The Semantics and Implementation of Inheritance in ORDBMS
This paper describes the design and implementation of inheritance mechanism in ANGEL，which is a typical ORDBMS．We lay stress on the abundance of semantics about attribute inheritance，attribute constraint inheritance，trigger inheritance and function inheritance． The resolution to different kinds of conflict and schema modification brought forth by multiple-inheritance are also discussed．
