[Beankeeper-discussion] unique "keys "

[Shay M. <mat...@gm...>]

Hi ,

my sample app has a company data object and a user data object, i would 
like usernames to be unique, across the board.

i assume that maintaining this uniqueness per company is done via the 
collection container of the company ( Set<user> company users)

how do i make sure that usernames are unique across companies(the 
parallel of unique property on a DB column), do i have to run a GetName 
query before each user addition?

thanks,
Shay
