Journal of Networking Technology Yong-qiang HE, Xue-rui WANG 10 3 2019 https://doi.org/10.6025/jnt/2019/10/3/87-91 http://www.dline.info/jnt/fulltext/v10n3/jntv10n3_3.pdf In today’s society, the internet was increasingly expanding the scale of the computer network, the structure of the network has become more and more complex, the network management system must have a higher intelligence. A large amount of data had been processed in the network management system, and the application rules on data processing are the two most basic elements, and the database had provided a technical solution to achieve the function of these basic elements. This paper discussed the network management system, the basic function of network protocols and network management MIB databases, the ERC plus method of database design are discussed, and the application example is given. The article also analyzed the adaptability of network management application on database. The design and maintenance of the network system is very useful.
