single table and root-leaf table mappings

[Rahul Mahindrakar]

Any ideas of what the above mean. I have encountered these terms in VAJ and in one of the mock exams provided by IBM.
Thanks

Hi Rahul
These terms are used when u are working with bean inheritance.
When u are using a single table in the database for mapping the fields of two beans(where one is inherited from another) , single table inheritance table map is used for schema map.
U use root leaf when bean inheritance is done in multiple level.
Hope this helps. Go thru the help of VAJ for more details. If u want any thing specific, feel free to mail me.
regards
Ram
