At present many commercial database using Xpath and XQuery as XML retrieval standard, grammar about XPath and XQuery is complicated , it is difficult for general user to use. In this paper, the research work is focused on the keyword retrieval technology of XML document, designs a XML full-text information retrieval similar to HTML full-text information retrieval,proposes inverted-file retrieval method...
In this paper, we report ongoing research on what we call locally complete XML databases. These data banks consist of an XML data tree together with a specification of the nodes of the tree that are completely represented in the document. The specification of completeness is defined by means of the defacto standard node selection language for XML, XPath, which makes this approach easy to implement...
Real-world databases often have extremely complex schemas. With thousands of entity types and relationships, each with a hundred or so attributes, it is extremely difficult for new users to explore the data and formulate queries. Schema free query interfaces (SFQIs) address this problem by allowing users with no knowledge of the schema to submit queries. We postulate that SFQIs should deliver the...
Due to the growing use of XML data format in global information, an effective XML data management system is needed. An Enabled XML DB is one of the recent widely accepted approaches to store XML documents. This ability coupled with the increase use of XML data in different areas have triggered the need for a better method to structure a large data in order to improve query performance. Issues concerning...
The huge data requirements of large nowadays applications in science and engineering make optimised and scalable data placement mechanisms an essential need. For this purpose, we propose a scheduling scheme based on an efficient data locality management for data-intensive workflows. Transfer and placement decisions are made based on constructions in the workflow, representing inter-relationships between...
On the Web, the use of online forms to gather user input is constantly increasing. To simplify the task of generating and handling such forms, we propose the creation of a database describing the layout and content of such forms. In this paper, tables describing form data are defined, and constraints among the attributes of each are discussed to avoid form errors. In addition, the types of errors...
Presently, there are still many problems on acquiring patent information from the Website ,we can't acquire a large number of information efficiently and accurately. In this paper, use the two-tiered scheduling Multi-Agent to design the patent information acquisition system. The process of acquisition patent information from United States Patent and Trademark Office (USPTO) web database which includes...
Nowadays XML have reached a great interest, because it is possible to share information through the Web. Moreover, the Web can be conceived as a huge Database. Therefore, like DBMS traditional, the Web needs efficient algorithms to detect changes on the Database. In this paper we present an efficient algorithm to detect change in XML documents. Algorithm efficiency resides in the efficient application...
This paper made an in-depth research on information resources and personalized service and research status of system implementation techniques, combined with the practical work of graduate design, the use of Ajax, database, network communication and ASP.NET and other technologies on information resources and personalized service system's overall architecture was design. The system uses a hierarchical...
The features and application ranges of several database design proposals applied in SaaS are discussed. Based on shared database / shared framework, three relationship-based extension models which are custom field, pre-allocation field and name-value pairs and XML-based extension model are discussed and the latter implementation approach in data definition, query and update is also given, along with...
The increasing variety of data mining tools offers a large palette of types and representation formats for predictive models. Managing the models becomes then a big challenge, as well as reusing the models and keeping the consistency of model and data repositories because of the lack of an agreed representation across the models. The flexibility of XML representation makes it easier to provide solutions...
For the existing shortcomings in current XML document query optimization technology, this paper presents an efficient query optimization method based on view. The method can quickly and efficiently find an effective view, thus to greatly improve the speed of query and better achieve the XML document query optimization. And then it designs a XML document processing system, and through experimental...
Using structured data formats like XML in wireless sensor networks to support exchangeability and heterogeneity on application level has become an important research topic in the area of large scale networked sensing systems. Besides, the usage of XML encourages the adaptation of service oriented programming techniques to simplify sensor network application engineering. While the sensor nodes still...
Mass for the current space-time multi-source heterogeneous data in the organization, management, integration difficulties, for traditional methods in the data conversion process and other issues caused data loss, Combining the characteristics of ocean space-time data, This paper presents a new seamless integration of massive multi-source heterogeneous space-time data technology (SIMMHS).The technology...
In this paper, we discuss the architecture of a system, the so-called Web and Document Databases (WDDBS for short), designed to explore the Internet effectively and efficiently. Abstractly, a WDDBS can be defined as a triple <;D, P, W>, where (1) D stands for a local document database to store XML documents, (2) P for a subsystem responsible for remote query evaluation, including resolution...
The difficult issue of Web data mining is proposed to achieve Web data mining method, which is based on XML-based Web database in the face of semi-structured data structure excavation process, the data feature extraction process, we found the hidden rules and knowledge, the method is simple, effective and low cost. The paper first gives the definition of data mining; describes the process and commonly...
Fuzzy logic reflects human nature to express and evaluate the world in a vague manner. This paper describes our approach to incorporate fuzzy logic into XML database systems. The system was built on top of traditional XML databases, while allows the storage of fuzzy data as well as crisp data. The paper describes the structure of the system, starting with the critical architectural component named...
EHR (Electronic Health Records) describing the diseases and treatments of patients are normally stored in the hospital locations or regions, where they are created. However, patients may be treated in different hospitals, and, therefore, there is a need for integrating health records from different hospitals to enable any hospital to obtain a total overview of a patient's health-history. Two different...
Reporting Tool is one of the most prevalent applications in diversified fields. Most of the available commercial reporting tools often provide overabundant functions with complicated operating procedures, while users emphasis on ease of use and generation efficiency. Accordingly, we are presenting a pattern-directed design mode, in which a report can be designed by recombining reusable report elements...
