XML has emerged as the internet standard for information exchange among e-businesses and applications. Therefore, it becomes necessary to store XML documents in database for efficient management. This paper describes the design and implementation of XML documents storage and retrieval system based on object-relational database. The storage method first, decomposes XML document into Element, and then stores according to element types. The system also supports various search methods to retrieve XML documents from database.

Recently, mobile commerce is widely spread around the world according to fast growth of the mobile communication market. The existing digital document is not well fit in mobile commerce because of weakness of the hardware of mobile devices, low bandwidth of wireless communication, and the constraints of the size and resolution of the display. In this paper, we analyzed the elements of the digital document proper for mobile commerce based on wireless communication, designed the XML form for the digital document, and implemented the X-Auth which is an authoring tool for the XML digital document. X-Auth does not require that the author or user know XML. And also it makes it possible to create the digital document fit for the size of the mobile device display and therefore remove inconvenience due to the scrolls.

In this paper, we design and implement practical application service using VoiceXML. And we suggest new solutions of problems can be occurred when implementing a new systems using VoiceXML, based on the fact. Up to now, speech related services were developed using API (Application Program Interface) and programming languages, which methods depend on system architectures. It thus appears that reuse of contents and resource was very difficult. To solve these problems, nowadays, companies develop their applications using VoiceXML. Advantages of using VoiceXML when developing services are as follows. First, we can use web developing technologies and technologies for transmitting web contents. And, we can save labors for low level programming like C language or Assembler language. And we can save labors for managing resources, too. As the result of these advantages, we can reduce developing hours of applications services and we can solve problem of compatibility between systems. But, there's poor grip of actual problems can be occurred when implementing their own services using VoiceXML. To overcome these problems, we implemented interactive stock trading system using VoiceXML and concentrated our effort to find out problems when using VoiceXML. And then, we proposed solutions to these problems and analyzed strong points and weak points of suggested system.

XML은 의미적으로는 동일하거나 혹은 유사하지만 서로 다른 구조의 XML 문서들을 허용하므로 XML 문서들을 대상으로 하는 검색, 클러스터링 등의 응용에서는 XML 문서들간의 유사도 계산이 선행되어져야 한다. XML 문서간 유사도를 계산하기 위해서는 문서의 구조 정보인 엘리먼트들과 이들 엘리먼트들의 계층적 구조가 고려되어져야 한다. 본 연구에서는 두 XML 문서가 얼마나 유사한 경로들을 공통으로 가지냐를 두 문서간의 유사도로 보고, 경로 유사도 계산식과, 이를 기반으로 하는 문서 거리 및 문서 유사도 계산식을 정의하여, 유사도 계산 기법을 제안한다. 제안된 기법과 기존 유사도 계산 기법들을 예제 문서들을 통해 계산결과를 비교한다.

XML has been established as a de facto standard for representing and exchanging documents, and has been widely used as a logical data model. Using XML as a logical database model, it requires a conceptual model for the semantics that XML has. However, the existing conceptual models, such as Entity Relationship models and UML, have been extended their concepts to express the specific characteristics of XML, but so far, there are no standard models. This paper compares the characteristics of the typical model of conceptual model of XML by Extended Entity Relationship model from the perspective of database field. For this, we propose the requirements that must be met for XML, and on the basis of these requirements, the approaches of each model are compared.

The goal of this paper is to develop a production management system based on XML that exclusively applies to a production line of machine-parts. This paper aims to develop the related management modules and integrate them into the production management system based on XML technology. In terms of the implementation of the client/server database module, it develops the GUI application program that supports the communication between the subsystem that controls machine-parts and the server-side database. By developing the RPC emulator, the system remotely executes server module in the client GUI module. By developing the integration control module that integrates the independently executed modules, it controls the production management system that works as a single organic management system and by developing the POP system, it builds the information system of machine-parts performance records. This information system collects performance data through the serial port of the sensor attached to the machine-parts manufacturing machine, analyzes these data and display them in the GUI fashion, and immediately reflects them in production planning. And also it develops production management system based on XML by using XML technology.

Tactical Data Links are standardized radio communication data links for military armed forces and used to transmit and receive data. Because they are the core elements of achieving information superiority in a NCW environment, various kinds of TDL are used by the Korean armed forces. Operating various types of TDL is very helpful in getting more information; however, at the same time, it is hard to integrate and make them co-operate with other TDLs or C4ISR systems. In this paper, we propose a XML based messaging system to make various types of TDL interoperable in a NCW environment. For the messaging system between TDL and C4ISR systems, we define XML message processing interfaces and suggest binary XML for serialization to save transmission loads over constrained military communication bandwidth. Our experiment results show that the TDL message can be transformed into generalized XML data that is interoperable with other TDLs and binary XML serialization, and it saves parsing and transmission time.

A RDB Storage Model based on the Edge-Labeled Graph is suggested for store the XML instance in Relational Databases(RDB). The XML instance being stored is represented by Data Graph based on the Edge-Labeled Graph. Data Path Table, Element, Attribute, and Table Index Table values are extracted. Then Database Schema is defined, and the extracted values are stored using the Mapper. In order to support querry, Repository Model offers the translator translating XQL which is used as query language under XPATH, into SQL. In addition, it creates DBtoXML generator restoring the stored XML instance. As a result, storage relationship between the XML instance and proposed model structure can be expressed in terms of Graph-based Path, and it shows the possibility of easy search of random Element and Attribute information.

If the management through the center server is unnecessary and JXTA is connected to a network, a communication with any kind of devices or some device is possible. And features that a communication with heterogeneous P2P systems is possible have. The important module of the designed Data exchange system an interworking between the P2P system which it is made we used API and the each other different protocol the possible data for replacement Data exchange system were designed this kind of a feature was to the utmost utilized may account for the XML Parser Component(XPC) which we use it parses the or about a request and the generated request, and the structure of the XML Making Component(XMC) which we use in generating the inappropriate a request and response.

EDI는 기업간 표준화된 거래서식을 상호합의된 통신방법을 통해서 교환하는 형태로 기업간 업무의 기반 환경을 제공한다. 전통적인 방식의 EDI는 구현이 복잡하고, VAN을 이용해 문서교환을 하는 등 높은 개발비용과 관련 소프트웨어의 폐쇄성 때문에 확산이 잘 되지 않고 있는 실정이다. 이에 본 논문에서는 웹 기반의 분산객체를 이용하여 신뢰성 있는 XML/EDI 시스템을 설계하고 구현한다. 또, 기존의 EDI 사용자의 데이터베이스와 연동하기 위한 AnySchema라는 컴포넌트를 소개한다. XML/EDI는 VAN을 통하지 않고 인터넷을 이용하기 때문에 웹 브라우저를 사용할 수 있어 EDI 전용 소프트웨어가 필요 없다. 또, 플랫폼에 독립적이고 확장이 용이하며 복잡한 데이터를 처리할 수 있을 뿐만 아니라 이기종간 데이터 교환이 수월한 XML을 이용함으로써 EDI 도입 효과를 얻을 수 있다.
