Can anyone tell me what the 'restrictions' actually are?

The whole article is outdated, but I lack the editorial skill/technological knowledge to fix it. Rails has marvelous tools for generating hierarchical databases in a relational context, and then using the flexibility of Ruby easily represent the db. NoSQL has also raised the issue of database architecture in new ways. I almost feel like the article should start from scratch, and then hope that people mod into into currency (rather than throwing up their hands at its series of missteps) <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/24.14.168.220|24.14.168.220]] ([[User talk:24.14.168.220|talk]]) 15:43, 6 October 2013 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->
==Bad example==
Line 61 ⟶ 62:
The example also uses bad logic. Logically, a child has at least two parents (biologically) and those two parents could potentially work for the same company. Creating duplicate entries in the Child table would be less effective. I thought hierarchical referred more to a subclass/superclass relationship; e.g. the relationship between person and employee.
