Re: [Wil] slashdot.org : With XML, is the Time Right for Hierarchical DBs?

My understanding is that there are no or limited joining of tables in hierarchial systems, which is a drawback in terms of data processing in Relational systems where you end up joining two tables minimal to connect primary and foreign keys, and even more if you have superkeys.

The major drawback of hierarchial systems, IMO, is setting and maintaining referential integrity, which is very easy to do in relational systems.
