EDI(Electronic Data Interchange) works by providing a collection of standard message formats and element dictionary in a simple way for businesses to exchange data via any electronic messaging service. Open-edi is electronic data interchange among autonomous parties using public standards and aiming towards interoperability over time, business sectors, information technology and data types. The number of Internet services using XML/EDI has grown rapidly since it is easily expansible and exchangeable. To use this service, the client does not have to install EDI S/W but only needs internet browser. Consequently, it became much easier and faster to handle the trading process in an office. eBusiness SML (extensible markup language) electronic data interchange. eXedi is the service that realizes B2B of XML/EDI. eXedi can be used easily in small and medium sized companies. Companies in any place can access to eXedi using the existing Internet connection. XML/EDI provides a standard framework to exchange different types of data -- for example, an invoice, healthcare claim, project status -- so that the information be it in a transaction, exchanged via an Application Program Interface (API), web automation, database portal, catalog, a workflow document or message can be searched, decoded, manipulated, and displayed consistently and correctly by first implementing EDI dictionaries and extending our vocabulary via on-line repositories to include our business language, rules and objects.

Presented in the paper is a methodology for the distributed simulation of underwater warfare based on standard synthetic environment. In the case of underwater warfare simulation, it is very important to reflect environmental data, such as salinity and temperature. For the reusability and interoperability of environmental data, this paper adopts Synthetic Environmental Data Representation and Interchange Specification (SEDRIS(ISO standard for environmental data)). Although SEDRIS provides various merits as an international standard, applying of SEDRIS has been hindered by its broadness and heaviness. To relieve the difficulties, this paper proposes an efficient procedure to utilize SEDRIS technology for the atmosphere and underwater environment. This paper identifies SEDRIS structure for the atmosphere/underwater structured dimensional grid-based and implements the proposed procedure on the High Level Architecture (HLA) / Run-Time Infrastructure (RTI) to explain the generation of the battlefield in a distributed simulation system.

These days, a modeling tool or environment has to know about the others on the market and build bridges to them with which their customers insist on sharing models and data. When it is based on a closed architecture, a tangle of import/export point translators is required. Using an exchange standard, we can design an open architecture for the interchange of models and data. XML(Extensible Markup Language) provides a framework for describing the syntax for creating and exchanging data structures. The explosive growth of XML-based business proposals and standards reflects the urgent requirements and its strength. This paper proposes an XML-based language for sharing decision models within the MSOR/DSS community. The language is able to allow applications and on-line analytic processing tools to models obtained from multiple sources without having to deal with individual differences between those sources. It is expected to be a medium for B2B integration by supporting flexible interchange of decision models.

Many companies are using EDI (Electronic Data Interchange) for the electronic transmission of documents and information to and from other companies. The appearance of Internet can enhance existing EDI systems. Existing EDI systems have several problems such as poor system interoperability and high expense of VAN. This paper prognoses a new EDI system utilizing Internet to provide open communication environment by using XML (extensible Markup language) and this applies it to the EDI service for Hospital Demand. XML is a mark-up language extending HTML which is a standard language for the expression of WWW (World-Wide Web) pages. XML is more structural than HTML, thus it is more suitable for the repetitive tasks of EDI and for the maintenance of databases. XML can transmit EDI documents in the open communication environment of Internet and users can easily access the documents with web browsers. Therefore we can provide EDI services within more open environment and we can build an EDI system with lower expense.

Electronic Data Interchange (EDI) has been used for business-to-business communication for almost a quarter of a century. Initial efforts Involved inter-company agreements on how to exchange commercial data, initially as information stored on tape and later as messages sent over dedicated data lines. To avoid having to use different protocols to move data between different companies, various Industry groups identified sets of data that could form the basis of individual agreements. The industry groups also sought to agree the format in which fields in such data sets were interchange so that a company only needed to develop one methodology for decoding information received without resource to human intervention. The XML/EDI specific components are built on top of existing standards for transmitting and processing XML-encoded data. These standards define shared features such as: the standard Internet file storage/naming and data transport mechanisms, file and message transfer formats, the syntax of data coded in XML, the way in which XML files can be validated by an XML parser or document object model generator, the way in which XSL presentation and data evaluation scripts can be associated with parsed objects, the use of rules and data management robots to manage application and repository interfaces.

Metadata is data about data that is used to mange data itself. As applications based on DBMS are increased, it is suggested that metadata model and metadata interchange model to manage metadata in DBMS. but metadata which is in the form of XML (eXtensible Markup Language) document is generally stored into RDBMS. Therefore In this paper, as for the method to store metadata of RDBMS into OODBMS, we design metadata model, metadata interchange model and implement new repository system. The metadata of RDBMS is translated into in the form of XML Document and integrated into XML Data Server on OODBMS, eXcelon and executes retrieval metadata information about RDBMS by XQL(XML Query Language). So It is possible to searchm edit a metadata. The metadata of XML documents stored in eXcelon is easily made to be printed in web browser by applying a XSL (extensible StyleSheets Language). So we can have a detail information about property of metadata in DBMS.
