Since SGML complies with international standards, files written in compliance with s GML can be completely transferred between users of different systems. However, SGML files themselves are hierarchical designs and cannot be directly compatible with the familiar associations Database system. The structure of S g ML file often includes tree structure and graphics, which are very difficult to design and maintain in the relational database system, mainly because Because the relational database system lacks rich data modeling capabilities, each bit (fie 丨 d) can only record a simple data type, not a collection or another piece of data (object). And 'data model and The environment for processing data is inconsistent, and the objects of the application cannot be obtained directly from the relational database, but need to be converted through object records (rec 0rd). To store SGML files in the relational database system, it is necessary First save the hierarchical structure of the SGML file into a table and establish the correlation between the tables. In this way, when the file is inquired, the efficiency of the system will be reduced. 5-2 Objects and Summary of the Invention The main object of the present invention is to propose an object-oriented database system to store and manage SMG files, to make technical documents reasonable and easy to integrate.

Of course, the system and method of the present invention are applicable to any object-oriented database system, and are not limited to the system described in this embodiment. Interesting J-oriented data base The basic requirements of object-oriented are the characteristics of inheritance, polymorphism, and encapsulation (E n c a p s u 1 a t i ο η). The object-oriented database (〇 b〗 e c · Oriented DataBase, OODB) is the objectization of the database's stored text, so that the object (0 b j e c t) becomes the access unit of the database. Therefore, the object-oriented database must adopt the object-oriented data mode (Object Oriented Data Mode) to develop the database system to save and process all kinds of complex objects, because these complex structural objects are difficult to use ordinary relational relationship structure to Means.

Description of the invention (Object-oriented information The library must therefore support new data types and operations, and support abstract data types (AbstractDataType) and user-defined data types (User-DefinedType). Moreover, it must have more semantic concepts, such as generalization And aggregation (Aggregation) and other semantic concepts. In addition, the object-oriented database must also support the processing of multimedia data, such as graphics, video and audio materials. In the embodiment of the present invention, WOO_DB 13 and general objects The characteristics of the guided database have many advantages. For example, the storage of data is based on objects. Therefore, the data of the same object is not divided into many tables to store like the relational database. Custom data types are available for users. At the same time, they also have the ability to inherit. Any data stored in W 0 0-DB 1 3 is persistent. Therefore, users do not Pay special attention to the update of data. W 0 〇_ DB 1 3 will automatically record the changed data of the parent and store it automatically. The most important thing is that WOO-DB 13 can directly record the complex data structure without disassembling it. Into separate pieces. Application designers can design the data structure according to the actual needs of the application. Using an object-oriented database system allows the application to be directly and tightly integrated with the database, so that the application does not need to spend too much Extra effort is put into the communication and data conversion of the database system.

The WOO-DB 13 system can be divided into two types: stand-alone version and master-slave version. The architectures are shown in Figure 2A and Figure 2B. As shown in Figure 2A and Figure 2B.

