ICHABOD

摘要

ICHABOD, a practical and easily implementable data base manager for Design Automation applications, is described. It is based on key aspects from both the network and relational data models. The user primitives and utilities support open-ended dynamic data structure definition and provide efficient data access mechanisms. Implementation techniques for the physical file structure and memory management are presented. ICHABOD has been successfully incorporated into two Honeywell production Design Automation Systems.
