摘要
基于数据库的web信息系统中需要与数据库有大量的信息交流,高级编程语言和数据库系统本身都在发展,它们的功能也越来越强大。信息系统的功能可以有2种途径实现:在应用程序中用高级语言编写实现;在数据库中用过程实现。原理上能在数据库中编码实现的功能在应用程序中都能实现,但他们的各种性能是不一样的。
There are many communications between database library and application in web information system based on database. With the development of advanced programming languages and database. They are becoming more and more powerful. The function of application system can be realized by two means: wrote in advanced programming languages in application; realized by procedure which included trigger, stored procedures and stored functions. In principle all the function can be realized in the application in advanced language, but there are differences in many aspects.
