The Backstage Management System Of Online Booking Website Based On Four-tier Architecture

With the rapid development of Internet,Constantly bring convenience to people at work or in life,Including the transportation industry,a variety of traditional industries are also changing with the development of computer information technology.Compromise the Internet information technology,not limited to the traditional station ticket or telephone booking mode,more and more passenger-transport enterprise has demand on the expansion of new ticketing channels.Passengers buy tickets at home,the company updated passenger transport dynamics immediately,information-based management on daily things,The establishment of online ticketing platform become the solutions to meet these needs,so that enterprises can adapt the new situation of development.On the other hand,In the context of the fifth Plenary Session of the 18 th CPC Central Committee,Ministry of Transport issued the "traffic information“thirteen five”development plan" document is to specify the transformation of the traditional transport industry should choose "Internet +" direction.Therefore,it is of practical significance and application value to develop a set of background management system which is suitable for the passenger transportation enterprise networking ticketing website.In this paper,according to the actual development of transportation enterprises and the requirements,combined with the current situation of the development of the Internet,Using the popular B/S structure model in development,Microsoft.NET as the development platform,Integraten ExtJS,Spring.NET,Nhibernate technical framework,to develop a background management system for passenger transport enterprise networking ticketing website that stable,easy to use,easy to expand,easy maintenance.The main work of this paper: Starting from the design of system architecture,analyzes the shortcomings of the typical three-tier architecture,introduces the IBLL service interface layer and the IDAL data interface layer,combined with the design pattern of MVC,propose the four-tier architecture model.In addition,on the basis of this architecture model,the design of presentation layer uses ExtJS framework that based on JavaScript,through object / relational database mapping tool Nhibernate to complete the persistence of the object,use the Spring.NET framework as a container to define application objects,assemble its dependency class,the scattered components are combined into a complete application.Then,combined with the analysis of demands,develop and realize a backstage management system of the passenger transportation enterprise networking ticketing website.The system can achieve the management of the ticketing website,such as enterprise related information dynamic and management of ticket order information.Currently,It has been come into use in several passenger transport enterprises in Guangdong Province,shows that the development of this system not only meets the demand of the passenger transport enterprises mentioned,and laid a good foundationfor the future expansion of functional requirements.In addition,the successful application of the system verified the feasibility of the four-tier architecture model,not only provide value for others to learn,but also pave the way for the development of Web.
