In this paper, based on the research of the existing heterogeneous database integration systems, according to the data exchange and sharing needs of enterprise heterogeneous databases, a framework for heterogeneous database integration system is proposed and designed, and the key technologies of the system implementation process are also described in detail. The system provides a heterogeneous data...
The sudden leakage of dangerous chemicals emergency decision system can help the government, chemical accident emergency rescue center, fire fighting and the units of production, transportation, storage or use for dangerous chemicals generate maneuverable emergency rescue plan in the shortest time according to the geographical location and the specific situation of the accident. The system owns the...
Towards the sharing problem of telemedicine data in our country, this paper research an exchange platform of multi-format data based on CDA(clinical document architecture). It adopts Oracle XML DB to store and manage CDA documents, use Web Service to design medical data exchange interface. The platform can effectively solve a variety of formats for data sharing of telemedicine problems.
The integrated Rule Orientated Data System (iRODS) is a Grid data management system that organizes distributed data and their metadata. A Rule Engine allows a flexible definition of data storage, data access and data processing. This paper presents scenarios implemented in a benchmark tool to measure the performance of an iRODS environment as well as results of measurements with large datasets. The...
Chinese electronic government (E-Government) has achieved great success in several years, to quicken the pace of building E-Government, the central government of China has programmed to establish four governance information resource databases in next five years, data center construction in the developed cities is becoming an important project for present China' s E-Government. According to experiences...
Most of the farming devices produce massive amounts of data. In most of the cases, it is necessary to store this data at a central location for further processing. Due to the huge volumes of data, strategies for data aggregation procedures are very important, in order to avoid oversized data sets. There is also an increasing need to share or exchange data with other stack holders in the farming business...
XML has become the preferred format for representing and exchanging structured and semi-structured data on the Web. The XML Schema language is widely used for defining and validating highly structured XML instance documents. While text-based languages, such as XML-Schema, offer great advantages for data interchange on the Internet, graphical modeling languages are widely accepted as a more visually...
During recent years, RFID technology raises many privacy and security concerns. However, most previous works provided authentication protocols by the assumption of secure channel between the reader and the database. But this assumption is not suitable for wireless environment. In 2005, Yang et al. proposed a scheme in which the channel between the reader and the database is assumed to be insecure...
The paper present a specific approach and the corresponding appropriate tools to ensure automated exchange between information systems with databases and different devices with serial communication, non-compliant according to advanced inter-communication standards. In this way, is possible to integrate these devices into information flows and systems. The specific configurations are XML-coded. A complete...
XML (extensible markup language) has become the standard of data representation and data exchange in the Internet. A highly efficient management on XML documents has become an urgent problem. In this paper, we introduce the development of a native XML database management system, called dasiaXSQSpsila (XML storage and query system), which provides the ability of the storage and query for XML documents...
There are some problems existing in present containers management such as idle containers, slow velocity of turnover of containers, disordered containers management, and undeveloped information communication. Our containers management includes three main aspects: tracing management of the containers?? scheduling, allocation, distribution and using during transportation; Tracking record of the containers...
The E-Government System is composed of three networks and one database. The business network within government offices (the Internal Net), the resource network in central and local administrations and departments (the External Net), the public information network (PIN) relying on the Internet. It is necessary to rebuild data in the three networks of the system in order to construct an effective electronic...
Due to the frequent information exchange, electronic mail system is not only a mail exchange platform but also becomes an information center. Users usually save their mails permanently in mailboxes and retrieve them as need. In the database strategy, each mail is separated into several components and stored in the database individually. Whenever a user queries a specific mail, the mail server retrieves...
This paper analyze the structure and network security strategy as well as expounding the key technologies and methods based on characteristics of small town's e-government system. Its discuss the main difficulties of database access and network security of small town's e-government system. After a case of e-government system is studied in Hengdian (a town in Zhejiang province), solutions are put forward...
Aimed at the puzzle to realize exchange and integration for heterogeneous data, this paper proposed a sort of data exchange model of heterogeneous database based on middleware unified platform. Based on the mapping of model drive, the data exchange could be realized by a concrete model. Its thought was to express XML document being a tree composed by data object, in which each element type corresponded...
The complexities of current space programs result in similar databases used across a widely distributed team. A centralized database can be an excellent way to streamline data interfaces between the distributed users. This centralization often results in confusion about the process by which data is collected and distributed, increases cost, and without proper architecture can introduce unnecessary...
Nursing-care data in this paper are Japanese texts written by nurses which consist of answers for questions about nursing-care. The nursing-care data are collected via WWW application from many hospitals in Japan. The collected data are stored into the database. The nursing-care experts evaluate the collected data to improve nursing-care quality. Currently, the collected data are evaluated by experts...
One of the most important decisions researchers face when analyzing the evolution of software systems is the choice of a proper data analysis/exchange format. Most existing formats have to be processed with special programs written specifically for that purpose and are not easily extendible. Most scientists, therefore, use their own data-base(s) requiring each of them to repeat the work of writing...
The presentation introduce the S95 standard and the implications for manufacturing database design. It covers the information exchange between the enterprise and control systems; what information, activities, resources and functions are involved and how they need to be organised and structured. The presentation concludes with the advantages of S95 including reductions in risks, errors and costs associated...
Database reengineering consists in deriving a new database from a legacy database and adapting associated software components accordingly. This migration process typically involves three main steps, namely schema conversion, data conversion and program conversion. This paper presents a wrapper-based approach to automating the program conversion step. The proposed approach combines program transformations...
