Lately, electronic commerce through the Internet has been rising in attention. An important element in such commerce is EDI. EDI is mainly used with VAN but its use is not common due to the high cost of EDI transfer. Thus, only large corporations with frequent use of EDI are able U benefit from it, To smaller companies that have small usage, EDI is becoming a burden. Considering this fact as well as current changes within the enterprise environment, it is apparent that a new generation of EDI is required. To resolve the problems of VAN EDI, the proposed Internal EDI was implemented. Internet EDI deals with the use of the widely spread Internet instead of VAN. By using Internet EDI, it is possible to reduce the high cost that came when using VAN. There would be no extra transfer cost since transmission will be done through the Internet. Also, electronic commerce that is mostly used today between an individual and a company may grow to become a true electronic commerce between companies.

Internet-based EDI is emerging as a prominent substitute technology for traditional VAN-based EDI technology. The strength of this new technology is based on the explosive growth of Internet community, low "fixed-rate" Internet expense and "globally" open base of its participants. These strengths of Internet-baed EDI bring vast new opportunities for enterprises and thus. have as much implications for IT managers. However, Internet-based EDI technology has, at least by now, several drawbacks too. Most of these drawbacks also comes from the fact that it has its structural base on the Internet. Managers should carefully consider these drawbacks and hidden costs before adopting or switching to this attractive new technology. This presentation attempts to address major trends of Internet-based EDI and its implementation, opportunities and threats of the changes in technology, factors to consider in adopting this technology, and several managerial and strategic tradeoffs and implications of Internet-based EDI for IT managers.

As the Internet spreads rapidly, the industrial structure is changing to a new paradigm. The previous EDI system was asked to be changed and WEB EDI, E-Mail EDI, FTP EDI etc. based on the internet have appeared. Recently, the XML/EDI which is based on XML documents has appeared. EDI system has to assure a safe exchange between senders and receivers. But, the internet has security problems because it uses a open TCP/IP protocol. In this paper, we will propose an XML/EDI system with XML Signature.

As Internet spreads rapidly, the industrial structure is changing to a new paradigm. The previous EDI system was asked to change and WEB EDI, E-Mail EDI, FTP EDI etc. which are based on the internet appeared. These days the XML/EDI which has XML document appeared. The XML/EDI consider advantages and disadvantages of VAN/EDI and EDI which based on the internet. Also, EDI system has to assure a safe exchange between sender and receiver. But, the internet has security problems because it uses a open TCP/IP protocol. Although there are many methods for security, it is being studied with XML concept. On this paper, we will suppose the XML/EDI system model with XML Signature, and build a procedure of electronic signature and delivery of document between sender and receiver.

The implementation of Internet based on EDI has become a major issue because of the huge development of the internet. Internet EDI is a technology which combines the strength of EDI and Internet technologies and it can be classified in FTP-EDI, SMTP/MINE EDI, and Web EDI. Recently, the number of companies which are adopted Web EDI increase to overcome shortcomings of high communication costs and high foundation and maintenance expenses of VAN EDI. This research is intended to examine the effect that characteristics of innovation and partnership as relationship with trading partner will affect the Web-EDI implementation. To achieve these purposes, we surveyed people who are in charge of Web EDI in their companies. A survey questionnaire was sent 376 people in charge of Web EDI in their companies, and 66 usable responses were obtained. The results of this research can be summarized as follows. First, it's affirmed, among partnership factors, that participation and interdependence significantly affect Web EDI implementation. It's also suggested, among innovation factors, compatibility, relative advantage, and cost reduction significantly affect Web EDI implementation.

The importance of EDI has been so emphasized that we need exchange/maintain electronic documents effectively, and convert them to other formats. The traditional EDI, however, is facing on the limitation of growth because of its high expense, and the closeness of information sharing. The EDIs of next generation, like open EDI, object-oriented EDI, and Internet EDI, have appeared to solve these problems. Finally, XML/EDI, which is very effective to solve these kinds of problems, is now replacing the traditional EDI and the HTML in Internet and, is influencing on e-Business. So, we are going to suggest a solution which uses XML/EDI as a substitute for the traditional one. First, we analyzed the problems of the traditional EDI system and organized the structure of XML/EDI system, Next, we developed the prototype of Internet bookstore to show the effectiveness and strength of XML/EDI over the traditional EDI.

Korean government and companies have given a lot of their efforts to exchange electronic documents between themselves and their partners. As the results of them. Korean EDI standards were made by Korean EDIFACT Committee and the standards have been used by companies and governmental organization in Korea. However, Korean export customs clearance EDI system is based on VAN(Value Added Network) and one VAN company ha monopolistic right to relay EDI documents to Korean Customs Service. Therefor is leads to a lot of problems such as inconvenient software, expensive transmission fee and the difficulty of connection with the in-house systems of user companies. To solve these problems, a few good solutions and systems have been suggested and one of them is the Internet EDI. we will suggest a new export customs clearance EDI system running on the Web. This system is basically an Internet EDI system, but we have developed this system using XML instead of HTML, XML is a new markup language with merit such as isolating data from style of documents. This system consists of 7 modules, schema/style/template management, XML/EDI document management, XML/EDI transformation, EDI transmission, certification management and log management. Also this system can be used with other traditional EDI systems that have UN/EDIFACT standards. We will discuss the advantages and disadvantages of XML/EDI system for customs clearance. The development of this system will be a leading study for XML/EDI standards in export clearance EDI system.

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.
