Emanuele Tagliaferri discusses graphs and OrientDB. He defines vertices/nodes and edges/relations in graphs and how data can be associated with nodes and relationships. Graphs are good for linked, complex data but not for flat, unlinked data. Common operations on graphs include pattern matching to search for patterns of nodes and relationships and traversing relationships to flatten graphs or perform counts and aggregations. OrientDB supports graphs with object-oriented and document concepts and is transactional and operational, including standard graph algorithms.
