Hi!
I am thinking about best hash structure, I want save all datas from
hash to database. Example:

Explanation:
elements in 'ra' are always 1 times in hash, elements in 'ro'
should be zero or more times. Do you think this is good way how to
declare hash ?
It depends a lot on how you are using it, but...
In 'ro', is there a particular reason your using numbers 1, 2, ... as 
keys? If there is not, I'd use an array. Something like:

'name' => {
           'ra' => {
                    'do' => undef,
                    'od' => '1996-01-07',
                    'name' => 'brano'
                    },
           'ro' => [   # an array of hashes
                    {  # this was {name}{ro}{1}, now it's {name}{ro}[0]
                     'do' => undef,
                     'od' => '1998-01-01',
                     'name' => 'john'
                    },
                    {
                     'do' => '1991-05-15',
                     'od' => '1992-11-01',
                     'name' => 'michael'
                    }
                   ]
           }
