help on structure definition

[Ing. Branislav Gerzo]

Hi!

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

'name' => {
           'ra' => {
                    'do' => undef,
                    'od' => '1996-01-07',
                    'name' => 'brano'
                    }
           'ro' => {
                    '1' => {
                            'do' => undef,
                            'od' => '1998-01-01',
                            'name' => 'john'
                            }
                    '2' => {
                            'do' => '1991-05-15',
                            'od' => '1992-11-01',
                            'name' => 'michael'
                            }
                    }
           }

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 ?

thanks.
