Network resources are the data core of OSS domain of telecom operation support system. With the rapid development of telecom industry in recent decades, it has entered the era of big data due to the accumulation of a large amount of data. However, due to the imperfect resource management mechanism, network failure, cutover, complexity of resource relationship itself, human and other factors, the volume of problem data is getting larger and larger. Through big data technology, this paper builds a distributed database cluster based on greenplum, and proposes a verification tool to improve data quality from multiple perspectives such as cluster design, functional architecture, data mart, running timing, and rules, so as to realize big data governance of network resources.
