Consider multiple relational database schemas that have an inheritance dependency structure as known from OOP systems:
Tables are just a placeholder for arbitrary database objects such as Views, Stored Procedures, etc.
Are there any methods or tools that might help me express this abstraction? Such as a package manager that builds modular create and upgrade scripts?
(I am not talking of O/R Mapping within one database schema. Actually I am primarily thinking about an BI application, so there is no ORM anyway.)
