You cannot make a foreign key to link two different tables with RDBMSes. It requires to make another table. With graphs instead this is easy, just make a link from/to any node. With RDBMSes the schema is fixed. With RDBMSes you cannot have "metaproperties" (or properties about properties). With graphs you can easily say {caesar born{source "foobar"} "100BC"}. With RDBMSes this quickly becomes a mess to handle when you have more properties.

These are just some use cases why relational does not always win.
