The Enterprise Mail System

The economy develop very quickly,but the schools in the west has no a computer,it is worthwhile pleasing that a lot of people with warm heart and charities have donte many computers to these schools.Although improve learning standard ,they are not be able to connect Internet.We develop the program for they are capable of communicate each other on the inner network..The mail system adopt as an interface as one on the inerenet,which is convenient and efficient.The operation modules comprise of the administor and subscribers modules. The administor modules consists of logon subscribers administration system setting .And the subscribers modules consists of registration logon modul,mail sended and received moudul,inbox administrated moudul and correspondence book modul .The managing person registers a mold piece: The managing person wants to carry on the system management, will own an own logging entrance, this is the demand of the whichever system management function confidentiality.Know according to the design of the database part, the managing person's customer deposits in the data form myuserr in, the beginning started to turn to stuff with a managing person's customer a record, the customer was an admin, password is test.Managing person the customer management mold piece:The managing person is the mail system management after register, the initial function is the management to the system customer and the system parameter.The managing person's management the main page has an entrance of enter the customer management and the system parameter constitution management up.When the managing person carries on managing an operation after, withdraw management interface, then want to withdraw the exit of[with] management.Managing person the system constitution mold piece:The system constitution management and the backstage system allocation table to should, mainly include the URL,main page name,main page URL,system managing person E-mail etc. of the system name,system.The customer registers a mold piece:The mail system conduct and actions a kind of information exchanges outlet and tool, in the system in addition to system the managing person is all general customers outside all system customers.Can know according to the anterior need and the design, pass the network usage mail system to then need registration in advanced line, record personal information and the registration information of the customer to get to system in, for the purpose of usage the management work of the system and system managing person.The customer registers a mold piece:The customer register hereafter, can use the function of this system.So, the logging is an usage the entrance of these functions, record an own information because of the different customer demand, need system to distinguish analyse each logging customer and then can make according to the user's name the system circulate normally.The customer composes to send out a mail mold piece:After customer register, the main work is the management to the mail, after all this is a mail system, so the system tacit approval enter to the interface of[with] the mail management.But the mail management is divided in to accept a box,preliminary draft box,deliver a piece of garbage-box,correspond by letter a book and send out mail again etc. function, so want to all design a button for them, the single shot each button, then enter each from of function interface. The customer accepts a box management mold piece:The customer send out after mail go out, the consignee can immediately see receive in accept a box of all mails.Peaceful mailbox that the hour use accepts a box similar, this interface is the contentses such as the row form information, concrete manifestation addresser,topic(the headline of the mail),date and size etc.s of all mails.The customer correspondence book management mold piece:While use the mail system, the customer in the system generally all is up thousand,around ten thousand, impossibly intentional of to all remember an user's names of, that is also not realistic, so can increase the customer that usually needs to contact to the correspondence book, be to want to send out personal information that the mail looks into some customer perhaps to the some customer, as long as go to correspondence to check to seek in the book.On part of frame ,we adopt standard MVC of three layers(JSP-JavaBean-Servelet) developing model.Through such design model we come out application logic,operation process,display logic by sepatate modules. The modules are so interactive and reusing that we improve development efficiently very much.On part of design the system adopt oop software engineering ideas .According to demand ayalysis system analysis system design object design object realization the system finish analysis and design .Oop programs designing exceed structure programs in follows:The first is that it has effectively solved two main problems about soft engineering---the control of software programs complexity and improvement of software productivity. The second is that it accords with human's thinking and present realism .UML is a modeling language which is easily expressible,has a powerful function . Using of UML range from computer science area to business area .
