Hello. Question 1: You'll just embed another document (or vertex) in the contact property. Are you trying to do this from the Java API?
Question 2: Once the original database is shutdown, you can just copy the database folder to a new name. Even if you decide to use the 'document' approach, you don't need to do anything else. The two mix easily together as well. Question 3: Sure. You could create a cluster per politician classification. What's the intended purpose? Another idea is that you could create a base Politician class and then create specialty derived classes that extend Politician. Each derived class will use its own cluster by default. Hope that helps. -Colin Colin Leister Orient Technologies The Company behind OrientDB On Sunday, March 1, 2015 at 9:07:26 PM UTC-6, Kiheung Park wrote: > > Hi, > > I want to create a database in which can hold agent's information such as > politician records.
