Abstract

The application discloses a method for retrieving node data in a graphic database, and the method comprises the following steps: defining a path description relation between nodes in the graphic database; getting a source node which needs to perform data retrieval and a target node related with the source node; determining a path expression of a path where the source node and the target node are located according to the path description relation; and sequentially performing the data retrieval on the source node, the target node and related nodes between the source node and the target node in the path expression. In the method for retrieving the node data in the graphic database, data information of the source node and the other nodes related with the source node can be directly got by determining the path expression of the path at which the node needing the retrieval in the graphic database is located and sequentially performing the data retrieval on all the nodes contained in the path expression.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a method and system for retrieving node data of a graph database. Background technique [0002] A graph database is a data set that uses a computer to store the basic elements of points, lines, and graphs in a certain data combination, and describes the graphs in maps and other types of planes as basic elements such as points, lines, and planes. These graphical elements are data collections established according to a certain data structure (usually a topological data structure). [0003] The architecture of the graph database can be divided into three layers from top to bottom. The top layer is the organization and realization of various conceptual objects in the graph data; the middle layer is the abstract physical data storage interface, which abstracts the physically stored data into several DataSets. ; The bottom layer is the physical storage implementation layer, wh...
