hbm2ddl

I really want to know more about the update, export and the values that could be given to hbm2ddl.auto.
I need to know when to use the update and when not? And what is the alternative?

These are changes that could happen over DB:

New tables
new columns in old tables
columns deleted
data type of a column changed
a type of a column changed it attributes
tables have been dropped
values of a column has changed

In each case what is the best solution?
