| With the rapid development of network database and the wide application of cloud technology,China’s digital library has made great progress.But,at present there are still quite a number of library management system is still in the relatively independent stage of information island,implement multiple branch or resources sharing between university library and community library has become the development trend of the library management system.Because of the real-time data management requirements and cyber attacks,security problem of library management system is the necessary condition of the development of digital library,and become one of research focuses in the current library management system.The main problems in digital library in China are low security,low access efficiency and poor compatibility.Data security is a major obstacle to the construction and application of school resource platform.On the basis of the existing library management system,this paper USES hash function to encrypt the distributed network database to store data,can solve the problems in the library management system security is low,academic resources and protect the security and privacy of user information.In addition,this paper focuses on its network security research while studying the application of network database in library management system.Focuses on the security requirements of network database,presents a suitable for the system security policy structure of the library in colleges and universities,with a firewall,intrusion detection,authentication,access control,data encryption security technology such as construction of network security defense system,and the data backup strategy has carried on the detailed description.After the demand analysis of the development of library management system,a suitable database construction method was designed according to the requirements.In this article is mainly to SQL Server as the database platform,because of its low price,function,friendly user interface,as well as the characteristics of the Windows system comprehensive integration and widely used in all walks of life,in a distributed Web applications play an important role.Its data store can contain all the data types,including user application preferences,confidential personnel records and medical records,and readers borrow archives,audit log and security log,and even users access to the application when the credentials required.Obviously,you need to ensure their security when storing such data and performing read/write operations to ensure that only users with corresponding authorization privileges can access them.Finally,in order to guarantee the development of the system,and puts forward the security measures of library management system,database configuration and security environment,put forward the requests of the development environment,has carried on the system architecture design.At the same time,on the basis of the comprehensive analysis of the establishment and security of the database,the practice of database security problem setting and design has been done.This paper discusses the security problem of network database in library management system,puts forward a set of reasonable solution,and carries out the security configuration and implementation of the database.It provides a safe reference for the application of network database in library management system. |
