A method is proposed to achieve seamless integration of DBMS functionality with application code using inheritance. The language must provide 1) multiple inheritance , allowing the objects to be stored in the database to inherit the necessary methods, and 2) genericity , in order to document what...
When a class inherits from more than one base class, you have multiple inheritance. The extent to which multiple inheritance is supported in programming languages and DBMSs varies considerably from one product to another.

In most object-oriented data models objects must belong to a single most specific class. This exclusive link between an instance and a class is often not adequate to model real-world situations. In this paper, we present an approach where objects can bel
