3.3. Properties

Prev		Next

Both nodes and relationships can have properties.

Properties are key-value pairs where the key is a string. Property values can be either a primitive or an array of one primitive type. For example String, int and int[] values are valid for properties.

	Note
	`null` is not a valid property value. Nulls can instead be modeled by the absence of a key.
