1 Introduction

With rapid development of the Internet，e-commerce platforms are widely applied in various fields.Compared with traditional shopping ways，e-commerce is convenient and swift.We can select and buy desired products with outgoing outside.Besides，the price is of real benefit.However，e-marketing is relatively few in agricultural products and e-marketing of agricultural products is relatively backward.Two fundamental factors lead to this problem.Firstly，producer end and customer end of e-commerce of agricultural products have numerous separate producers and consumers.How to connect them through an effective e-commerce platform and logistic system and realize rapid circulation of agricultural products between them is a complex problem.Secondly，agricultural products have short shelf life and are perishable，so the e-marketing cost of agricultural products is higher，but the low added value of ordinary agricultural products fails to support operating cost of e-commerce enterprises and logistic distribution［1-4］.This system selected＂three brands and one identification＂（green，organic and nu is anceless and geographic identification）agricultural products of specialized farmers'cooperatives in Shanghai.Such products have higher commercial value.With improvement of people's living standards，people care more and more about health and become urgently to eat fresh agricultural products.In view of this situation，we designed and expected to realize the e-marketing system for fresh agricultural products with the reference to e-marketing operation experience of mature e-commerce platforms on the basis of e-marketing of fresh agricultural products in Shanghai.E-marketing of fresh agricultural products can expand marketing channels for specialized farmers'cooperatives，increase farmers'income，expand businesses of e-commerce enterprises and increase their profit for e-commerce enterprises.For consumers，they can buy fresh agricultural products，which are favorable for their health.Thus，e-marketing of fresh agricultural products is of great realistic significance.

2 Analysis of system demand

From the production to consumption of fresh agricultural products，it mainly include following links［5］.（i）Farmers produce agricultural products，while specialized farmers'cooperatives are mainly responsible for centralized collection of fresh agricultural products and supplying to e-commerce enterprises.（ii）E-commerce enterprises are responsible for quality inspection，classified packaging，storage and sales management of products.In other words，cooperatives supply products for e-commerce enterprises，and e-commerce enterprises package agricultural products according to content of purchase orders，and then make real-time delivery.In this process，e-commerce enterprises should have certain fresh product stock condition.（iii）Consumers can browse，search，order and make payment for products.According to actual application demands，we can divide system users into 3 types：（i）specialized farmers'cooperatives；（ii）e-commerce enterprises；（iii）consumer members.If logistics and delivery are not self-operated by e-commerce enterprises，it can add third-party logistic susers.The system is provided with interface for third-party logistics.

E-commerce has different business modes.According to the above analysis，this e-marketing system is designed to be B2B2C（Business-to-Business-to-consumer）mode.

4 System realization technologies

4.1 System development technologiesThe system developmentadopts PHP（hypertext preprocessor）.PHP isan HTML-embedded scripting language.Much of its syntax is borrowed from C，Java and Perlwith a couple of unique PHP-specific features thrown in.The PHP is easy to learn and has become one of the largest mainstream development technologies for website development and construction［6-7］.

The back-end database adopts Oracle database.The Oracle database is a relational database management system（RDBMS）from the Oracle Corporation.Oracle database is one of the most trusted and widely-used relational database engines.The system is built around a relational database framework in which data objects may be directly accessed by users（or an application front end）through structured query language（SQL）.It is a fully scalable relational database architecture.It is often used by global enterprises，which manage and process data across wide and local area networks.

Oracle database has following features［8-9］：（i）complete data management function：numerous，long storage long，data sharing，and reliability；（ii）distributed processing function；（iii）performance：high usability，high extensibility，high data security，and high stability.Oracle database is one of the first choices of large websites and e-commerce platforms.The system development and operation are realized in Linux operating system.

4.2 Ajax technologyThe core of Ajax is JavaScript XmlHttpRequest.This object is firstly introduced in Internet Explorer 5.It is a group of interrelated Web development techniques used on the client-side to create asynchronous Web applications.Ajax is not a single technology，but a group of technologies.With Xml Http Request，you can make request to the server and process responses.It does not block users.It can make update of the website without loading the entire web page.Now，Ajax has been widely applied in website.In this system，we mainly adopt this technology in the marketing module.After the member logs in，it can ensure browse of products page by page，making comment of browse，and making comment after purchase.It can realize asynchronous data loading and display of web page content.This not only ensures smooth browse of members in the process of shopping，realize excellent shopping experience，and greatly reduce website traffic of e-commerce enterprises and server burden.

4.3 Payment realization technologyThis e-marketing platform adopts flexible and convenient payment methods：cash on delivery，credit card on delivery，score payment（online recharge），and third-party payment platform（such as Union Pay，Ali pay，and 99Bill）.

4.4 MVC framework develop ment This e-marketing system adopts MVC（Model View Controller）architectural pattern.MVC a software architectural pattern for implementing user interfaces.It divides a given software application into three interconnected parts，so as to separate internal representations of information from the ways that information is presented to or accepted from the user.The model directly manages the data，logic and rules of the application.A view can be any output representation of information，such as a chart or a diagram；multiple views of the same information are possible，such as a bar chart for management and a tabular view for accountants.The third part，the controller，accepts input and converts it to commands for the model or view.MVC makes model classes reusable without modification and also makes the view reusable without modification.This development mode is favorable for labor division and cooperative development，increasing development efficiency，favorable for update of website layout without modification of business logic，and also favorable for operation and maintenance of the system.

5 Conclusions

In this study，we introduced the e-marketing system for fresh agricultural products.This system adopts PHPbased MVC framework technology and the database adopts Oracle database.This system has already started providing platform construction and operation and maintenance services for many agricultural product e-commerce enterprises，such as Shanghai Agriculture Information Co.，Ltd and Jinhuize Agricultural Product Marketing Cooperative.Since its operation，this system has realized the objective of winwin of three parties：（i）specialized far mers'cooperativesexp anded their marketing channels，increased far mers'income，and enhanced farmers'enthusiasm for planting agricultural products；（ii）e-commerce enterprises got familiar with operation mode of fresh agricultural product marketing，expanded their business scope，and increased their profit；（iii）consumers can purchase desired fresh agricultural products through this platform.Thus，construction and operation of this e-marketing system for fresh agricultural products greatly promote rural informationization of Shanghai and also play a model and leading role in construction and application of fresh agricultural product e-marketing system in other domestic regions.
