The 78 Codasyl Database Model: A Comparison With Preceding Specifications

Summary: 78 CODASYL model vs 73/71; external DDL separated from internal DSDL, boosting data independence and explicit DDL integrity constraints. Converting 73-model databases to 78, focusing on DSDL capabilities and internal storage options for implementation. (summarized by gpt-5-nano on Feb 09 2026)
