Research On One-card Heterogeneous Data Integration In Big Data Age

With the emergence of internet of things, cloud computing and other newtechnology and rapid development, the data quantity rapid growth, the world into theera of "big data". Use of information and communication technology to sense, analyzeand integrate the core city operations critical information systems, and thus the city inresponse to a variety of activities to make intelligent "smart city" has been proposed,hoping to ease the development of modern cities encountered as environmentalpollution, traffic congestion, confusion, and many other security problems."City Card" is part of the realization of "smart city" construction. With the recentchange of information technology continues to improve,"City Card" has gone beyondthe realm of public transport modes based legacy applications, cross-sectored, inter-regional and multi-domain applications to achieve interoperability become the maindirection of development. How many applications in the field of IC card dataintegration, to provide users with more quick service become a prerequisite for "smartcity".In the new environment with a large amount of data card data, the data structure isnot fixed, the value of the sparse data, such as the obvious big data characteristics. Thispaper analyzes the characteristics of the "smart city" and one-card data proposed "CityCard" big data architecture platform based on big data. Use of non-relational databasesto solve the problem of heterogeneous data stored in the data layer. In the logical layerof middleware model using logical integration of heterogeneous data Provide intelligentrecommendations and decision support services to users based on user behavior andcharacteristics of real-time environmental information. Solutions presented in this paperto solve the problem of multi-purpose card heterogeneous data in the era of big dataprovide a new train of thought.