Description of the invention () ~~~ Computer host or server on the network side. The structure and properties of the data " Before explaining how the present invention constructs the electronic file of SGML or HTML on the above W OO_DB system, it must first explain how the present invention analyzes the structure of the file, especially the SO ML. Basically, SGML will be a file It is divided into three parts: structure, text, and style. The stipulated content is mainly the relationship between the structure and the text. Among them, the structure is mainly described in the file of the file type definition (hereinafter referred to as D T D, D o c u m n t Type Definition). This DTD describes the structure of the document 'like a graphic pattern to depict the relationship between the types of information and niches' to provide a preset structure for the text paragraphs in the document, such as chapters, titles, titles, topics, etc. The relationship between individual text paragraphs is also specified. For example, 'this article must be placed after the title, each column must contain at least one item, etc. These rules can ensure the consistency and logical structure of the article. That is, every document has a D T D. A D T D contains the provisions of various marking content and their relationship. The text is the information itself. It contains the title, paragraphs, lists, blocks, graphics, and audio. It does not have to be in this document. It can be a paragraph in another document on the Internet. Assume that the method with DTD structure in the body is called "tag", and these tags appear in the file structure (please read the precautions on the back before filling this page). ) (21 OX 297 ^ ¾) 475125 A7 B7 V. Description of the invention (the beginning and end of each text paragraph to establish the structure of the various markup content in the SGML or HTML file surrounding the text. Some authors who write SGML files Make a list for easy writing and use. The format refers to the file format, but SGML itself does not make any stipulations on the format of the file. 'So most systems still maintain their own special file format. The sub-standard bureau only .t-eliminated in the Hanzhusheyinf. So the 'documents have different formats according to their nature, such as letter, plan book' book 'and official documents, etc. each have different file structures. These structures are It is defined in the DTD. The DTD is the backbone of all SGML systems and can be stored separately from the files. Files with the same structure can share the same DTD. The components of the DTD include the elements (Ele ment), attributes (Attribute) and entities (Entity), and elements are the most basic architectural unit in the DTD, so after defining the environment, you must start to study the file type, and then define the elements. After the DTD is defined, The data structure of 〇〇DB can be defined at the same time in accordance with its specifications. When the GML file is written in accordance with the DTD structure, it must be added with a mark and becomes a ~ case, (Document lnstance, DI).

Correspondence processing from ER schema to OOdb architecture can be transformed from a conventional semantic mode to an object-oriented mode. The conversion steps are as follows: First, ER entity types and associated cancers (r e 1 a t 〇 s h i p t y p e s) are mapped to object-oriented categories (0 _ 0 c 1 a s s). In this way, the hierarchical relationship of the structured electronic document is provided in the object-oriented category. ; --- Γ --- 0 ^!

And define and produce the dtd and the mark that must be used to complete the format of the document data entity storage and ^ According to the DTD of the document, the various parts (such as chapters and sections) that make up the document are stored in an object-oriented database. The main purpose of this approach is to make the document query more efficient. But how? If an SGML λ instance is mistakenly stored in the object-oriented database, it is necessary to rely on the document structure reading device of the present invention.

1T

The document structure reading device is mainly used to identify the various types of objects (such as chapters, chapters, and sections) in the document example. The objects are stored in the object-oriented database and the associations between the objects are established. The file structure reading device of the invention can be implemented by using tools such as Windows 95, BQHand cZ 3.0 · W′-DB DBM τ〇〇ι. When the program starts to execute, the file structure reading device will ask the user to enter the WOO_DB database file name and the SGML file example file name. The eaves type must be under the directory being executed, and it must be: The sub-directories in it have the following files: WOO-DB: Body Bank File, SGML Cases' and all the graphics files related to the document cases. After confirming that everything is correct, the file structure is read and cracked. 3 It will also be concealed and stored: 475125 A7 ___B7 V. Invention description (-) When the program is completed, the screen will display "Document scanning completed" The message indicates that the scan was successful. The file structure reading device uses stacking to record and identify various types of objects in the document example. A simple example is used to illustrate this approach. Suppose a document example is: &lt; book &gt; &lt; title &gt; sgml file I &lt; / TITLE &gt; &lt; AUTH〇R &gt; PETER &lt; / AUTH〇Rx / b〇〇K &gt; Suppose the DTD defines "B 〇 ο κ, this element has only two elements, one is" Τ I τ L E '', the other is '' au Τ H Ο R ,. If the database has already established the following categories based on the d TD used in this SGML file, where "Β 〇〇κ ， The attributes of the category are "T j TL Ε," and "AUTHOR", and "AUTH〇R" is another category object, whose attribute is "string". When the file structure reading device is executed, first create One stack (STACK) Buffer (BUFFER), as shown in Fig. 3. Stack 31 is used to store the label of the document example (such as &lt; b 〇〇κ &gt; 3 2), and buffer 34 is used to store the file example except Data other than the mark (such as “SGML file 1” 3 5). When reading the file, if it reads the initial mark, it will be pushed into the (Push) stack 31, otherwise it will be stored in the buffer 3 4. When the end mark is read, the data is read out from the buffer and the mark in the stack is pushed out. Paper ruler 21 OX 297 ^ ¾) ------- 475125 A7 __ B7 V. Invention Explanation () According to this, "&lt; / τ ί τ LE &gt;, before this mark, the data of stack 3 i and buffer 3 5 will be shown in Figure 3. And when the file structure reading device 11 scans to "&lt; / TITLE &gt;", then it means "&lt; TITLE &gt;", and it has ended 'so the file structure reading device 11 will push the stack 3 1 first (ρ 〇P). Then identify the attributes of &lt; τ I τ L E &gt;, and determine whether it is an object or an attribute in an object. Then, based on the data in the buffer, an object or attribute corresponding to &lt; TI T L E &gt; is created in an object-oriented database 13. Finally, establish associations between objects. In this example, since "&lt; Τ ITLE &gt;, is an attribute of &lt; Β 〇〇K &gt; ,,, the file structure reading device ii will first create a" B 〇〇κ ,, " Object, and then store the data of "TITLE" in "TITLE" of "ΒΟοκ". However, if the read symbol represents another object (such as "<AUTHOR>"), the document structure reading device n will directly establish this object, and then establish its association with other objects. Therefore, after the execution of the file structure reading device 11 is completed, the object-oriented database 13 will generate an object of “β 〇 0 K” and an object of “a ϋ Τ Η 0 R”, of which the “TITLE” of the “BOOK” object The attribute value is "SGML file one", the "string" attribute value of "A Τ Τ Η 0 R" is "peter", and the "A ϋ TH 0 R" of the "β Ο Ο K" object is linked to “A u TH 〇R” In the object.

