XML has already been the standard of data interchange on the Internet. Nowadays, a large amount of data is represented in XML format. However, most of the critical data in businesses are still stored in relational database management systems. It is difficult to query XML databases because of its textual format. This research intends to tackle this problem, and we proposed a system to manage XML documents that could be queried by the query language XQuery. XML documents are stored in relational format and the XQuery expressions are translated into appropriate SQL queries. The results of the SQL queries are transformed into XML documents. Comparing with LegoDB System, our system reduces processing time to search a relation configuration and proposes a better translating and executing technique which is more efficiently.

The key to achieve the XML query language lies in creating valid XML algebra system. Most of the existing solutions for XML algebra system are an extension of the nested relational algebra and the major difficulty is that the computational complexity of the nested model - instance binding is too great to be effectively solved. This paper proposes an algorithm of XML algebraic system based on the distributed open computing model and then demonstrates its effectiveness in detail. By decomposing the binding process of query mode in the instance graph, this paper utilizes the message delivery to assemble the resulting tree and improve the overall computing performance. Therefore, it can provide effective support for the massive information integration and service system with the distributed open computing environment.

In information retrieval, the user cognitive factors on the search process and results have the significant influence. First of all, the user cognitive factors are reasonably acquired and expressed, and then the technology of XML is applied to faceted recommend. Finally, according to the XML key technical characteristics that in the result shows, different cognitive styles and space ability have different display format. To effectively improve the XML retrieval efficiency and customer satisfaction, the methods not only have the certain reference value, and also have important practical significance.

In homogeneous or heterogeneous databases, the main direction of research on XML-based information interaction between databases is taking XML as middleware to realize the information exchange between data in the environment of small and medium-sized databases. Considering the insufficiency of the traditional text file-based information interaction method, the paper puts forward an XML-based method of information exchanging between databases, and the corresponding database exchanging system is developed. The utmost feature and advantage of the system is taking hibernate XML mapping table file for converting middleware to realize information interaction between databases. The experiment result shows that the system provides a certain reference value for data mining and data warehouse.

Along with the increase of XML applications, Native XML database technology is gaining the attention of the field of database, and query optimization is still one of the key research contents.

XML is widely used nearly everywhere in modern information technology. However, traditional XML semantic constraints expression and validation is still an open issue since grammar-based or rule-based schema languages have built-in limitations in some syntax constraints expression, and the combined ones with more than two languages to check a XML putting a considerable burden on users. A domain-oriented XML expression and validation approach is proposed, which takes high level business concepts to capture the advanced XML constraints in a compact and easy understand way. Some implementation techniques and advantages are also demonstrated to show the lightweight and pragmatic of this approach.

A confidentiality system generally needs to operate under a non-network environment. Hence, the adoption of an offline model is necessary to realize data sharing. An offline data-sharing model based on encrypted Extensible Markup Language (XML) files is designed. The combination of various techniques, such as XML mode, XML encryption, and XML signature, and the introduction of the Security Solution Support Center enable the proposed model to achieve a safe point-to-point data interactive mode and a security-based software module. The software system based on this model can ensure that data files generated from the data provider could only be identified and verified by the authorized data receiver.

Distributed simulation refers to the execution of a complex model on geographically dispersed simulators, and it can increase the speed of a simulation and eventually decrease the simulation execution time. The distributed simulation enables models to be executed in physically distributed position. The system entity structure (SES) is used to represent the structural relation of simulation models and there are several SES’s XML representation methods. To make use of the SES in a distributed simulation environment, the revision of existing XML representation is needed. In this paper, we propose revised XML representation for loading models dynamically in the distributed simulation environment. A template of XML representation is defined to meet a number of modeling requirements, and it shows the specific information of model’s hierarchy and coupling. Each simulator’s model loader analyzes the XML-based SES representations and loads information of a model dynamically. We validate our method using a coupled model example.

Heterogeneous data sharing is always a bottleneck problem for the development of collaborative design. The method of STEP/XML element mapping achieves the data transformation between STEP and XML by establishing the mapping relationship of the two data. It’s hard to ensure all element mapping one to one and easy to cause the partial data loss. Based on the research, this paper put forward a new method with data encapsulation. It encapsulates the whole STEP data into the XML data by using of the XML character data, and then the data are uploaded to the collaborative design platform. Another designer can download it and get the original STEP data by using the XML parser. This method is not only easy to be realized, but also can ensure the integrity of the product model data conversion. It is more conducive to achieve collaborative design.

Web data mining is a field that has gained popularity in the recent time with the advancement in web mining technologies. Web data mining is the extraction of data on web. The term Web Data Mining is a technique used to crawl through various web resources to collect required information, which enables an individual or a company to promote business, understanding marketing dynamics, new promotions floating on the Internet, etc. The data on web is unstructured, irregular and lacks a fixed unified pattern as it is presented in HTML format that represents data in the presentation format and is unable to handle semi-structured or unstructured data . These difficulties lead to the emergence of XML based web data mining. XML was created so that richly structured documents could be used over the web.XML provides a standard for the data exchange and data storage .This paper presents a web data mining model based on XML. In this model first of all unstructured data is transformed to XML and then XML document is stored in database in the form of the string tree, then specific records are searched using a LINQ query. If record does not exist in the database then check the updates of specific website and repeat the same steps. At last data selected by LINQ Query is displayed on web browser. The feature that helped to increase the speed of data extraction and that also reduces the time of extraction is the presence of database that stores the data that have been extracted earlier by a user and can be used by other users by passing a LINQ query .In this model there is no need to create an extra separate XSL file because this model stores xml document in the database in the form of the string tree. This model is implemented using C# with XML.

For solving logical implication problem in the presence of XML strong multi-valued dependency(denoted as XSMVD) and XML weak multi-valued dependency(denoted as XWMVD) under incomplete information circumstances, the inference rules of XSMVD and XWMVD based on XML Schema were discussed. The concepts of XML Schema and incomplete XML document tree according with XML Schema were formalized. Based on the concepts of sub-tree information equivalence and sub-tree information consistent, the definitions of XSMVD and XWMVD were given and their nature was studied. When XSMVD and XWMVD exist at the same time in XML Schema, their inference rules were presented and their soundness was proved. The production in this work lays the foundation for normalization of XML Schema existing XSMVD and XWMVD at the same time under incomplete information circumstances.

This document explains and demonstrates on the Normalization for Internet computing and Modeling of Conceptual Model XML-based. The existing XML conceptual models have their limitation, largely because the semantic, such as “containment” and “multiple-scope”, could not be sufficiently described. XUML is a XML conceptual model based on UML. It is independent of specific XML schema definition language, and puts emphasis on describing relationships between domain concepts and defining related semantic constrains. XML normalization theory is recently a research focus, but the existing research outcomes are very complex so they are hard to be understood by XML designers. The development of database design methodology reveals that it is more effective to apply normalization theory in conceptual design than that in logical design. By following the successful approach, the characteristics of XML normal form are represented in XUML. Several XUML forms are defined, and the normalization based on XUML is investigated. The research on XML normalization theory further enhances XUML methodology. So we show the process of XML normalization in XML conceptual model in the paper. And several normalization methods are introduced. Finally, an example is presented to explain the general application of XML normalization methods.

A multi-polices access control model is proposed, with the model, access control based on policy regulation and XML based policy description is given. At the same time, We use the XSD(XML Schema Definition) to describe the content and the structure of the xml documents, and check the validity of the xml documents. Based on the description of the access control, an application system is realized we construct the runtime platform and choose some access control polices to test our system. The result is well.
