Single value identifies a property that has only one value. An example of a single value property is Name if only one name, with multiple words, is allowed. multi-value properties can have more than one value. For example, if the property is Borrowers and more than one borrower is listed, the property should be a list. The property Author should be a list because a book can have more than one author.
NOTE Multi-valued properties use more space in the system. Individual items within a multi-value property are selectable in a query.
