Objects Facts

There are a number of alternatives for mapping Objects onto Tables :-

Store everything in one table
Create one table per class and one SQL view per superclass/subclass relationship
Create one table per subclass (in the case of inheritance that includes superclass attributes as well)

Each alternative has different Performance implications which need to be evaluated for any specific situation.
The aspect of Mapping is discussed in more detail elsewhere.
