This graph reminds me of the database builder in sql, where you have all the tables and you like a field of table A to a field of table B to create a unique link

It's probably similar, but infinitely more performant, because there are no tables in neo4j.
No concept of tables, just “fields” and relations between them?
Yeah, actually you can think of the data model as having exactly the same information as what's in that screenshot, heavily optimized over time since they're on version 5 now.
There are three types of data: Node labels, which are akin to tables; properties, which are like columns; and Relationship types, which are like foreign key references, but bidirectional.
Interesting
