Embodiment

[0041] figure 1 It shows a flow chart of a graph database creation and data loading method provided by an embodiment of the present invention; figure 1 As shown, a graph database creation and data loading method provided in this embodiment includes:

[0042] Step S1, receiving the source file data input by the user, the source file data is structured data, converting the source file data into csv format or tsv format, and displaying the format-converted file data through a visual interface;

[0043] Step S2, acquiring the node selected by the user in the format-converted file data through a visual interface, and correspondingly selecting node attributes for the node;

[0044] Step S3, obtaining the edge selected by the user through the visual interface in the format-converted file data, wherein the edge includes at least two selected nodes;

[0045] Step S4, selecting two nodes from the nodes included in the edge as the start point and end point of the edge, and selecting ed...

Abstract

The invention provides a picture database creating and data loading method and equipment and a medium. The method comprises the steps of receiving structured data source file data input by a user, andconverting the source file data into a csv format or a tsv format; obtaining nodes selected from the file data obtained after format conversion, and selecting node attributes for the nodes; obtainingedges selected from the file data obtained after format conversion, wherein the edges at least include two selected nodes; selecting two nodes from the nodes contained in the edges as the initial node and the terminal node of the edges, and selecting edge attributes for the edges; transmitting the nodes, the edges, the node attributes corresponding to the nodes and the edge attributes corresponding to the edges to a server, creating picture data, and storing the data into a picture database. By arranging a visual interface, a user can perform picture modeling on the basis of the common sourcefile data through the simple process, and import pictures into the picture database, the existing complex picture building process is greatly simplified, convenience of easy dragging is achieved, andthe processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to the fields of graph database creation and data loading methods, equipment and media. Background technique [0002] Now graph database (graph database) is becoming more and more popular. People mainly use graph database to support knowledge graph and portrait applications. In graph database, data is stored and operated according to the mode of "node" and "edge", which is the most direct An example of a graph is a social network, where each person is a node and the edges are friend relationships. The world's three largest open source graph databases are Neo4j, Titan, and Orientdb. To use these graph databases, you must first establish graph structure data and import it into the library through operations such as data modeling, transformation, and import based on non-graph structure data sources through a certain process. [0003] If the data source is a csv file, the data must be loaded ...
