The relational data model was first developed by Dr. E. F. Codd, an IBM  researc

The relational data model was first developed by Dr. E. F. Codd, an IBM  researcher, in 1970. Dr. Codd published a list of 12 rules defining the  ideal relational database in 1985. Perform an Internet search on the  rules and define how these rules play a role in current relational  databases. The summary without the references should be at least 200  words. Make sure to include a citation and list the reference in APA  format. 
It is amazing how rapidly database technology has evolved and how  pervasive database use has become. Identify a modern business in which  databases are used and provide examples on how these databases are used.
For example, in healthcare databases are used to track the typical  human resource areas, such as salaries and benefits; to track patient  from registration all patient activity during a visit or stay; analyze  activity at the hospital, etc.
