Design And Implementation Of Data Fusion System Based On Map Details

With the development of the times,Internet map has become an indispensable tool for people's daily travel.In the process of using Internet map,as the core data of location-based services,POI(Position of Interest)data's importance is self-evident.POI data is divided into two parts,basic data and detailed data.Moreover,POI detailed data is the core channel to provide a large number of extended services to users.At present,the POI details in the Internet map can meet the core needs of users to a certain extent,but their quality is generally low and quantity is lack,because they cannot make good use of the multi-source and heterogeneous POI detail related data in reality.Therefore,we need a data fusion system that can make full use of the multi-source and heterogeneity data,then integrate them and produce more high-quality and comprehensive data.Finally,the POI detailed data will be presented on the Internet map to provide good experience for users.The data fusion system based on map details will focus on processing,storage,fusion and updating of the stream data.It designs the core process between the POI details collection and practical usage.The high-quality POI details based on the multi-source and heterogeneous data will be produced in real-time.In order to facilitate maintenance and redevelopment,this project will be developed based on the mainstream technique,more specifically,Linux system.PHP language will be used to complete the functions of data process,data store,data fuse and data update.At the end,the high-quality and comprehensive POI details will be persisted for all downstream services.In the process of research and development in this project,I mainly responsible for universal service framework,data process service,data storage service,data fusion service and data bank service.The Swoole framework is used in the project,and the architecture is designed follow the high expansibility and high performance.Finally,the micro service architecture is applied,each service is combined as a small service and construct the whole system.This project has been finished and as a core component in POI data system,providing data support for other downstream systems and providing services to hundreds of millions of users.
