As B2B (Business to business) develops swiftly, at home as well as in other advanced countries, plans for activating Electronic business are made and proceeded in a national viewpoint. However, it is essential task for the construction, advancement and activation of B2B framework to make an efficient search for differently built -up data from B2C and thus to look for optimal business partner suitable for his/her own business. For this, in the last Aug. of 2001, government has also referred to ebXML, the exchange model for electronic business data based on XML, as a suggestion for B2B framework. The purpose of this study is to develop search system for efficient choice of business partner and this will play an important role for data processing and competitiveness strengthening of small and medium enterprises. Meanwhile, this system is built up by using systemic characteristics registered in ebXML Registry/Repository and ‘question-expanding’ searching ways based on the particulars of business profiles for both objectiveness and maximum efficiency of search result.

In data mining, having access to large amount of data sets for the purpose of predictive data does not guarantee good method, even where the size of Real data is Mobile commerce unlimited. In addition to searching expected Goods objects for Users, it becomes necessary to develop a recommendation service based on XML. In this paper, we design the optimized XML Recommender product data. Efficient XML data preprocessing is required, include of formatting, structural, and attribute representation with dependent on User Profile Information. Our goal is to find a relationship among user interested products from E-Commerce and M-Commerce to XDB. Firstly, analyzing user profiles information. In the result creating clusters with analyzed user profile such as with set of sex, age, job. Secondly, it is clustering XML data which are associative products classify from user profile in shopping mall. Thirdly, after composing categories and goods data in which associative objects exist from the first clustering, it represent categories and goods in shopping mall and optimized clustering XML data which are personalized products. The proposed personalized user profile clustering method has been designed and simulated to demonstrate it's efficient.

While on-line shopping is increasing, the "Consumer Protection Law in Electronic Commerce" obliges each internet shopping mall to provide its business information. Although most internet shopping malls provide their business information in the semi-structured format on the bottom of their homepages, the attributes and expression forms of business information are different each other. It makes consumers difficult to identify their business information and lowers public confidence. Hence this study proposes three approaches - HTML-based structure, XML-based structure, and XML data island-based structure - to structuralizing business information for correct expression. The experiment results showed that the business information extraction time by XML data island-based structure is independent of the size of the web document, while the time by HTML-based structure is dependent on the size. By comparing the business information extraction times, we show that XML data island-based structure is more efficient and effective than HTML-based structure.structure.

As the automation of ship production system proliferates, it is unavoidable to move the real machinery, facility, application software, and virtual environment from the heterogeneous data environment to the integrated one. However, it is a prevailing situation that each component operates under the different environment, due to the inability of interchanging the data in a structured manner between the components. The issue is obstacles to improvement of the application system. To facilitate seamless exchange of data among the manufacturing systems, STEP, PDML, and XML has been tried by other studies. This study has investigated how XML data can be applied to exchange the data among the ship production system components. XML data is applied to the forming shop in shipyard to overcome the present difficulties on sharing and exchanging of the information. An example of forming information is represented by XML to demonstrate the feasibility of the proposed approach. In addition, an application of XML information applicable to virtual factory and electronic work order sheet is included.

ebXML (Electronic Business using extensible Markup language), sponsored by UN/CEFACT and OASIS, is a modular suite of specifications that enables enterprises of any size and in any geographical location to conduct business over the Internet. Using ebXML, companies now have a standard method to exchange business messages, conduct trading relationships, communicate data In common terms and define and resistor business processes. It is the mission of ebXML that provides an open XML-based infrastructure enabling the global use of electronic business information in an interoperable, secure and consistent manner by all parties for creating a single e1ectronic electronic market. This paper briefly overviews the concept of core component, context, assembly rule and context rule. Then, It designs by standard specifications of ebXML core component commonly used in an industry and among industries, and assembles business messages by using XML schema. Therefore, it suggests the mechanism which effectively exchanges business messages among the trading partners. This paper designs core component by using only three business messages of retail industry : orders, dispatch report, sales report.

