Difference between creating a property or a link

I am a newbie at orient-db. I am currently using 1.5.1, but will upgrade to 1.6 shortly.

I've seen two examples of creating a link between two classes, where class A has a 1:N relationship with class B.

One was via the CREATE LINK command, and the other was using the CREATE PROPERTY LINKSET on class A.

What are the differences between these two methods? Which one should I use?

Solution

  • Link is one cardinality, linkset is multiple cardinality. Look at the documentation: https://github.com/orientechnologies/orientdb/wiki/Concepts#relationships
