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

Reason for {{Cleanup}}

The text doesn't reflect the lemma: Hierarchical model should describe the logical elements only, but the introduction for example talks about database management systems. --S.K. 17:39, 24 Jun 2005 (UTC)

Agreed - for definite the current 'definition' includes elements that are clearly descriptions of relational database models, rather than hierarchical models, and are therefore inaccurate/incorrect. Unfortunately I don't have a complete and reliable alternative definition for you.

Also - Isn't Adabas a relational database?

LDAP

Is LDAP considered to follow the hierarchical model?

From the LDAP article:

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.