A methodology is proposed to share the design information of a gear drive using XML (eXtensible Markup Language). XML is the standard language of the next generation and can be used as a neutral and unique format shared by various Web applications. Since XML is a platform-independent meta-markup language, it is possible to reduce the additional programming efforts for Web applications by using the standardization of technical terminologies. In this study, the structure of design information about gears, shafts, keys and bearings in a gear drive has been made and the terminologies used in the gear drive design process have been authored. The XML DTD(Data Type Definition) for the gear drive design has been declared and the usage of the XML application has been shown.

인터넷을 통한 응용 프로그램의 통합과 다양한 정보의 등장으로 인해 정보를 원활히 교환하고 관리 저장할 수 있는 정보 시스템의 요구가 급증하고 있다. 이에 대한 해결책으로 등장한 XML은 기존의 데이터베이스 관리 시스템과 연동하여 다양한 플랫폼과 이질의 데이터에 관계없이 저장과 관리가 용이하며, 데이터 교환을 최적화 할 수 있다. 본 논문에서는 XML 문서의 논리적인 구조정보를 표현하는 DTD와 Database Schema 간의 변환구조를 MMDB에 저장하므로써 XML DTD를 기반으로 Database Schema를 설계하고 XML DTD건의 변환 구조를 효율적으로 관리하는 방안을 제시한다. 이렇게 함으로써 빈번하게 사용되는 XML DTD 변환 정보를 메모리에 상주하게 되고, 그 결과 디스크 출입회수를 줄이게 되어 XML을 사용하는 응용에서 XML Data에 대한 처리 효율성을 높일 수 있게 된다.

In this paper, we implement the XML modeling and data modeling by the class diagram that is made by the use case after drawing out the sequence diagram. For the XML modeling, the guiding line to map the UML classes on the XML document will be presented. Then, an example to generate the ie DTD from the UML classes will be shown under the presented guiding line. In the data modeling, the transformation method from the In classes into the object-oriented database also will be proposed. Finally, we will give an example developed by the Proposed transformation method.

A XML Instance repository model based on the Edge-Labeled Graph is suggested for storing the XML instance in Relational Databases, This repository model represents the XML instance as a data graph based on the Edge-Labeled Graph, extracts the defined value based on the structure of data path, element, attribute, and table index table presented as database schema, and stores these values using the Mapper module, In order to support querry, XML repository model offers the module translating XQL which is a query language under XPATH to SQL, and has DBtoXML generator module restoring the stored XML instance. As a result, it is possible to represent the storage relationship between the XML instances and the proposed repository model in terms of Graph-based Path, and it shows the possibility of easy search of specific element and attribute information.

XML DBMS는 XML 문서의 직접적인 접근과 문서의 부분, 문서와 그 문서의 부분들을 통한 질의를 할 수 있는 능력을 가져야 한다. 이러한 XML DBMS의 사용은 복잡한 계층적 관계의 범위로부터 데이터를 얻어내는데 특히 유용하게 사용될 수 있다. 일반적으로 XML DBMS를 구축하기 위해서는 다른 DBMS 위에 덧붙이거나, 처음부터 만들거나, 새 제품을 구입할 수 있을 것이다. XML DBMS를 처음부터 새롭게 생성하는 것은 메모리 할당과 문서 조각의 효율적인 검색을 신중히 생각해야 한다. 다른 DBMS 위에 XML DBMS를 구축하는 것은 빠르게 구축할 수 있고, 하부를 구성하는 DBMS의 저장소를 사용할 수 있다는 이점이 있다. 또한 현재 존재하는 애플리케이션들과 기존의 자료와 통합이 쉬울 수 있다. 이러한 관계형 DBMS는 현 시장에서 상당히 많은 부분을 차지하는 제품으로서, 새로운 DBMS로의 이전을 하기 위해서는 상당한 어려움이 있다. 이러한 제약을 해결하기 위하여 기업에서 선택해야 할 방법은 관계형 DBMS를 XML DBMS로 변환하는 방법과 관계형 DBMS와 XML을 접목시키는 방안이 있을 수 있다. 본 연구는 관계형 DBMS에 XML 어댑터의 기능을 적용한 XML DBMS를 설계하였다. 이와 같은 방법의 DBMS를 구축하면, 기존의 관계형 DBMS를 변경하지 않으면서, XML DBMS로의 기능을 수행 할 수 있게 하면, 시스템 구축에도 적은 비용으로 커다란 효과를 얻을 수 있을 것이다.
