The invention provides a graph data access method and system. The graph data access method comprises the steps of dividing graph data information to be stored into side data information and top point data information, wherein the side data information includes top point identifiers connected with the sides, the top point data information includes one or more top point attribute information, the top point attribute information includes positioning information of attribute data and positioning information of top point attribute analysis information, the positioning information of the top point attribute analysis information is used for determining positions of the top point attribute data, and the positioning information of the top point attribute analysis information is used for determining positions of the top point attribute analysis information; respectively storing the side data information and the top point data information. The top point attribute analysis information is used for analyzing the top point attribute data so as to obtain values of top point attributes. The top point attribute analysis information includes top point attribute types and valuing modes of the top point attributes in the top point attribute data. By means of the technical scheme, the graph data access efficiency can be improved.
Description
technical field [0001] The invention relates to a computer technology, in particular to a graph data access method and system. Background technique [0002] Graph is the most commonly used type of abstract data structure in computer science. It is more complex than linear tables and trees in terms of structure and semantics, and has more general representation capabilities in terms of data and data relationships. Although the application and processing technology of graphs have been developed for a long time, with the continuous growth of information scale, the scale of graphs is increasing, and how to efficiently process large-scale graphs has become a new challenge. At present, the storage and processing of large-scale graphs in the cloud computing environment has advantages. Graph storage systems based on cloud computing environments can be roughly divided into two types: one is a distributed file system represented by GFS and HDFS; the other is a NoSQL distributed datab...
