Default Value

i have a table ,  Suppliers(id , name , website , .... , default_value) 

id , name , ..... , default_value

--------------------------------------

1 , jack , ........., 1

2 , joe , ..........,

3 , matt , .......,

- the supplier which his default value = 1 is the default supplier for purchasing orders i.e .

- may be i have hundreds of suppliers .

- may be i have many tables needs a value in a row to be the default value .

- is it right to design each table like that , include the column(default_value) for it ?

- can not i create only 1 table for the whole system , and name it  default_valueS(default_supplier , default_customer , default_currency,....etc) ?

- is there a better way to handle this situation ?

- i think this community is for " systems analysis and design " questions ? if not , then please provide me with a link for a popular community for that .

thank you so much
