If a Vertex Is Deleted, What Will Happen to Edges Formed Based on the Vertex?

GES imports graph data based on the property graph. A property graph is a directed graph consisting of vertices, edges, labels, and properties.

A vertex is also called a node, and an edge is also called a relationship. Nodes and relationships are the most important entities.

  • Vertices in the data model represent entities, such as vehicles on the transportation grid, sites on a communications network, users and products on an e-commerce network, and web pages on the Internet.
  • Edges in the data model represent relationships, such as friend relationships on a social network, user ratings and purchasing behavior on an e-commerce network, cooperative relationships between authors of a paper, and index relationships between articles.

If a vertex is deleted, edges formed based on the vertex are automatically deleted as well.
