(Azure Cosmos DB) Edges in Graph DB Require two vertices.
The correct option is: "Require two vertices."
Here is a brief explanation of the requirements for edges in a graph database:
- Edges represent relationships between vertices (also known as nodes) in a graph database.
- Edges require two vertices to exist, as they connect two vertices in the graph.
- Edges can have properties associated with them, but it is not required.
- It's important to note that the requirements for edges in a graph database can vary depending on the specific implementation being used. However, the general requirement for edges in a graph database is that they must connect two vertices. The other two options ("Require properties" and "Are mandatory") are not accurate.
Here are the requirements for edges in a graph database in more detail:
- Connect two vertices: Edges in a graph database represent relationships between vertices. An edge must connect two vertices in the graph in order to represent this relationship.
- Optionally have properties: Edges can have properties associated with them, which can be used to store additional information about the relationship represented by the edge. However, it is not required for edges to have properties.
- Not required to be mandatory: Edges are not required to be mandatory in a graph database. This means that it is possible for a vertex to exist without any edges connected to it.
Therefore, The correct option is: "Require two vertices."

In Graph DB, edges call for two vertices.
"Require two vertices" is the right response.
An overview of a graph database's needs for edges is provided below:
In a graph database, edges represent connections between vertices, also referred to as nodes.
Since edges join two vertices in a graph, they necessitate the existence of two vertices.
Although it is not necessary, edges may be associated with certain properties.
It's crucial to remember that depending on the particular implementation being used, the specifications for edges in a graph database can change. However, in a graph database, an edge must generally connect two vertices in order to be considered an edge. The second and third choices, "Require properties" and "Are necessary," are incorrect.
More specifically, the prerequisites for edges in a graph database are as follows:
Join two vertices together: In a graph database, edges show connections between vertices. The relationship must be represented by an edge joining two vertices in the graph.
possess potential attributes: In order to preserve more details about the relationship that an edge represents, edges may also have attributes attached to them. Edges do not necessarily need to have attributes though.
Not necessary to be required: A graph database does not have to make edges obligatory. This implies that a vertex can exist even if it is not connected to any edges.
Therefore, "Require two vertices" is the appropriate response.
