alarm correlation analysis method based on a graph data model

The invention discloses an alarm correlation analysis method based on a graph data model. The alarm correlation analysis method comprises the following steps: step 1, constructing the graph data model: converting a relational database model into the graph data model; Step 2,performing fault marking: when a network fault event or a user complaint event is received, marking a corresponding node inthe graph data model as a fault; Step 3, performing alarm pre-association: taking out the node with the lowest hierarchy from the graph data according to a fault time window, and storing the node in apre-association result set; Step 4, carrying out root alarm association judgment to determine a fault root source: in a pre-association result, when a further association relationship does not exist,determining the corresponding node as the fault root source; And when the further association relationship exists, the node involved in the association relationship is the fault source. According tothe method, the relation mode
