Base on traits of XML and database,the text bat around hold on XML document data import and data export,and implement of function directness edit XML documents.This design show a antetype achievement of data integration tools holding on XML in data warehouse.

基于XML与数据仓库的特点，详细讨论了支持XML文档的数据导入、支持XML文档的数据导出等技术，以及直接对XML文档的编缉等功能实现，给出了支持XML作为中间转换的数据仓库中数据集成工具的原型实现。

First design a reasonable XML Schema structure and under the restriction of XML Schema use XML to describe the UML class diagram and the related specification, and then extract the test specification of method from XML test script. Test specification refers to predicate sequences in the form of conjunctive normal form, extracted from basic constraint conditions of variables included in test scripts and expected outputs. Each conjunctive normal form can be transformed to an inequation set, and adopt 1×1 domain test strategy to every inequation set to produce the domain test matrix, which in turn produce the test case.

首先设计合理的XML Schema结构，并在该XML Schema的有效性约束下，用XML对UML类图及相关性约束进行脚本描述；其次对XML测试脚本进行分析，提取方法的测试规约说明，所谓测试规约说明就是从测试脚本中包含的变量的基本约束条件以及期望输出中抽取得到的以合取范式形式存在的谓词序列；每一合取范式对应一个不等式组，对每一个不等式组采用1×1域测试策略，生成域测试矩阵，最终得到测试用例。

The researches show that with the concepts of relational database extended to XML documents involve further definition of a functional dependence XML XML multi-valued dependencies, and the fourth Normal form of XML Documents (4XNF).

在过去的研究当中，已经有学者将关联式资料库的概念延伸到XML文件当中。进而定义出了XML功能相依性(XML Functional Dependency， XFD)、XML的多值相依性(XML Multi-Valued Dependency， XMVD)，以及XML第四正规化(4 XML Normal Form， 4XNF)。

We consider another important class of XML semantic constraints, XML functional dependencies XML FDs, and then present a method based on the hybrid inlining to map XML to relations for storage in the presence of XML FDs specified over DTDs.

这里，我们着重考虑了XML的另一种语义约束，即XML函数依赖，基于已被前人提出的Hybrid Inlining方法，提出了一种既能保持XML文档内容信息和结构信息，又能保持XML函数依赖信息的映射方法。

From the associated DTD of an XML document, our method can abstract several logical XML element segments called ACS-D's. These ACS-D's then can be used to identify some practical XML element segments, called ACS-X's, from the XML document.

我们的方法先从XML文件附属的DTD中，摘取出干个辑的XML元素片段，叫做ACS-D，然后再用每一个ACS-D从XML文件中辨出符合这个ACS-D结构的干个实际XML资元素片段，叫做ACS-X。

In this thesis, we introduce XML relevant technology and database swapper at first, continue chapter four, chapter five provides display on WEB of XML technology and switch technology of XML to HTML, and then chapter six provides XML application embodiment in the database --The bus inquires about the system online.

在这篇论文中，我们首先介绍XML相关技术与数据库交换技术，接着第四章，第五章给出了XML技术在WEB上的显示及XML到HTML的转换技术，紧接着第六章给出XML在数据库上的应用实例-公交车在线查询系统。

The design includes many new technologies in data exchange and data security, they are: Converting non-XML data to XML in order to apply the XML security technology to more data types; Using the technology of XKMS and PKI to manage the public key in order to overcome the shortage of complexity and difficulty in using PKI and improve the efficiency of the public key management; Using Diffe-Hellman algorithm combining with the public key technology to exchange secret key in order to furthest increase the security of the key; Using the technology of XML digital signature algorithm to ensure the integrity, message authentication and signer authentication of the data; Using the technology of XML encryption to ensure confidentiality of the data; Defining delegable access rules on the structure and content of the XML documents to provide fine-grained access control. According to the XML security framework, a XML security library is designed and implemented.

在对XML及其安全技术主要包括XML加密技术、XML数字签名、公钥管理、密钥产生和交换进行研究的基础上，结合传统密码技术和XML安全技术提出了一种基于XML的数据安全模型，模型中包含了目前网络数据交换和安全领域的一系列最新技术，主要有：将非XML格式数据转换为XML格式数据的方法，以保证现有的大部分网络数据能够应用XML安全技术；使用XML公钥管理技术结合PKI技术管理公钥，以克服PKI技术实施和部署复杂、难度大等问题，提高公钥管理的效率；使用Diffie-Hellman算法结合公钥技术交换密钥，以最大限度保证密钥的安全；使用XML数字签名技术保证数据的完整性、不可否认性和发送方身份认证；使用XML加密技术保证数据的机密性；根据XML文档的内容和结构定义授权访问规则进行良好的访问控制。

Extensible Markup Language ,or XML, is also derived from SGML,,However, unlike HTML,XML uses markup tags to describe the meaning, or semantics, of the text ,rather than its display characteristics, XML offers businesses hope for a common language that they will be able to use to describe products, services, and even business processes to ech other in common, shared databases, XML could help companies dramatically reduce the costs of handling intercompany information flows

可扩展标记语言，或XML ，也是来自SGML的，，但是，不同的HTML ， XML的使用标记来描述标记的含义，或语义，文字，而不是其显示的特点， XML的企业希望提供一个共同的语言他们将能够使用说明的产品，服务，甚至业务流程，舍其他共同语言，共同的数据库， XML的可帮助企业大幅度降低处理公司内部的信息流动的成本

可扩展标识表记标帜说话，或XML ，也是来自SGML的，，可是，分歧的HTML ， XML的利用标识表记标帜来形貌标识表记标帜的寄义，或语义，笔墨，而不是其表现的特点， XML的企业但愿供给一个配合的说话他们将可以或许利用申明的产物，办事，乃至营业流程，舍其他配合说话，配合的数据库， XML的可帮忙企业大幅度低落处置公司内部的信息活动的本钱

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。

This is not an ordinary box, which is used as a background picture of the dialog box, very pretty.

详细说明：这可不是一个一般的对话框，它是用图片作为背景的对话框，非常好看。

Conceal me what I am,and be my aid for such disguise as haply shall become the form of my intent.
