A CMDB
system based on a graphic data base comprises a relational data base, the graphic data base, a
data mapping module, a
correlation analysis module and a CMDB query module, wherein the relational data base is a data storage module in an original CMDB; the
data mapping module is used for mapping
configuration item instance data in the relational data base into the graphic data base; the
correlation analysis module is used for obtaining a
configuration item instance set related to a query condition from the graphic data base; the CMDB query module is used for querying detail
analysis data corresponding to specific
configuration item instances from the relational data base. By the utilization of the characteristic of consistency between the relation between the configuration item instances and a graphic
data structure, the specific configuration items and the relation are mapped into a graphic data base structure, so that complex
query analysis calculation is converted to relatively simple graphic
traverse analysis calculation, the
system logic is simplified, and the
enforcement efficiency of the
system is improved. Meanwhile, the graphic data base optimizes storage and query of the graphic
data structure, so that the
execution time of correlation query is shortened.
