I am looking information about:
What do you mean by "graph database"?
I believe Edirlei is looking at a database has tables of nodes/points/vertices with attributes (eg. X, Y, name) and edges/lines with attributes (eg. distance, direction). Edges have a start & finish node which refers to items in the nodes table. This type of database can be implemented in Oracle & SAP HANA to name a few.
If anybody has any information, I would love to hear about it to
Anthony, thanks for clarifying. What you mentioned is what my question refers to.
