The Design And Implementation Of Data Dissemination Process System Based On Data Of Traffic

With the continuous development of Internet information technology,people entered the era of big data and artificial intelligence.The information construction of NanJing is underway.Nanjing Information Center in Jiangsu province established the The Intelligence NanJing project which uses networking and cloud computing for storage and analysis of traffic data.Nanjing Information Center cooperates with SAP NIC whose full name is SAP Nanjing innovation center in the field of traffic.SAP NIC use SAP HANA memory database for storing large data.But there are many problems.For example,data access interfaces of cooperative enterprise are not uniform and high concurrency leads to high pressure of the database.Because HANA only provides storage process interface for data analysis so it can not perform complex calculations very well.Because the actions of read and write can not be separated so the burden of database is very heavy.Therefore,the purpose of this paper is to make a study of a data distribution system based on traffic data flow.The system uses the standard application software design architecture.It uses the design of distributed system software and combines Spring,RocksDB,Zeromq and ZooKeeper with other advanced technical frameworks.This paper focuses on this system.It puts forward the overall design of the system?It lists the implementation details of the system and specific modules.The main work of this paper includes:It puts forward the background of the project that is the basis of system development and actual needs.Firstly,it analysis the solutions and application technology of the domestic and foreign similar demand.Secondly,it shows the technical selection and the design which are applied to the application scenario and requirements.It describes the design patterns and technical selection used in the system design and development.The technical frames are described in detail,which each includes its advantages and disadvantages and the reason why the system uses this technology.It describes the detailed design of the entire system.Firstly,the functional analysis and nofunctional analysis of the system are analyzed in the demand analysis.Secondly,the overall design and modules design of the system are described in detail.It describes the core modules of the entire system and displays the code of the core modules.Firstly,the core functions of each module are described,and the core code of each module is displayed.Secondly,some pictures of the APP surface are displayed.
