Quotes and Comments on Database Systems
It was thirty years ago today
Dr. Edgar showed the world the
way
- with apologies to Lennon & McCartney (from
C.J. Date)
Dr. Edgar F. Codd is the father of the Relational Model which he
introducted to the world in 1969. The major contribution was to make
database management into a science. Codd provided a theoretical
framework for data. The term Relational Theory is as appropriate as the
Relational Model.
Paraphrased from C. J. Date
Data that is 99.9% pure is
0.1% impure. That means that 1 in 1000 pieces of data is bad. There is
NO room in a database for bad data. It is the database developer's job
(your job) to ensure that no bad data can enter and corrupt the
database. Remember that the bad piece of data might just be used to
calculate your pay check!
We lost much on 9-11 but we
did not lose data. Many data intensive cooperations had major offices
in the Twin Towers and they lost all of their computer equipment but,
because of database management systems, they did not lose their data.
