摘    要:介绍了如何设计和实现一个基于模式的J2EE快速查询生成系统。系统主要有两种角色的使用人员,设计人员与用户。系统让设计人员定义面向用户的数据库信息,包括表、表的字段及其显示风格;系统允许用户从已设计好的界面模式中选择自己喜欢的界面风格,在用户定制完自己的查询内容后,系统采用广度优先搜索来判断查询的合理性,并用最短路径算法优化查询。系统极大地简化了基于Web的查询系统的开发和维护。

关 键 词:设计模式  J2EE  用例图  序列图  深度优先搜索  广度优先搜索  无向图

Abstract:How to design and implement a rapid building system for query is introduced based on design pattern using J2EE technology. The system contains two operating roles that are designer and user. The designer will define the tables, fields in table and their styles that are visible to user. The user can select user interface patterns that are implemented by the system. After the user selects all his or her fields for query, the system will validate the query based on broad-first search. The system also optimizes the query execution using shortest-path algorithm. The system make it easy for developing and maintaining query system based on web.
Keywords:design pattern  J2EE  user case diagram  sequence diagram  depth-first search  broad-first search  undirected graph
