The most important technology in the electronic commerce based on Internet is to guarantee the security of trading information exchange. Many technologies are proposed as a standard to support this security problem. One of them is an XML (eXtensible Markup Language). This is used in various applications as the document standard for electronic commerce system. The XML security has become very important topic. In this paper an XML security model for web services based electronic commerce system to guarantee the secure exchange of trading information. To accomplish the security of XML, the differences of XML signature, XML encryption and XML key management scheme respect to the conventional system should be provided. The new architecture is proposed based on unique characteristics of XML. Especially the method to integrate the process management system need to the electronic commerce is proposed.

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.

XML was applied to web-Based application system for efficient data supervision and processing. Also, ASP permitted embodiment of easy web-Based programming, and UML is studied by the new alternative of system modelling techniques. Thus, In this paper see embodied student taking a course application management system using XML, ASP, UML. This was composed, and used XML for effective data supervision and processing by student mode and administrator mode. Also, It used UML for systems analysis and design, and whole system implemented by ASP. And, Database implemented to used in MS-ACCESS, and it used java Script language for efficient practical use of web document.

Systematic management of data related to business process, and information exchange within existing information systems or between different companies have recently become an important issue. This paper tries to solve such problems by using form based workflow system using XML(extensible Markup Language), a standard for digital document exchange. In this system, a new model that formalizes documents into XML form documents and manages them is developed. By defining and operating form documents by XML, information exchange within existing information systems such as ERP and SCM or between different companies, and interoperability between different WFMS can be easily achieved. In addition, by matching form, a formalized document, with existing database schema, WFMS can be directly applied to existing information system, thus enabling continuity of data management and business activity.

The current disaster management manual is being utilized as a book or document-based type. It causes a low applicability and interoperability in practical business because each information has a different document format and it is difficult to recycle those information as common disaster information. The information reading by text type without electronic data and visual object also has a limitations in guaranteeing a quickness of disaster management business. Accordingly, the electronic document management system with visual information is necessary and the system needs to tie framed by XML schema because the electronic document standard will be changed from DTD to XML schema. This study attempts to develop a procedural methodology of an electronic document management system based on XML for disaster management. The applicability of the proposed results is verified by the simulated scenario.

XML is recommended by W3C(World Wide Web) and widely accepted as a standard markup language for expression and sharing data. Recently, increasing the use and the amount of XML documents, there is required that easy methods for accessing XML documents at anytime and anywhere, therefore, the distributed XML repository systems is developed. For this, distributed XML repository systems is necessary to research catalog management schemes. In this paper, we design distributed XML database model considering CPU costs, I/O costs, concurrency control, two-phase commits a protocol, queuing delay and so on. And we implement a simulator in order to execute performance evaluation centralized catalog method, fully replicated catalog method, and partitioned catalog method using reasonably setting up environments.

In restricted resources based on mobile environment, we can use an embedded database technology for management of MPEG-7 data. At this time, some XML clustering methods can be used. But, to improve the performance efficiency better, a new clustering method is need to store effective MPEG-7 document. In this paper, we have designed and implemented a MPEG-7 document management system to store MPEG-7 document effectively in mobile device such as PDA. The system used the 버클리 DB XML as a native embedded XML database system based on the clustering method of MPEG-7 data.

New trends such as electronic commerce, virtual organizations, e-business applications, etc. increase the dependence of production management on information software systems and contribute to the needs for global, distributed object systems. This paper presents a component based approach for production management systems under the multi-tier distributed information system architecture using UML(Unified Modeling Language), CORBA(Common Object Request Broker Architecture) and XML(eXtensible Markup Language) technologies, and propose rules for mapping a UML class diagram to a XML DTD (Document Type Definition). And we adapt it to the prototype system implementation. The components are implemented by CORBA and we use XML messages for the information exchange between components.

One of the important applications for business-to-business electronic commerce is in procurement and inventory management using electronic data interchange(EDI). Using online catalogs and approved supplier lists, firms can easily create requisitions and purchasing documents. The emerging trend in EDI technology is changed from VAN(Value Added Network) based EDI to XML based EDI. This paper intends to suggest a component-based XML/EDI system using Unified Modeling Language(UML), as an application system for automobile part industry. Applying component based XML/EDI systems designed with UML methodology, we analyzed the workflow and the document on procurement process between trading partners and implemented a prototype of efficient XML/EDI system, as a surrogate of existing VAN/EDI. The result of applying object-oriented CBD(Component Based Development) technique is to minimize the risk of life cycle and facilitate the reuse of software as mentioned to limitation of information engineering methodology. It enables the interoperability with corporate legacy systems such as ERP(Enterprise Resource Planning), SCM(Supply Chain Management). This system proposes a solution to apply analysis phase and design phase in implementation of XML/EDI system. The implementation of XML/EDI system using CBD shows the ease of use in software reuse and the interoperability with corporate internal information system. The purchasing department with XML/EDI system can electronically communicate purchase orders, delivery schedules to external suppliers and interoperate with other application systems.
