Design And Implementation Of 139mail Delivery Platform

With the development of market economy, the demand of various bills is growing rapidly. Now the email bill business has been involved in the financial, livelihood, government and other industries, it has been widely accepted and recognized by the community.In this research topic, 139 mail delivery management platform(referred to as "delivery platform") project, use 139 email system as a carrier of various bills, set up specifically for China Mobile user’s mail delivery management platform, realize the company of business delivery, statistical analysis, system monitoring and other’s demand.In this system,I designed a data validation component, based on JSON format’s regular expressions configuration,it has web and server dual data validation mechanism;I designed a access control component with business and functions dual authority mechanism,it strictly control the user’s business operation, functions Authorization let the pages divided into free login, login authentication and authorization to the three categories, it strictly control the user’s functions operation;I designed a page cache component,it using the local session cache, without asynchronous request the server, can record the user quickly return to the last page, including the HTML element and the final historical status, the history asynchronous data, and the user history input;I designed a single sign service component, unified user authentication mechanism for the interaction between the system, establish the key check, business authentication, IP authentication of the white list;According to the module design and content delivery user management, templete management, mail data management, work order management, business management.This paper adopts multi-layer architecture pattern, design of system overall structure.Through the UML model class diagram, collaboration diagram, flow diagram and other tools to business scenarios and functional requirements analysis, design and implement.In the Windows development environment, using C# language,.NET framework technology to program develop, and with the use of memcached caching system, My SQL database, build a common set of platform system.This system is fully tested by the test case, to meet the construction requirements,it has been used in the enterprise to achieve the normal online, easy to use, fast, efficient delivery of mail goal.
