[Hibernate-devel] The beauty of multiple tables in polymorphic persistency?

[Roman S. <hib...@gr...>]

Hi!

I´ve been thinking of extending Hibernate to allow for a seperate table 
for subclasses. I allready developed a test case when i was on holliday 
last week. I would extend the mapping file with a possible table 
property in the subclass element that would allow the additional 
properties of this class to be mapped to another table.

Is it a performance benefit to map to multiple tables? If not it might 
be useless anyway - might depend on the database...

cheers
