Base On The Design Of The J2EE Newspaper Issue Management System

Newspaper is one of the most important carrier of the propagandize method for the society and nation;it has great connection with the multitude.Handcraft is the method for tradition newspaper issue,but it has some abuse,e.g.:great workload and fussy affairs,etc.Even though we adopted information system,it often chooses the C/S system structure,in this structure,the client side contains many logic of data processing, it can induce the system hard to install and maintenance.The paper based on the analyze of the J2EE multilayer frame technology,and combine the Liaoning province Liao Newspaper Group's underling the BanDao Morning Edition's prophase invention example,expatiated the general design method and exploitation flow of the construct the J2EE multilayer frame enterprise information system.Firstly,the background and application situation of the task are introduced in this paper,it indicates that the C/S system structure can not accommodate with the rapid development of the enterprise application system.In succession,the paper briefly introduce the popular program system structure,it also under the Windows platform, NET system structure and J2EE/EJB system structure,the last one can fit many kinds of platform.Enter on the newspaper issue management operation model,combined information management system with the UML and Rational Rose to analyze,design and coding the system.In the middle of the paper,it analyzes the system,in the design it adopt MVC design mode realize the J2EE application can divide up the system into eight functional modules and a nonfunctional module,these modules are independence one another,it is propitious to team side-by-side develop.The second half of the paper investigates how to design and actualize the newspaper issue management system.The mostly content contains:the technology truss of newspaper issue management system;the design scheme of newspaper issue management system;the design of information release;the design of DAO module; carry through the system design from the three parts of system optimize design;the exploitation circumstance and facility introduction of the system.
