기업간 비즈니스 거래를 하기 위해서는 B2B(Business to Business)기업이 지원하는 업무 프로세스에 관한 정보와 업무 정보 교환을 위해 기업의 기술적인 사항을 정의하고 거래 기업간에 비즈니스 거래를 위하여 거래 파트너간 합의된 상호작용을 정의한 문서가 필요하다. 이러한 문서를 XML 기반의 개방형 전자상거래 프레임 워크인 ebXML(electronic business XML)에서는 기업의 비즈니스 협업능력을 정의한 전자를 협업 프로토콜 프로파일(Collaboration-Protocol Profile:CPP)이라 하고 거래 기업간에 비즈니스 협업 상호작용을 정의한 후자를 협업 프로토콜 약정서(Collaboration-Protocol Agreement:CPA)라고 한다. 본 논문에서는 ebXML에서 거래 기업간 상호 운용성을 증대시키는 CPP문서를 효율적으로 저작 할 수 있는 생성기와 거래 기업들의 CPP 문서들을 기본으로 상호 협업을 정의한 CPA 문서를 저작 할 수 있는 Composer 시스템을 설계 및 구현하였다.

These days, XML is accepted and used to e commerce market broadly. But by reason of XML document can exist same form logically but several other forms physically, several problems can happen in application that judge effectiveness as physical form such as XML digital signature. Therefore, it is recommending to propose and use canonical XML algorithm to change identical XML document physically equally logically in W3C to solve this problems. We implemented system that nm Canonical XML algorithm that suggested in W3C that can change to mon elaborate regular document. Thus, interoperable with other application that takes W3C recommendation Also, as well as use in digital signature system for web service is useful, use in several system that physical identify is required when it exchanges na document for web service interoperability are considered to be valuable. Moreover, Adding the transformation ability between universal encoding scheme and EUC­KR that is internal encoding scheme should be Canonical XML Algorithm that is suited to internal circumstances, and this should be a foundation technique of international interoperability confirmedness.

For workflow systems using XML documents for saving workflow process definition and especially for XML-based worflow systems, a repository needed to provide control for XML documents. The repository allows uniform access to shared data and facilitates integration among tools in workfolw systems. An XML repository gives the best solution to maintain, exchane, and modify the workflow process definition meta data, which is in the form of XML documents . The XML repository, where users can lookup the worflow definition objects, serves as the metadata foundation of the workflow system. In this paper, we developed for XML Repository(called REPOWO : REPOsitory for Workflow) that can store, delete, search and transform XML documents. REPOWO is implemented by combining EJB components based on RDBMS. By REPOWO, workfolw process definitions, data type definitions and transition informations can be easily manage.

PDF는 미국 어도비 시스템즈(Adobe Systems) 사에서 만든 전자 문서 파일 포맷이다. PDF에는 일반 문서 및 문자, 도형 그림, 글꼴 등을 포함할 수 있으며, 동일한 문서를 컴퓨터 운영체제와 관계없이 모니터, 프린터 등의 출력 장치로 같은 모습으로 출력하기 위한 목적으로 개발되었다. 현재 거의 모든 운영체제에서 PDF 문서를 읽거나 인쇄할 수 있으며, 온라인 및 오프라인 환경에서도 쉽게 PDF 문서를 공유할 수 있으며, 보안성이 높아 공공기관, 연구소 등에서 자료를 배포할 때 많이 사용되고 있다. XML은 사람이 쉽게 읽을 수 있고 컴퓨터와 같은 기계가 쉽게 판독할 수 있는 형식으로 부호화된 문서를 작성하기 위한 일련의 규칙을 정의하는 데 사용하는 마크업 언어로서 W3C에서 정의하였다. 현재 XML은 인터넷 상에서 데이터를 표현 하거나 교환, 저장, 검색할 때 가장 널리 쓰이고 있다. 본 논문에서는 PDF 문서를 인터넷 상에서 쉽게 활용하도록 도와주며, XML 데이터 처리가 가능한 응용 프로그램에서 PDF 문서를 활용할 때 쉽게 사용할 수 있도록 도와주는 PDF-to-XML 변환 소프트웨어를 구현하였다.

급변하는 기업환경에 적응하고 경쟁력을 강화하기 위하여 정보 통신기술을 활용하여 업무처리 시간 및 비용을 절감하고, 품질을 향상시키기 위한 대안으로 EDI 시스템이 출현하였으며, 그중 다양한 문서구조 표현이 가능한 XML을 활용한 XML/EDI 가 급속하게 확산되고 있다. EDI 시스템에서는 보안 서비스를 제공되고 있으며, 그 중 전자서명은 중요한 비중을 차지하고 있다. XML을 이용한 전자서명 기법이 W3C에서 제안되어 표준호가 진행되고 있으며 이는 EDI 시스템에서 유용하게 이용 가능한 기술이다. 본 논문에서는 XML 전자서명을 XML/EDI에 적용하여 시스템을 설계하였다.

Recently, due to the popularity and explosive growth of the Internet, the information exchange is increasing so rapidly over the Internet. Also the XML is becoming a standard as well as a major tool of data exchange on the Internet and thus we propose the new indexing technique for evaluating a path-oriented query and design and implementation of Path-oriented Query Processing System to give useful for users. In proposed indexing technique, which combined a binary trio structure with a path signature file to improve performance of XML document retrieval.

Electronic document processing using EDl (Electronic Data Interchange) must exchange documents using VAN (Value Added Network). However. the use of exclusive software needs alteration of a new document and the use of VAN(Value Added Network) demands an exchange of document and high cost for maintenance. Due to these problems, the existing EDI (Electronic Data Interchange) is turning into Web-based EDI (Electronic Data Interchange). This paper suggests techniques that change EDI (Electronic Data Interchange) messages which exist in two relational databases into XML (extensible Markeup Language) using the JDBC bridge. Also this paper proposes a method that recovers schema using converted XML (extensible Markeup Language) file, and a method which inserts an original record into a declared table. This solves the limitation of an original method that have to use sane database management system and also overcomes the problem in certain circumstances where the EDI (Electronic Data Interchange) exchange does not work.

Since XML allows users to define any tags, XML documents with various structures have been created. Accordingly, many studies on clustering and searching the XML documents based on the similarity of paths have been done in order to manage the documents efficiently. To retrieve XML documents having similar structures, the three-dimensional bitmap indexing technique uses a path as a unit when it creates an index. If a path structure is changed, the technique recognizes it as a new path. Thus, another technique to measure the similarity of paths was proposed. To compute the similarity between two paths, the technique compares every node of the paths. It causes unnecessary comparison of the nodes, which do not exist in common between the two paths. In this paper, we propose a new technique that minimizes the comparison using signatures and show the performance evaluation results of the technique. The comparison speed of proposed technique was 20 percent faster than the existing technique.

Because XML is a W3C standard and has characteristics like platform-independent, it has a critical role in e-commerce. Business rules and Procedures should be standardized for efficient B2B integration. But a lot of companies are its own XML documents instead of standard documents. Therefore many organizations try to make standards for e-commerce based on framework. In this paper, we designed and implemented XML Messaging System based on TCP/IP protocols. This system are designed by module. Because, it is easy to extensibility of system. So we can more easily and efficiently build e-commerce system based on this XML messaging system.

New methods for storing and retrieving semi-structured data such XML documents has been recently studied. In this paper, we concern querying of XML data stored in relational tables. We first describe a method of querying XML documents using Oracle XDK, especially XSQL Servlet. We then apply the method to XML documents describing book information.
