With embedded computing technology makes progress , various applications have been developing in PDA. And information exchanging through U document is underway actively between applications in internet environment. But most of the embedded system has Poor hardware resource. And embedded system uses own file system for XML document management. For reason of, it occurs to many of difficulties of data share and information exchange among other systems. Therefore, an importance of the XML Document Database Management System is on the rise in the embedded system. In this Paper, we design and implement Embedded XML Document Database Management System(EXDMS) for efficiently management of XML document and supporting data sharing and information exchanging through XML document in embedded system. As compared with file system, EXDMS shows results that more excellent performance about expandability and compatibility of application. Also, EXDMS has an excellent data Processing performance in poor system environment.

XML is standard of web document, and is used in language for document data exchange. XML document is used as example that change existing document to XML or makes new document by XML increases and XML search system to search XML document efficiently accordingly is requiring. This paper describes design and implementation of query processing system for translating XML elements and data between XML documents and relational database and consist of XML to DB processor, DB to XML processor and XML document management processor. Through this, described for design and embodiment of efficient XML document search system of JAVA base using XQL that is proposed in language of quality of XML document.

In rapidly changing an information=oriented society, it is essential to control massive document information by electronic file. In relation to these electronic document, it is also important to keep and maintain all kinds of information without any losses. It should be allowed to trace previous contents as well as recently updated contents by controlling updated contents with version. For these, XML is recommendable. In this thesis, we intend to save the document storing space by saving only updated contents with version without saving whole documentation, when document is updated. In case of controlling the history of document update by version, we designed system so as to omit "JOIN operation" if document size is under a certainspecific size. Therefore, we implemented a new XML document repository system which is possible for quick search and efficient XML document saving by reducing perfomance deterioration caused by JOIN operation.

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.

In most organizations, the relational DBMS was used for store and manage XML documents due to the pre-established relational DBMS. But, relational DBMS has some problems. They has the possibilities of informational loses in the process of mapping the structure of XML documents to RDB, and they require expensive cost to reflect all XML properties. Thus, this paper was intended to design and implement XML document management system which utilize O2 DBMS-object oriented DBMS in order to overcome the existing problem and reflect all XML Properties. The XML document management system purposed in this thesis has multiple function, such as the library service function for XML documents-check-in/check-out, versioning, user access management-, dynamic indexing and retrieval, and publishing function using style sheet.

Recently, as the Importance of the management on internet documents has highly increased, the research of an XML repository system has been actively made to store, retrieve and manage large XML documents. The version management for XML documents is required in the XML applications such as patent documents, software design and system manual that the modified documents have to be managed. In this paper, we propose a data model based on a fragmentation model that supports document versioning. We also design and implement an XML repository system supporting document versioning. It is shown through Performance evaluation that our system outperforms the existing repository system.

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.

XML has been proposed as a document standard for the representation and exchange of data on the WWW, and also becoming a standard for the search and reuse of scattered documents. When implementing a XML contents management system, special consideration should be imposed on how to model data and how to store the modelled data for effective and efficient management of the semi-structured data. In this paper, we proposed a new data model for the storage and search of XML document data. This proposed data model could represent both of data and structure views of XML documents, and be applied to the new data system for XML documents as well as the existing data systems.

The Request of the information exchange is increasing because of the advanced rapid science and technology. But a different system environment has occurred many problems on the information exchange. The information exchange on based XML is a solution to the problem. It takes effect in the standard document management application that is make standard document to cooperate with many researchers mutually. This paper is design and implementation of system model for efficient exchange, store, search and manage document on based XML document in established course of standard document.
