the catalog system requests the hierarchical information and the meta data of the content data model of the corresponding information (103, 104). The query is analyzed based on the information received from the catalog system, and a partial query is sent to the appropriate Local Data Adapter (3) through the transaction service (105, 106, 107).

The transaction service sends the result from the Local Data Adapter (3) to the SGML Coding Module (23) according to the hierarchical structure of the content data model, and the SGML Coating Module (23) sends the result. Is sent to the query result integrator 24 and the interactive viewing software 4 integrates the desired form and returns the result (108, 109, 110, 111).
