Edgar (Ted) Codd,
co-founder of the relational database, died last Sunday in Florida,
according to the Mercury News:

As we all know.
Oracle used the relational mode from Codd and Date to model the Oracle
database.
Ted is survived by
his wife Sharon Codd (the mother of OLAP), four children and six
grandchildren. Sharon Codd is a famous relational theoretician in her
own right, and co-authored the 12 rules of OLAP with Ted in 1993.
This was very sad
new to those of us who were raised on Codd's rules of normalization.
Codd's most famous quote (in my opinion) was when he was asked why he chose
the word "normalization" to describe relational database modeling.
Codd was reported
to have replied "At the time, Nixon was normalizing relations with China.
I figured that if he could normalize relations, then so could I".
Ted Codd may best
be remembered for a famous mnemonic on his definition for
second-normal-form:
"A relation is
in second normal form if the relation depends on the key, the whole key, and
nothing but the key, so help me Codd".
Chris Date could
not be reached for comment.
We all extend our
deepest sympathy to his family and colleagues.
