Design And Implementation Of A Messaging System Of Tax E-Service Channels For Local Electronic Tax Bureau

In today's society,BigData has become ubiquitous ever,penetrated into every field of industries and business area.Our country formulate development strategy to develop smart city,smart industry.As an important part of the national tax,local tax's electronics,intelligence plays an important role for smart city development.Golden Tax Phase III as a new stage in the development of e-tax,has been launched building in the country.Based on the original tax-related information system,Golden Tax Phase III has been asked to make integrated use of the original systems,business services and data.Thus,integration legacy systems and building the basic platform become the main problem.Aiming at the need of e-tax in channels management and and channels interconnection and integration,this thesis mainly focuses on tax channels interconnection for the purpose of intelligent,and dynamic,integrated e-tax bureau and service-oriented as a design system idea.Based on depth analysis of channel management and interaction requirements,design service-oriented messaging architecture,design interactive messaging system interface and bus-based services.The main contents of the thesis include:1.Detailed analysis and modeling of requirements functions and interactive data of channel management and messaging system is made.It inludes modeling functional requirements with UML use case model,modeling the system data with ER logical diagram and interface requirements analysis and system performance requirements.2.On the basis of systems analysis,the overall architecture of channel management and technology architecture of messaging system are designed.The system uses the integration of ActiveMQ and Apache Tuscany SCA Java with Java EE,to build an ESB platform as the underlying messaging system platform.From a logical point of view,system functionality is divided into two modules,channel management and message management.From a technical point of view,using of hierarchical design,the technical architecture of the system is divided into the presentation layer,application service layer and data layer three.Physical model of the database is designed.3.The detailed design of the functions of channel management and messaging system is conducted,using UML sequence diagram or a flow chart describing the interaction flow between objects.The functions include channel configuration and start and stop,the message configuration,message sending,message feedback/response,monitoring and management,and query statistics.The message packets of the messaging system are designed to interact across channels,using XML message,including return codes,the caller Web service and requests and other service requests.The design of the interface system provided externally is detailed,including channel access interface,start-stop channel query interface,the application system to send text messages via mobile phone number directly from the interface and applications via mobile phone number to send direct mail interfaces,application messaging system interface.4.Integrated development environment,Eclipse,Java language and Web front end technology are used to implement the system.Hardware and software operating environment are configured,and as a foundation to carry out functional and performance testing.Functional test include message including group maintenance,subscription messages,sending messages,and other related query modules.System performance testing include the system pressure and performance using professional testing software with large amounts of data and large number of multi-channel users.Test results show that the realization of channel management message system meets the design requirements,provides for the entire e-tax messaging guarantee to achieve the integration of electronic channels with good stability and practicality.It's already seen the promotion of higher value.
