Abstract

The invention discloses a data read-write method, device and equipment of a graph database and a storage medium, graph instances created based on the graph database comprise pattern graph instances and pattern-free graph instances, the method comprises the steps that to-be-written data is acquired, and the to-be-written data is point data or edge data; the method comprises the following steps: in a mode scene, obtaining a first label to which to-be-written data specified by a user belongs, each first label corresponding to a predetermined attribute set, and each attribute in the attribute set comprising an attribute name, a data type and / or a constraint; to-be-written data and values of attributes of the to-be-written data are written, and the values of the attributes comprise values corresponding to all the attributes in the attribute set and meet the corresponding data types and / or constraints; and writing the to-be-written data and the attributes and the corresponding values of the to-be-written data in the mode-free scene. According to the technical scheme provided by the invention, the graph database can support the pattern graph instances and the pattern-free graph instances at the same time.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a data reading and writing method, device, equipment and storage medium of a graph database. Background technique [0002] With the explosive development of the Internet, mobile Internet, social network, Internet of Things and related networks in the industrial field, such as power networks, there is a great demand for applications such as relational graph storage and network topology analysis and function analysis based on relational graphs. At the same time, it also contributed to the research and development boom of graph database. [0003] The traditional relational database can respond stably in real time in the face of On-Line Transaction Processing (OLTP) requirements. For example, in the online shopping mall's user purchase behavior records, the system will record who, when, and when the purchase behavior occurs. Which store bought what, such behavior data will b...
