The Network Data Model
Date: Wed, 21 Apr 2004 14:31:28 -0400
In looking up the history of the "hierarchical and network data models", I followed the "network data model" track. After all, Codd mentions the network data model in his classic ACM article of June 1970.
The trail led back to Charles Bachman, and GE IDS. In 1963. Here's alink.
It's possible that the term "network data model" came into vogue earlier than the term "hierarchical data model".
The use of trees or hierarchies to structure data goes back to the 1950s, when John McCarthy invented LISP, and possible beyond. Received on Wed Apr 21 2004 - 20:31:28 CEST
