In this paper, we design and implement a XML management system based on OODBMS that supports structured information retrieval of XML documents. We also propose an object oriented modeling to store and fetch XML documents, to manage image data, and to support versioning for the XML document management system(XMS). The XMS consists of a repository manager that maintains the interfaces for external application programs, a XML instance storage manager that stores XML documents in the database, a XML instance manager that fetches XML documents stored in the database, a XML index manager that creates index for the structure information and the contents of documents, and a query processor that processes various queries.

With the explosion of bioinformatics data such proteins and genes, biologists need a integrated system to analyze and organize large datasets that interact with heterogeneous types of biological data. In this paper, we propose a integration system based on a mediated data warehouse architecture using a XML model in order to combine protein related data at biology laboratories. A fact constellation model in this system is used at a common model for integration and an integrated schema it translated to a XML schema. In addition, to track source changes and provenance of data in an integrated database employ incremental update and management of sequence version. This paper shows modeling of integration for protein structures, sequences and classification of structures using the proposed system.

B2B 전자상거래와 같이 XML을 이용한 정보교환이 확산되고 있으며 이에 따라 상호 교환되는 정보에 대하여 체계적이며 안정적인 저장관리가 요구되고 있다. 이를 위해 XML 응용과 데이터베이스 연계를 위한 다양한 연구가 관계형 데이터베이스를 중심으로 수행되었다. 그러나 계층구조를 갖는 XML 데이터를 2차원 테이블의 집합인 관계형 정보로 표현하는 관계형 데이터베이스로의 저장에는 본질적인 한계가 있어, 계층구조를 지원하는 객체지향 데이터베이스로의 저장이 요망된다. 따라서 계층구조를 갖는 XML 데이터를 객체지향 데이터베이스로 저장하기 위한 모델링 방안이 요구된다. 본 논문에서는 UML을 이용한 객체지향 데이터베이스 기반의 XML 응용을 위한 통합 설계 방법론을 제안한다. 이를 위하여 먼저 UML을 이용하여 W3C XML Schema를 설계하기 위한 XML 모델링 방안을 제시하고, 아울러 교환되는 XML 데이터를 효율적으로 저장하기 위하여 객체지향 데이터베이스 스키마 설계를 위한 데이터 모델링 방법을 제안한다.

XML(eXtensible Markup Language) 프로그램이나 XML을 이용한 B2B 시스템 구축과 같은 XML 프로젝트에서는 객체 지향적 설계언어인 UML을 이용해 개발하면 효율을 높일 수 있다. UHL(Unified Modeling Language)로 XML문서 구조를 표현하는 이유는 XML문서를 생성, 접근, 수정하는 XML프로그램을 체계적이고 효율적으로 설계할 수 있기 때문이다. DTD(Document Type Declaration)와 스키마(Schema)를 UML로 표현함으로써 프로그래밍을 통합적으로 추진 할 수 있다. 이러한 과정에서 XML의 문서 구조정보의 활용 증대와 UML의 확장이라는 이점을 취할 수 있다. 본 논문에서는 UIML 기반의 다이어그램에서 XML 문서서로의 변환기에 대한 모델을 제안한다.

We can travel every imaginary world and do every impossible thing via 3D character. People interest in 3D character animation for modeling like real world due to the increase of 3D game and imaginary Virtual Reality on the internet. In this paper, new framework for present of 3D character of high quality is applied. I represent 3-dimensional Humanoid modeling and animation technology and show the adequacy via simulation for various and natural representation certificate using VRML as a Web3D information type and XML.

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.

XML is a standard markup language for exchange and storage of formed or well-formed information in World Wide Web, Because the source data of XML message for exchange of information in World Woo Web Is stored in legacy database systems. it is necessary the easier connection between XML application and database systems, In Oracle8i. 9i. informix and SQL2000. DBMS vendors extend their DBMSs for XML. This approach for the connection between XML application and database system is Platform-dependent and DBMS-dependent. Therefore it is necessary the platform- and DBMS-independent approach for the connection between XML application and database system, In this paper. we modeled a set of middleware components for relational database design based on XML DTD is modeled, Those components are modeled on object-based algorithm for connection between XML application and database system.

With the rapid development of computer technology and ongoing destruction of traditional buildings, more and more attention is paid to digital methods for the design and preservation of traditional buildings. Unlike 2D methods, Building Information Modeling (BIM) provides an object-oriented and parametric digital representation way for traditional building components. However, one of the main limitations currently is that parametric information cannot be exchanged between BIM software packages. Therefore each kind of software must have their own parametric library which causes extensive works. In this research, the authors developed an open BIM-based library using an XML parametric approach to solve the above problems, represented traditional components according to an XML schema, and parametrically implemented these XML files in a browser which can be accessed by users for their easy component edit and selection. And then based on the XML file of one component, implemented an Add-on in ArchiCAD for users to parametrically edit and directly utilize. Thus based on these XML files, a browser for users' view and selection purpose and an add-on for users' application purpose were developed. Future research will focus on implementing these XML files in other BIM tools like Revit and Digital Project. If the whole library was to be completed based on this XML approach, an open BIM-based library would be established that all kinds of BIM software users could apply this parametric library for easy modeling of traditional houses.

Information integration for distributed and heterogeneous data sources is still an open challenging, and schema matching is critical in this process. This paper presents and approach to automatic elements matching between XML application schemas using similarity measure and relaxation labeling. The semantic modeling of XML application schema has also been presented. The similarity measure method considers element categories and their properties. In an effort to achieve an optimal matching, contextual constraints are used in the relaxation labeling method. Based on the semantic modeling of XML application schemas, the compatible constraint coefficients are devised in terms of the structures and semantic relationships as defined in the semantic model. To examine the effectiveness of the proposed methods, an algorithm for XML schema matching has been developed, and corresponding computational experiments show changes of calculated values.
