Dbm 380 Database Normaliztion

Database standardisation account statement Robert A. Holland DBM/380 December 11th, 2011 John Nadasky Database standardization explanation The normalization take that I chose to use for my database was the 3NF level. This level of normalization was elect because it would be liberal bounteous to add and plow data to without both complications or problems in the database.

The change! s that were made to the database were more(prenominal) on a formatting need and to identify the entities more in the database and the tables they were include in. There are no other changes that can be thought of to change the database design. Some fields could be mown and recreated to another field, but then this would vacate fields that may possibly end up being empty in the database and have no data....If you want to stomach a near essay, order it on our website: OrderCustomPaper.com
