Can anyone tell me what the 'restrictions' actually are?
Line 27 ⟶ 25:
''LDAP directory entries feature a hierarchical structure that reflects political, geographic, and/or organizational boundaries. In the original X.500 model, entries representing countries appear at the top of the tree; below them come entries representing states or national organizations. Typical LDAP deployments use DNS names for structuring the top levels of the hierarchy. Further below might appear entries representing people, organizational units, printers, documents, or just about anything else.''
Yes, definitely LDAP is hierarchical. So is DNS. In fact, DNS, LDAP, and common filesystems are by far the most widely used hierarchical databases. The topic's claim that IMS and Windows Registry are the most common is laughable. <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/140.90.235.252|140.90.235.252]] ([[User talk:140.90.235.252|talk]]) 23:06, 28 July 2011 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

The whole article is outdated, but I lack the editorial skill/technological knowledge to fix it.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==
Remove the disgusting example of a company keeping track of their employees chilren, unless you specify that the company in the example is comitting a crime. <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/85.225.210.121|85.225.210.121]] ([[User talk:85.225.210.121|talk]]) 08:12, 22 May 2009 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->
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.
