Research On The Heterogeneous Data Storage Method For The Agricultural Internet Of Things

With the application of Internet of things,the scale of the system is also expanding,and the requirement of data storage system is higher and higher.First,with more object access to networking systems,networking data size increases,increasing the need for distributed cluster to store data;secondly,due to the complex network of different types of sensors,data are also more and more and will continue to change,not only various types of environmental data,also contains the large data files,images,and video,more and more non structured data and traditional relational data the model of coexistence.In order to solve the problem that the coexistence of structured and unstructured heterogeneous data and improve networking system in heterogeneous data storage mode of storage efficiency and reliability problems,this paper firstly,according to the different types of data in the underlying heterogeneous storage system storage efficiency were compared.Then in view of the problems existing in the process of heterogeneous data storage proposed unified storage model,it is pointed out that unified storage model data specification and data exchange should follow the points,all types of data as data object with the unified format,and according to certain rules and a bottom layer storage system for information exchange.And based on the unified data model,a unified storage platform for heterogeneous data was established.HDIP.Through the establishment of a unified storage platform for heterogeneous data,the efficient storage of massive data is solved,and the unified operation interface simplifies the user’s data model.Through the establishment of a unified data structure to achieve the unification of user data storage and retrieval;through metadata mapping mechanism to solve the mapping between the unified data objects and the underlying storage system;through the type of mapping to solve heterogeneous data storage model between the type of matching.At the end of this paper,hdip system based on later as design of data management and realize the agricultural IOT application system prototype-Daejeon IOT environment monitoring system to the practicability and validity of the verification of heterogeneous data unified storage platform will help in the future for heterogeneous data storage system application.
