==History== The network model's original inventor was [[Charles Bachman]], and it was developed into a standard specification published in 1969 by the Conference on Data Systems Languages ([[CODASYL]]) Consortium. This was followed by a second publication in 1971, which became the basis for most implementations. Subsequent work continued into the early 1980s, culminating in an [[International Organization for Standardization|ISO]] specification, but this had little influence on products. Bachman's influence is recognized in the term [[Data structure diagram#Bachman diagram|'''Bachman diagram''']], a diagrammatic notation that represents a database schema expressed using the network model. In a Bachman diagram, named rectangles represent record types, and arrows represent one-to-many relationship types between records (CODASYL set types).
