SFAIK[edit]

I work with DMSII and as far as I know its a network schema database. Obviously it can emule a hierarchical schema or a relational one. In this case without the powerfull relational operators. The link below confirm the characteristics of DMSII.

Hierarchial?[edit]

I remember being DMS II being relational, but it would make sense for it to at least originally to have been hierarchial as hierarchial packages such as IMS and FOCUS were dominant when it was first created and distributed.Lycurgus 12:23, 27 July 2007 (UTC)

Also removed the link:

since it is apparently dead. If it is in fact an ACM doc may be able to restore later Lycurgus 12:44, 27 July 2007 (UTC)

Current text makes it more or less clear that it is a network-relational hybrid. 72.228.177.92 (talk) 09:20, 15 May 2010 (UTC)
Link above no longer dead but it is just a list with a mention of DMS II nothing of substance at all. 72.228.177.92 (talk) 09:23, 15 May 2010 (UTC)
So looks like I reversed above. DASDL actually was a mix of network and hierarchial, I think, maybe a distinctive thing, calling it straight network model as the source does seems wrong. 72.228.189.184 (talk) 00:42, 28 July 2012 (UTC)

What does "modek" mean?[edit]

The first paragraph ends, "The original DMS II used a network modek.[1]" Maybe modek is an obscure comp sci word I've never heard of, but I suspect it's a typo for "model". If you concur, please fix it, thanx. — Preceding unsigned comment added by 70.181.124.207 (talk) 15:33, 27 February 2013 (UTC)
