The Application of Database Technology in Information Society and its Existing Problems

With the development of computer technology and network communication technology and multimedia technology,database technology has become an important technical means and software technology for organizing and managinglarge amount of data in information society. It is the foundation of network information management system. Itnot only has a complete theoretical basis, and with the rapid development of hardware technology and softwaretechnology, its application is more and more widely. However, the rapid development of information technology isthat people face such a situation: CAD / CAM, CIMS, CASE, GIS and other applications require the managementof increasingly complex information, such as multimedia data, such as multimedia data, spatial data, scientifi c data,Data and other data types, these data compared with the traditional type, not only the type of complex, diverse forms,and storage, transmission, operation and retrieval methods also have many new features, new requirements, on theone hand, the need for database technology and database systems To manage these complex data in order to obtainthe database system has many of the data management functions, such as query, retrieval, recovery, concurrencycontrol, integrity, storage management. On the other hand, due to the vigorous development of network technology,information processing has long been from a single user environment to the development of the network environment,this environment for resources, information sharing provides a great convenience, and because of multi-machine worktogether to greatly improve the work , The combination of the two requires that the database management system beable to manage complex data objects in a networked environment or heterogeneous environment. Traditional DBMSscannot eff ectively handle complex multimedia data, thus requiring the use of new multimedia indexing and retrievaltechniques. Multimedia database technology is an important part of computer technology, it can simultaneously acquire,process, edit, store and display text, sound, video, graphics and other diff erent media, while it has diversity, integrationand interactivity and so on. Only to solve the key technical issues of multimedia, can be widely used to promote itsfaster development.

Application of Database Technology in the Software of Seismic Data Acquisition

A software of seismic data collection was developed based on building a surface data base. The software represents a better way to manage seismic exploration data. The Browser/server (B/S) and the Client/server (C/S) are used to realize integrating the function of processing/interpreting and querying together. This study improves the methods of processing the surface seismi c data on spot outdoor nowadays and accords wit h the demanding of digital construction of the oil field. It is very convenient to operate with this software, either on spot outdoor inputting data or querying and later processing/interpreting indoor.

The Application of Database Technology in Network Management System

Web-based network management revolving about database puts forward a feasible mode for network information processing and has the characteristics of wide distribution, full interactivity, real-time dynamic and so on in the application; and is beneficial to timely adjustment for network performance and rapid recovery for fault. Combining the technologies of JSP, JavaBean, JDBC, Socket, JavaApplet, Ajax, JavaScript and so on, database-centric network management mode ensures the reliable, efficient and stable operation of configuration, performance, fault, security and accounting management in the development of business network management system, such as TD-SCDMA network, PON network, TMPLS network, IPTV network, power network and so on. In practice, it is worth mentioning that it improves the dynamical and real-time release performance of accounting management, realizes web-based management for rate and bill. Customers could receive bills real-timely in internet and deals with them conveniently. This is propitious to the management of network vendors as well.

Application of Database Technology in Fault Extract for Shipboard Power System

The shipboard power system network dispatch automation was a recently developed technology which can effectively enhance supply and distribution electrical power system safe operation ability and reliability. With science and technology development, the shipboard power system is getting more and more complex, it is very important to extract the fault accurately and quickly. Based on the characteristics of the shipboard power system, the database technology was used to solve the fault extraction for the shipboard power system network. Simulation results showed it can satisfy real time request and process multi-fault situation appeared in the system and show all the fault branches information.

Research on Applied-Information Technology with Application of Data Mining in Analysis of Consumer Behavior

With the development of computer technology, especially the rapid development and extensive application of database technology and computer network technology, the data quantity increases sharply, the accumulation of a large number of data in various fields, and rising fast. Enterprise database or data warehouse has stored a large number of customer data, these data include many aspects of the information of customers, but also contains the advantages and disadvantages of the enterprise operation. If we can use these data quickly, efficiently in-depth analysis and research, to find the rules and modes, to obtain the necessary knowledge from it, will help enterprises to better decision making. The system can successfully excavate students and staff of the tendency of consumption and consumption habits, analyze their satisfaction with each restaurant. The results of system analysis to a certain role for school students and teachers to understand and analyze the condition of daily consumption, so the establishment of this system has great practical value.

Data management to enhance long‐term watershed research capacity: context and STEWARDS case study

AbstractWater resources are under pressure globally due to growing population, human migration into arid regions, and diverse competing needs. In recent decades, progress in the study of information (informatics) and its manipulation via computer‐based tools has stimulated development of data systems in many natural resources disciplines. Such informatics systems provide data storage, access, visualization, perhaps with analysis/modelling tools, and download capacity. Application of database technology can overcome problems of fragmentation, inadequate documentation, and cumbersome manipulation of complex data. Data management was a critical requirement for USDA's Conservation Effects Assessment Project (CEAP) which was established to quantify environmental effects of agricultural conservation practices. Although USDA and the Agricultural Research Service (ARS) have conducted watershed research since early 20th century, the data have been managed and disseminated independently from each research location, reducing accessibility and utility of these data for policy‐relevant, multi‐site analyses. To address these concerns, STEWARDS (Sustaining the Earth's Watersheds—Agricultural Research Data System) was developed to compile, document, and provide access to data from loosely coupled research watersheds. The STEWARDS case study is used to illustrate the role of data management in enhancing ecohydrological research and evolving information technologies available to improve data management from complex ecohydrologic studies.

APPLYING DATABASE TECHNOLOGY TO CLINICAL AND BASIC RESEARCH BIOINFORMATICS PROJECTS

This paper describes the application of database technology to medical information with the goal of providing medical and clinical researchers with the tools necessary to plan bioinformatics projects. Commercial database management systems were utilized, standard database design practices were applied, a user interface was created, data entered, and the development of analysis tools, including data mining technologies is underway. Databases were constructed based on animal and cell culture models of diabetes and clinical data. Bioinformatics is a useful tool in both basic research and clinical settings. The advantages of relational databases and an approach to managing bioinformatics projects are discussed.
