Research And Application Of Web(Database)and Heterogeneous Multi-Client Push Technology

Internet of Things is a new revolution in the industry.With the development of Internet technology,it brings great convenience to people's production and living,and it is still growing rapidly.In the Internet of Things,various types of intelligent terminals generate or receive a large amount of information every day.However,most current small and medium-sized enterprises are unable to meet the storage requirements of massive information using traditional relational databases.At the same time,how to get the information they need from the massive information become the focus of people's attention.This article first compares current mainstream relational and non-relational databases and then compares the various push techniques.Then according to the storage requirements of massive information and the characteristics of demand under the Internet of Things environment,the data is stored in a non-relational MongoDB database for document selection.The MQTT protocol is selected for message transmission.The protocol is designed for remote sensors and control devices operating in low-bandwidth,unreliable networks,to achieve the development of the message push system.Subsequently,the subject completed the system requirements analysis,the overall system architecture design,system design of various functional modules,and developed a set of message push system,and in the flower basket platform for functional and performance comparison test.Finally,a set of message pushing system that can help small and medium-sized enterprises to adapt to complex mobile network scenarios with high concurrency,low flow,low power consumption and heterogeneous multi-client systems is completed.The system uses open source software and has the advantages of low cost and high efficiency,Implementation of the deployment of convenience,can better meet the needs of enterprises and users.
