The Design And Implementation Of Network Trading Platform System Based On XML

Since the adventure of XML technology,XML has been widely used for data representation and data exchange on Web.In recent years,with the extensive application of XML technology,web has the emergence of the large number of XML data.How to more effectively manage these massive XML data has gradually become a research hotspot.In recent years,people in the XML document compression and storage,queries,etc.do extensive research.But as the XML data is increasing,people for the storage and query of XML data proposed higher requirements.Therefore,in the thesis,the XML data compression storage and data compression of the direct query has been explored.First of all,the thesis has made the deep research working on the existing coding schemes based on interval coding and prefix coding,and introduces the typical coding schemes in detail.The compression coding scheme has based on interval coding is proposed,and the storage structure and coding algorithm used in this paper are introduced in detail.The coding scheme can't only save storage space,realize the compression of XML data,but also can quickly determine the location of nodes,and improve the efficiency of query processing.In the thesis,the design of the network trading system is based on XML technology development and design,its main characteristic is can effectively deal with the customer's request and has more simple.More convenient database access method,it is easy to maintain and update and use MySQL database functions,to facilitate the management and statistics of the buyers,merchants,the commodity basic information.The electronic commerce transaction platform in the thesis is composed of three main subsystems,which are the information service subsystem,the commodity issue subsystem and the backstage management subsystem.User login website is the first to do is to register,get a registered account,and the user's registration to detect,to ensure that the user is legitimate.When after the successful registration,the user can ask the store according to their needs,or free to purchase goods.Decided not to buy goods can be put into the favorites.Successful shopping users can assess the quality of the goods and services after the receipt of goods.In order to ensure a better shopping experience,when the user to buy goods,you can also choose two kinds of classification and fuzzy query.After selected commodities,they can get in touch with the stores by mail,offline transaction.And the system administrator can to all the registered owner and member customer management,including add,delete,auditing,and management of commodity information has been released.
