I’ve been reading about OrientDB for a while now, and I’m a bit confused about the “Editions” of the software.
The main version sounds like it’s just the document store, but things on the internet make it sound like it’s both the document and graph database. http://nosql.mypopescu.com/post/1254869909/correction-orientdb-is-a-document-and-graph-store
What is the difference between that and the graph edition?
Does the graph edition just do graphing with nodes and edges, or is it the document graph database?
Update: What is the key value store version? How does it differ? Can you use alongside the other editions?
OrientDB is a document-graph dbms because has the document-db features but handles relationships using direct links, not with JOINS like RDBMS.
So you can use the standard version to map even a graph. The Graph Edition is the Standard one with bundled the TinkerPop technology stack like the Gremlin language.