The shell material to be found is searched out. Since the database is about to be built into categories (C 1 as S) such as books, articles, flats, festivals, pictures, etc., it reads the file in the file structure. Device 1 1 completes reading the file. Example 4, it will be built into the category it belongs to according to the mark on the document example. When querying the program, you can select the category to which the keywords in the hall are searched, such as books, articles, chapters, sections, or drawings. If so, you can query the content in the database. 2 Use object-oriented data Library 1 3 The document query interface and omserr.h, program of the present invention. Before dealing with various different classes, you must first create a corresponding structure. The provided header file is the ornsapih library (Library) and the slot is 0 msbc32.1ib. Don't deal with it in different ways. Before making various categories, first direct the object to all the classes (Struct) in the database 13. For example: typedef struct Book One S // This is the structure corresponding to Β ο 〇k {omU 1 Β Β — Β title [64]; omUlB B_Author [64]; omU 1 Β B—Editor [64]; omU 1 Β B—Copyright [64]; System Α7 '^^ _ Β7 _________ 5.

The file search § Xen interface 12 includes various categories of processing. When the pull-down menu selects "Books", the user first enters keywords and presses the query button to enter the category "Books." In the processing procedure, execute the processing procedure of the category "Book,". Do some preprocessing of the database when querying, such as: omlnitializeO &quot; the beginning of the database 〇mTransact () &quot; the beginning of the transaction 〇mConnectOB () / / Link database Next, because the category to be queried is "Book", you must first find the "Book" by the following procedure. 4: Paper size rule, Tns (210X 297 ^ t) '--- (Please read the notes on the back before filling this page)

^ The context of the file, search information. Think of a document file as a database that you can search and analyze. SGML allows you to set a variety of display styles for various files you make. It will force the descriptive markup of the file to fit the logic and expected file structure. It also supports an infinitely variable file structure, so users You can design different file structures for each category of information (news bulletins, technical manuals, catalogs, reports, and memos) without changing the content of the article. Because the present invention builds structured documents on an object-oriented database, it can effectively solve the shortcomings of the conventional application-related database, so that the system and the database management system can be closely integrated. And the related objects can be obtained directly, which can improve efficiency. It also simplifies the storage and processing of various structures such as trees and diagrams that often appear in structured file structures. More importantly, because the object-oriented library supports the use of the user-defined type (User-Defined Type), the two, and the structure are accessed in a consistent manner, that is, the database storage form and development The form is consistent. The above are only the preferred embodiments of the present invention, and have achieved a wide range of practical effects.
