I don't know if Valentina has optimzed algorithms to traverse such a graph and about the performance when using many records (objects) with many links to many other objects.
Well, I think our BINARY LINKS, and our feature todo Recursive Searches on any levels down, up, side, are so powerful, that not doubts here
Our BinaryLinks work faster than Relational ULONG - ULONG link based on PK-FK
Right?
And I always was and I am skeptical to KeyValue Storage as UNIVERSAL storage, to keep complex structures.
And I always was and I am skeptical to MongoDB, which keep data in TEXTUAL format of JSON. This can be faster of direct pointers?
Mongo have some win for special tasks, when one user have data, separate from data of other user. So they can scale to hardware. But excuse me, such scale you perfectly and easy can do with RDBMS (postgreSQL, mySQL, MS SQL, VDB).
Format of some file, such as JSON or XML, cannot be base of DB. Remember in about 2000 year how many noise was about XML-based databases, and how they will kill relational. Three times HA HA HA
Where XML dbs today?
I think the same story expects the "JSON-boom".
Relational DBs will add COLOMN of JSON type, as some did with XML type, and that is enough.
XML/JSON - are text formats, perfectly can be used for
exchange of data
BETWEEN DBs, DB and user, ...
