Kevin, Orient has Classes which can be either a vertex or an edge if you want to use graph approach or you can just create a class which is the same a document collection.
These classes are like documents in Mongo and can be schemaless. The studio is great to quickly create your data models. create class Person Extends V -------> Like db.Person in Mongo To insert there are a few options but one way is to use create vertex Person set Name = "Bill" , Height="1.66" A vertex is like a row or record and an Edge is a relationship that can joins rows. Mongo has no concept like this. The only way is to embed data as subdocuments. Which results in many problems. You really have to do a lot of schema design to support querying up front. The great thing with Orient are that records are first class citizen which means that they are links rather than traditional joins. The data that has a relationship points to each other. I'm just new to Orient myself and have replaced my entire data layer in a matter of weeks. It has opened up new possibilities. Regards, Tom On Tuesday, 25 March 2014 16:47:29 UTC, Kevin K.
