The Design Of Purchase Information System Based On Android

Group buying is a win-win market behavior, not only to meet the demand of enterprise sales and meet the common demands of market society. For consumers, through deals with less investment to buy more desirable service or commodity, and for the enterprise or the ordinary businesses, the group purchase activities to bring the demand of commodities or services on a larger scale in a short period of time, this form of service can greatly reduce the enterprise cost, accelerate the circulation of funds of enterprises. Market there are various group buys a website, the website has brought the massive information, one can classify collect all buy information website will be in a great extent reduce the cost of the user’s search, and save consumers get the information time.In this paper, we study the system of group buying information integrated system. First of all, the characteristics of several operating systems are analyzed. According to the current situation of intelligent mobile phone to become the mainstream of access network, the Android operating system is selected as the development platform of the group buying information playing system. Secondly, the paper introduces the template based web crawler technology of web page information extraction process, reference to a page of a site analysis, the introduction of the concept and usage of regular expression, summed up the corresponding web page template. Again, in view of the different sites and sites in different channels, the group buys a website content increasing and continuously updated web content characteristics, the development of data capture technology based on template, design a set of unique crawler system architecture based on the template, the crawler system at runtime by characteristics of some custom search in the template set, by automatically matching the most appropriate template to ensure the running efficiency and accuracy, then simplify the system programming and user operation. Finally, combined with massive data provided by the crawler system, carried on the test to the buy information system. The results show that the system real-time server stability, client interface is simple and efficient, the system has good usability, robustness and interactivity.
