Realization Of Web Database And Security Precaution

With extension of network and maturity of database technology, the complement of the Web and the database thchnologies decides that their merge is a ubdoubtedly trend . The henteractivity of web with database is the path to realize information service,it has important applicatin worm. For this,the article will make discussion web databasec technology from five aspects: Web database structure, web database perfection, web database access method, and Web database security.In each chapter the article tells advanced theory and technology in concerned field and gives full solution method.Now, technology of web database is comparatively mature,web database system is constructed on C/S or B/S model ordinally.Chapter 2 tells C/S or B/S scheme, how to select structure, puts forword C/S or B/S model, middleware.No matter what to design web database structure,data alternation among computers is frequent, each computer confronts speed problem of data access, data fefresh, data alternation. So the design and perfection of web database system is important. Chapter 3 discusses web database perfection:MIDAS technology, XML structure, code thchnology of improving data access speed.Chapter 4 summerizes database access method, gives advantages and disandvantages, intent warning of data access.Chapter 5 discusses web database security from Three aspects:user, web server, database, at the same time we give a factual solution method on basis of theory.Chapter 6 adopts the study method of theory study and school network experiment plat. On basis of theory this article put forward database system solution method, security method. In practice construct web database system on C/S model, SQL Server2000 system and Winnt2000 Server to develop work of security protection, database perfection.
