文档介绍：摘要
可维护的数据库浏览器,采用基于Web的多层应用模型。程序上采用MVC结构,可以将数据存取逻辑与数据表现逻辑分开,组合JSP Servlet和JavaBean来建造灵活与可维护的应用程序的设计模式。
。接着,应用程序会允许用户浏览数据库中定义的所有表,并且可以选择任何一个表对其数据进行处理。同样,用户还可以输入SQL查询语句并查看这些查询操作产生的列表数据。在用户使用会话的任何时间内,必须确保用户可以很容易地断开数据库,并连接到另一个数据库上。
关键字:MVC、设计模式、多层结构。
Abstract
The data base browser that can be maintained, adopts the multilevel application model based on Web, Procedure adopt MVC structure, can deposit and withdraw data logic separate from that the data display logic, Come to build flexibly with the design mode of the application program that can be maintained.
Web request of interface to allow user content to have a look around relevant data base. Interface this make user can connect through appointed one JDBC driver or URL with a data base. Then, the application program will allow users to have a look around all forms defined in the data base , And can choose any form to deal with its datum . Equally, user can also input SQL inquire the sentence and look over that these are inquired about and operate the tabular data produced . Until what user use conversation any time, must guarantee user can disconnection data base very easily, And connect to another data base .
Keyword: MVC Design the mode Multilevel structure.
