Graph database vertices and edges
Edges link two vertices in the database. The vertices must exist already. To create a new edge in the current Graph Database, call the Edge OrientGraph.addEdge(Object id, Vertex outVertex, Vertex inVertex, String label )method. Bear in mind that OrientDB ignores the id parameter, given that it assigns a unique ID when it … See more To create a new vertex in the current Graph Database instance, call the Vertex OrientGraph.addVertex(Object id) method. Note that this ignores the id parameter, given that the OrientDB implementation assigns a unique ID … See more Vertices and Edges can have multiple properties.
