Discussion Subject:" Change of Codd's RDBMS Rule after research "

Dear Sir,

Myself, Shekhar P. Sinha, have found that

in " RDBMS-Oracle according to Codd's Rule only a single

primary key can be defined in a single table " but " I have

found that " I can define more than one primary key

in RDBMS-Oracle single table" and this was successfully done

on 4th of July, Saturday, 2009

I would like to have your suggestion.

Thanking you Sir,

with regards,

Shekhar P. Sinha,iFuture College of Technology and
