Hello Friends,
I am using berkeley-DB for my work. As you might know berkeley-db
allows variable length records to be inserted.
The problem is,
I need to draw an ER diagram for the same, so the issue is
* in an ER diagram how do i show my optional attributes ??*
Let me give you an example:-
say i have 5 attributes regularly but if i get a specific header i
have to add some additional attributes with the previous 5 and then
insert the whole record in the database.
Any Links will be helpful !
Thanks in advance !
Rohan Dighe.
