Study related to a system that saves a n document, and to search is consisting actively and has a lot of cases to have left emphasis in the function that these systems efficiently save a XML document and can search. Also, It has a table or the storage structure which was especially designed in order to save a XML document and can save structure information of a document in addition to contents of a XML document together and can efficiently do content retrieval of a XML document or a structure search with an early base. As for this paper, a design implemented the data which the many different kinds of database that had currently used had with you so that did recycling and shared conversion and this XML file in Web, and output can become a XML format through various interrace.

Electronic commerce that is constructed in existing and XML document that is used in e-Business field made out because based to DTD. However, XML applications that XML Schema is much after become Recommendation in W3C May, 2001 XML Schema real condition that is developed to base be. Selected XML Schema in ebXML Registry 2.0 by representative thing connected with this. If develop XML Schema, compare when develop using existent DTD and complexity by namespace or object-oriented concept etc. was increasing, and could programming by various method. XML Schema document that is used by ebXML Framework in treatise that see hereupon study about XML Schema document editing system that offer mastication and user interface that can edit efficiently do.

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.

XML is the new universal format for structured documents and data on the World Wide Web. As the Web becomes a major means of disseminating and sharing information and as the amount of XML data increases substantially, there are increased needs to manage and design such XML document in a novel yet efficient way. Moreover a demand of XML Schema(W3C XML Schema Spec.) that verifies XML document becomes increasing recently. However, XML Schema has a weak point for design because of its complication despite of various data and abundant expressiveness. Thus, it is difficult to design a complex document reflecting the usability, global and local facility and ability of expansion. This paper shows a simple way of modeling for XML document using a fundamental means for database design, the Entity-Relationship model. The design from the Entity-Relationship model to XML Schema can not be directly on account of discordance between the two models. So we present some algorithms to generate XML Schema from the Entity-Relationship model. The algorithms produce XML Schema codes using a hierarchical view representation. An important objective of this modeling is to preserve XML Schema's object-oriented concepts such as reusability, global and local ability. In addition to, implementation procedure and evaluation of the proposed design method are described.

With the spread of internet, the digitalization and the knowledge informatization are in progress rapidly. Specially, numerous users make the various works and use the services on the web. For the most part, these works make use of the XML The XML shines the reusing of the documents because it is separated from contents and sues. Also, it can re-define the logic structure of the document for requirement of the developer. However, the XML document’s size is much larger than common text document because it handles the document type and adds numerous tags for representing structure of the document. To utilize the limited storage devices of Palmtop, PDA and so u, it is necessary to compress and handle the documents efficiently. Recently, the compression techniques for efficiently handling and compressing the XML documents are under way to solve this problem. But most of the existing researches don't support the query processing for the compressed XML documents. In this paper, we design and implement the XML compression algorithm that compresses the XML document and Processes the query of compressed XML document faster and more efficiently than previous techniques.

The reason of a today business of the biggest change is commercial transaction through Internet. Day relent, the commercial transaction through such Internet is giving B2B company transaction the biggest influence. The Document for information exchange that need to B2B company transaction through Internet must send efficiently the information, independent in the system and improve a Interoperability between business partners. Existing information exchange document happened problems about information exchange and the entry of XML became the gauge to solve problems that had an existing information exchange document. Also, the e-business based on XML was constructed. Thus, writing out necessary document for the as well as XML document. In this paper, 1 designed and implemented of integration document editing system to create document for e- business.

XML is being accepted as a standard for the next generation web documents, as it enables to extend the document structures. However, general users have difficulties in writing valid and well-formed XML documents, since the documents should satisfy the grammatical constraints of XML. In this paper, we present a syntax-directed XML document editor which will ease users in writing valid XML documents. The editor will help users, and increase productivity in writing XML documents.

The current text based XML document systems are editing text and don't perform syntax check. As a result, the validity of an edited XML document can't be decided it is well-formed or valid until it is parsed. This paper describes a design and implementation of the syntax-directed editing system for XML documents. Because this is tree-based system, it is easy to extend XML document. And this system is designed to validate XML documents in real-time, It is expected that this paper contributes XML related application developments.

oping and applying XML techniques. One key aspect of our taxonomy is the support of the credibility of the result by evaluating which XML document types can be processed by a method. Another key aspect is to provide a basis for determining which is the best for target XML document types. Application with preparations for XML document mining shows that our taxonomy may present XML document types to be able to consider during the preparation process and target XML document types to be used for experiments.
