I wonder if someone can tell me a way of building a hierarchy in a database. Like when I build levels in a wordprocessor like 1.1, 1.2, 1.2.1 etc. The purpose should be to put articles in a table and keep track of article groups. The problem is (as I can see) the levels are not fix, eg one article can be on level two, say 1.1.1 and another one can be on level three say article 1.2.3.1, that is the first article of level 1.2.3.
Am I putting myself clear enough?
