网络环境下的数据库应用及研究

Research on the Network Database and Its Application

主要针对网络的两大主流技术C/S结构与B/S结构,进行充分比较和分析,C/S结构适合于局域网及安全性要求高的系统开发模式,而B/S结构适合于安全性要求不高且成本较低的一些系统开发模式.还阐述数据库在网格上数据共享访问、最小的冗余度、数据一致性好、数据的完整性和强有力的访问控制等应用特点,及数据库访问标准ODBC与JD-BC,ODBC提供给程序员一般的访问数据库内容的简单方法,而JDBC是针对JAVA语言设计的访问数据库内容的方法及网络数据库受到的威胁问题和网络数据库安全问题的解决办法,如采取相关的措施:用户标识和鉴定、存取控制、审计、数据加密和视图等.

The paper mainly presents two mainstream technologies, B/S structure and C/S structure, and comparison and analysis between them. The structure of C/S suites for LAN and higher safeties of the system development mode, while structure of B/ S for the lower safety and lower cost system development mode. It also puts forward applied characteristics such as the shared data interview, minimum redundancy degree, the good data consistency, integrity and the powerful interview control. There is the standard accessing database ODBC which provides the simple way to programmers to access the database, and JDBC which is the simple way to JAVA to access database, The methods are offered to deal with the threat and the insecurity to the network database.
