Abstract
The Codasyl model is a proposed specification for a Data Base System resulting from international collaboration among all interested parties, including users and manufacturers. The specification is designed to fulfil user needs, and as such it incorporates many of the user facilities discussed in the previous two chapters. As mentioned in chapter 1, the model enjoys the active support of most manufacturers, software houses, user organisations and professional organisations such as BCS, ACM and IFIP. A number of data base packages founded on the Codasyl model are already available on the market.
