Due to the evolution of computer systems and the proliferation of Internet, numerous information resources have been constructed. The deluge of information makes the need to integrate information, which are distributed on the internet and are handled in heterogeneous systems. Recently, most of the XML -based information integration systems use XML DTD(Document Type Definition) for describing integrated global schema. However, DTD has some limitations in modeling local information resources such as datatypes. Although W3C's XML Schema is more flexible and powerful than XML DTD in specifying integrated global schema, it has more complex problems in resolving conflicts than using DTD. In this paper, we provide a taxonomy of conflict problems in integration information resources using XML Schema, and propose conflict resolution mechanism using XQuery.

XML is suitable to integrate various forms of engineering design data since it possesses the characteristics of both documents and data. In this research a web-based design system has been developed, which integrates various gear design data in the form of XML. The system generates XML document containing gear design data and transforms gear design data in the relational database into XML document form automatically. The XML documents are transmitted to gear modeler agent through SOAP, and then the agent is automatically executed and generates CAD model files and VRML files. The designer can check the generated VRML model of gear immediately in the web service.

XML (extensible Markup Language) is selected and published as a representative standard of electronic documents by W3C (World Wide Web Consortium). The structured information can be created and also transferred in XML documents. By utilizing XML, you can express the meaningful information unit as a structure comparing existed file typed information. With structured information, you can also manage retrieve, and reposit documents. According to the above facts, in this paper, it is the purpose to design and implement XML documents repository system to reposit and retrieve using structured information of XML documents. As a model it was designed to be stored by element unit which is the basic unit of documents and was also designed to retrieve the stored XML information by structured unit. It was, especially, designed to manage and reposit the structure of various documents effectively through creating schema as to DTD(Document Type Definition) and instance.

XML is becoming a de facto standard for the representation and exchange of data, and XML itself is well structured to store and manage data, but it is difficult to understand the document structure at a glance due to its diverse and complex expressions. Thus, it is not appropriate to use it as a tool of conceptual model. In this paper, we propose a method to transform XML schema document structure into conceptual model. To do this, we describe CMXML as a conceptual modeling tool and present transformation rules and data structures for transforming an XML schema structure into CMXML diagram. In the transformation procedure, the XML schema document is input and the CMXML diagram is generated by applying the transformation rules.

In these days, Entity-Relationship Model is the most popular modeling tool for designing databases, and XML is a de facto standard language for representing and exchanging data. But, because of many commercial products supporting Entity-Relationship Model use their's own representation formats, and thus it gives rise to difficulties the inter-operability between these products. In this paper, we propose an ERX, a generation tool of XML Schema from Entity-Relationship Model. ERX receives an Entity-Relationship Diagram as an input, transforms it based on transformation rules, and generates a XML Schema Definition as an output. Transformation rules contain entity set, relationship set, mapping cardinalities, and generalization.

XML은 모든 분야의 데이터를 저장하고 다른 형태의 데이터로 변화될 수 있는 강한 힘을 지니고 있다. 웹에서의 가상 교육에 대한 데이터도 XML로 저장한다면 한번 저장된 데이터는 어떤 사이트에서든 조금의 수정없이 바로 사용할 수 있다. 물론 이 데이터 구조가 미리 정의되어 모든 사이트에서 이 구조대로 XML 데이터를 만들어야 가능하다. 현재 사이버 교육 사이트들의 강좌 데이터는 데이터베이스에, 데이터베이스에서 데이터를 가져오는 것은 ASP, 가져온 데이터를 사용자에게 서비스하는 최종 산출물은 HTML로 구성되어 있어 이 데이터는 더 이상 가공을 할 수 없게 된다. 즉 각각의 사이버 교육 사이트들의 데이터는 서로 공유될 수 없다. 본 논문은 현재 사이버스쿨의 한계를 벗어날 수 있도록 새로운 표준으로 제안되어진 XML을 이용하여 사이버 강좌 관리시스템을 위한 통일된 XML 데이터 구조를 정의하고 웹에서 어떻게 사용해야 하는지 모델을 제시하였다.

XML documents which are used for exchanging structured documents between heterogeneous distributed system are increasing recently. It needs an object-oriented visualization tool for XML documents. So, we propose rules and an algorithm to represent structure of XML documents using UML Class Diagram. It helps to generate XML documents which are included links by understanding easily constructs of them and reduce gap of schema for them between heterogeneous databases. We propose formal models and modeling functions of XML links which provide an efficient environment for processing object-oriented documents.

Software development creates many product that class components, Class Diagram, form, object, and design pattern. So this Paper suggests Index/XML Sequence Relation information system for product abstraction and classification, the system of design product Sequence Relation abstraction which can store, reuse design patterns in the meta modeling database with pattern Relation information. This is Index/XML Sequence Relation system which can easily change various relation information of product for product abstraction and classification. This system designed to extract and classify design pattern efficiently and then functional indexing, sequence base indexing for standard pattern, code indexing to change pattern into code and grouping by Index-ID code, and its role information can apply by structural extraction and design pattern indexing process. and it has managed various products, class item, diagram, forms, components and design pattern.

It is appropriate to use the NETCONF to monitor and manage today's complex networks that are composed of variety links and heterogeneous equipment. Since the first standard of the NETCONF are launched, there have been several revisions, but disadvantages of each layer capabilities is still present and the most typical disadvantage is XML document processing efficiency of the Content layer. In this paper, we perform data modeling by constructing a sub-tree based on the dependencies between Content layer data, and suggest method of extract efficiently data from XML by applying the extended VTD-XML technique for the XPath query. We performs experiment to compare NETCONF in proposed method to NETCONF in previous studies and NETCONF standard. we validate superiority of improved NETCONF in the paper. As experimental results, we verify that improved NETCONF is better than the other two NETCONF each 4% and 10% in terms of query processing rate, and faster than each 3.9 seconds and 10.4 seconds in terms of query processing speed.

This paper presents a 3-D graphic database system based on XML that supports content-based retrievals of 3-D images, Most of graphics application systems are currently centered around the processing of 2-D images and research works on 3-D graphics are mainly concerned about the visualization aspects of 3-D image. They do not support the semantic modeling of 3-D objects and their spatial relations. In our data model, 3-D images are represented as compositions of 3-D graphic objects with associated spatial relations. Complex 3-D objects are mode]ed using a set of primitive 3-D objects rather than the lines and polygons that are found in traditional graphic systems. This model supports content-based retrievals of scenes containing a particular object or those satisfying certain spatial relations among the objects contained in them. 3-D images are stored in the database as XML documents using 3DGML DTD that are developed for modeling 3-D graphic data. Finally, this paper describes some examples of query executed in our Web-based prototype database system.
