文档介绍：基于J2EE招标信息管理系统的分析与设计
摘要
J2EE是一种利用Java 2平台来简化企业解决方案的开发、部署和管理相关的体系结构。当今许多企业都需要扩展业务范围,降低经营成本,缩短和客户之间的响应时间,这就需要存在一种简捷快速的服务在企业,合作伙伴和雇员之间。提供这些服务的应用软件必须同企业信息系统(EIS)相结合,并提供新的能向更为广阔的用户提供的服务。本设计用JSP+JavaBean来实现招标信息管理系统,结构上采用管理端与客户端分离的方法来实现,思想上采用面向对象机制,将项目、产品、厂商等封装成数据类,并且每个类都有对应的操作类;结构上采用界面、业务逻辑和数据分离的三层结果设计;数据库连接上采用了连接池,以此来提高数据库效率。

J2EE tender information management system analysis and design
ABSTRACT
J2EE is a kind of system framework which using the Java 2 platforms to simplify the enterprise solution of the development, the deployment and the management。At present, there are many enterprises all need to expand the business scope, to reduce the cost of operation and the response time with the customer, this needs to exist one kind of simple and fast service in the enterprise, partner and employee. software which can provide those service bine to the enterprise information system (EIS), and provides new capability which can expand the user. This design implement the tender information management system with JSP+JavaBean, in the structure ,which uses the method to separate management end and client side; in the thought, which uses the object-oriented mechanism, of which classify the project,the product, merchant to data, each kind all has corresponding operation class;in the structure, which uses the interface, business logic and the data separation three layer design; the database–connecting use the connection pond to enhance the the database efficiency.
