The Design And Implementation Of Integrated Payment System

With the rapid development of computer network technology，the network services basedon WEB has increasingly gained the majority of e-commerce businesses favor. Modern enter-prise in many ways follows the pace of IT development, at the same time, make full use of allkinds of electronic commerce system which provides a good platform to complete theefficient commercial operation. According to this idea, the system uses the object-orientedJava language, based on SSH architecture, developed a comprehensive order paymentsystem.In the implementation, integration of Ajax technology and a powerful clientframework are used to integrate into the full-featured report module. Using the order as themain line, the customer(login again) as the main body, realize the rapid trading between theenterprise and the customer and the information interaction.Aims to promote the productsand services of the Internet companies, through the application of the system so thatcustomers know the products of companies and enterprises, the online services and orderprocessing features.First, the paper analyzes the subject background, the development of meaning andpurposes described in detail. Introduce the development environment and tools in systemdesign and analysis section of the system’s functional requirements, performancerequirements, reliability and availability requirements, error handling needs, interfacerequirements, constraints, reverse demand in the future may be requested. Integrated ordermanagement system requirements for agents and suppliers to achieve an online tradingplatform, providing online order management, inventory management, campaign management,message notification, online payment and other functions. Divided based on function modules,integrated order management system is mainly divided into two parts: agent subsystem andsuppliers subsystem. Agent subsystem, including setting the Message Center (view message),contact a vendor, order, order processing, receiving, order tracking, and statistical reports.In order to standardize the naming of the database design, field type, length and otherfactors, in order to strengthen the management of the table name, easy to understand anddevelop the system, and developed a table name naming rules. Table birthright level by theletters of the alphabet between the composition, level with "_" to connect, basically consistentwith the product.Regulate the design, options dictionary database only option dictionary for possible expansion options, the option can not be expanded without the use of options such asBoolean or the other, the dictionary, can be cured in the program. If the documents do Logowithout using the option dictionary, but the underlying data may have more than one state,use the option dictionary. Do not provide any means to the user to expand the option ofsystem-level implementation or developers can add options through special means, and acorresponding increase or modify the program to deal with new options. User-level option,the setup tool by the user to add, delete, change..For user level options provided by the user,the setting tool, add, delete, change.The option is generally constitute identification number toa numeric type of option content.If the identification number1normal,0representative voidedetc.The system has the option of a choice, in order to reduce the number of tables, the optionto design a system dictionary table, unified dictionary library to save only one option. Design,data tables complete the table structure design.Data import and export XML-based file system does not support JSON formatted data filespassed between heterogeneous systems. Although this format is to save resources, but not asgood as the XML specification is not conducive to a flexible definition of the data containedin various types of property.Finally the paper describes the detailed design of the system. Public module login screen,the registration interface; agents query the agent function modules, agents order, agents orderconfirmation, payment, and agent confirmation of receipt of the design. Business strategy tomaintain the basic information of the supplier of the functional modules release described indetail.The system uses advanced J2EE technology platform effectively to ensure system stabilityand efficient operation; database system uses the the Oracle10g above version, to protectsystem data reliability and security, while improving the efficiency of the system data access.The system mainly consists of two parts of the establishment and maintenance of theforeground application development back-end database. Former requirement to establish dataconsistency and integrity, security platform, while the latter requires the application functioncomplete, easy to operate and easy to use.
