In recent years. XML applications are being developed in diverse area. Especially, development of XML document repository system associated with database is carrying out widely. The previous researches of XML repository system have several defects which are update and retrieval limitations for the XML document, design limitation for a formal retrieval algorithm and data redundancy. In order to solve the above problems. in this paper, we suggest relational database schemes for overcoming limitations of updating, retrieving, and rebuilding document. And suggest query translation strategy using two-phase translation that consists of pattern analyzing phase and SQL generating phase.

For the implementation of CE(Concurrent Engineering), the TDMS(Technical Document Management System) which integrates design and manufacuring information, is required. In this paper a drawing information management system, one of the essential modules for the TDMS has been developed. The system is operated in SUN SPARC II workstations. A CAD software called CIMCAD-2D is used for the storage and management of drawings. Relational DBMS ORACLE is used for the development of information data bases concerned with drawings. As an integration tool, the multi-media software called LINKAGE is used. Various functions for drawings and concerned information have been developed with the internal language CIMSHELL and SQL $^*PLUS$.

There are increasing needs for an individual or enterprise to interchange documents electronically through communication network to enhance the efficiency of business, according to the rapid progress in the construction of communication network. UN has established and distributed the standards for electronic documents to facilitate rapid and accurate processing of business. In this paper, we present the design and implementation of an integrated system for processing documents that conform to the electronic document standards. This system consists of three subsystems, which are an EDI parser for checking syntax, an EDI document editor, and an EDI directory viewer for referencing syntax of an EDI document. Integrated usage of these tools can afford the composition of correct EDI documents more rapidly and conveniently.

Recently, network overload is greatly increased with explosive use of internet. So the Hyper-Text Transfer Protocol(HTTP) is required improve of performance for decreasing of latency on the web document processing. The P-HTTP is one of the improved mood of He HTTP and has pipeline structure, but performance of the P-HTTP is decreased on interaction between the TCP and P-HTTP. Modification of structural design of the HTTP is not enough to improvement this problem. In this paper, we analyse performance of the HTTP and P-HTTP, and propose a new method on improving HTTP latency for the efficient web document processing.

In this paper, we designed and implemented the general-purpose document repository manager for the ebXML-based e-business framework that support the rapid translation of various types of documents and provide the flexibility corresponding to the framework changes. Also, we automated the manually-processed e-business document translation process by designing the adaptor module for the interoperability of legacy systems. In the regards, our designed general purpose document manager makes it possible to integrate the existing e-commerce systems that are operated on the heterogeneous frameworks, and can be used on global e-business solution.

With explosive growth in the area of the Internet and IT services, various types of e-documents are generated and circulated. An e-Document is a sort of electronic records which a organization performs works and goals. In this study, we propose a security algorithm for secure use and distribution of e-documents. Especially, the proposed method can be applied to generate digital signature which can guarantee authenticity, integrity, confidentiality of an e-document and authenticate authorized users. Also, we can get higher security level as using a smart card that provides highly storing capacity and security. We carried out an experiment to verify efficiency and security of the proposed method.

Generally, Diagram Systems related XML document are designed for certain purpose. It is also difficult to create DML document, because there is no definition of diagram component. In this paper, we design and implement the diagram system to execute the XML document. This diagram system defines the diagram component with WYSIWIG concept ,md it is designed to generate DML document automatically. Therefore, it is possible to develop diagram efficiently and maintain consistency by definition of syntax about diagram with DTD. And this system uses the concept of VPL(Visual Programming Language) to check syntax and semantic about diagram sentence. Though this system, DML documents can be generated easily, and it can also check syntax and perform semantic.

Theoretical developments in the information retrieval have offered a number of alternatives to traditional Boolean retrieval. Probability theory and fuzzy set theory have played prominent roles here. Fuzzy set theory is an attempt to generalize traditional set theory by permitting partial membership in a set and this means recognizing different degrees to which a document can match a request. In this study, an experimentation of a document retrieval system using the fuzzy relation matrix of the keywords is described and the results are offered. The queries composed of keywords and Boolean operaters AND, OR, NOT were processed in the retrieval method, and the method was implemented on the PC of 32bit level (30 MHz) in an experimental system. The measurement of the recall ratio and precision ratio verified the effectiveness of the proposed fuzzy relation matrix of keywords and retrieval method. Compared to traditional crisp method in the same document database, the recall ratio increased $10\%$ high although the precision ratio decreased slightly. The problems, in this experiment, to be resolved are first, the design of the automatic data input and fuzzy indexing modules, through which the system . can have the ability of competition and usefulness. Second, devising a systematic procedure for assigning fuzzy weights to keywords in documents and in queries.
