Modeling And Management System Design Of Power Communication Network Operation And Maintenance Metadata

In recent years,The level of informatization of power communication network operations and maintenance has been continuously improved.Power companies have built many operations and maintenance management systems to support the growing business of power communication networks.The professional and sub-function operations and maintenance management system generates a large amount of operations and maintenance data.In order to better manage the operations and maintenance data of the power communication network and fully exploit the value contained in the operations and maintenance data,it is necessary to construct a power communication network operations and maintenance data warehouse to centrally store and manage the operations and maintenance data of the power communication network.To this end,it is necessary to uniformly model the operations and maintenance metadata of the power communication network,and introduce a metadata management method to build a power communication network operations and maintenance metadata data management platform,lays the foundation of building a unified and highly integrated data warehouse,achieve complete,accurate and consistent data management.This paper first introduces the basic knowledge of data warehouse and metadata,discusses the importance of the unified operations and maintenance metadata model and metadata management,and then discusses the system source of operations and maintenance data of power communication network,and divides the operations and maintenance data into six subject domains for network planning metadata,network resource metadata,business metadata,network behavior metadata,operations and maintenance management process metadata,network planning design metadata,and supplier metadata.And then analyze operations and maintenance metadata according to different subject domains,then build metadata model.In the end this paper discussed the problems that need to be solved in the operations and maintenance of the power communication network metadata management.Then designed the functional modules and technical architecture of the operations and maintenance metadata management system.Hierar-chically,the function realization of the core module is designed and implemented.
