Design And Implementation Of Secondhand Market Subsystem For Micro-blog Based On Google Map

With the rapid development of internet technology and satellite remote sensing technology, the distance between people is slowly declining. With the interest in geographic information rapidly increasing, Google Map has also emerged. Google Map provides users with comprehensive geographic information positioning function and a strong visual impact and bringes limitless market potential. So we combined micro-blog with Google Map and have successfully built a micro-blog called “weisibo” which is the first micro-blog in China with which messages can be sent to the map. Then many other micro-blog websites in China gradually built similar function, but "weisibo" has provided a platform for users to communicate with the map, allowing users to locate any place to send a message which increases the users’ experience and flexibility when sending a message, which can not be matched with micro-blog sites. With the experience of the micro-blog on map, we built a secondary market based on Google Map platform, I believe that we wil success again.This thesis firstly analyzes the development of domestic micro-blog and the disadvantage of domestic secondhand market, introduces a number of technical difficulties encountered, including how to develop the MVC framework based on PHP, how to develop REST API, how to use the Google Map API, demonstrates technical feasibility. Then, combining micro-blog and secondary market demand, builds a system architecture that combines the MVC framework and REST thinking, which can reduce coupling, increase reusability and applicability and provide favorable to the third-party access to web resources API. Then, for the system design, implementation, I finished the secondary market module function: release and management of second-hand merchandise, and display on the map, and complete set of REST API. Finally, I created a separate desktop to test the API’s usability by Flex.This paper is mainly divided into five parts to introduce the content of the thesis, the first part is introduction,this part introduces the research background and significance, the present situation of the domestic development in this research area, and then introduces the demand of the system, including demand analysis, functionalstructure analysis,functional module analysis, structure analysis and feasibility analysis and development environment. Then the paper introduces the system design, introduced the system design ideas and principles, architecture design, database design,interface design and module design. Then it introduces the system implementation,the main function are introduced in this part, finally is the system testing and the conclusion.Final conclusion: the combination of secondhand market and Google Map has practical significance and feasibility.
