Normalization of the ERD By: Vanessa Kennedy Normalization of the ERD The normalization of the ERD along with the driver’s log is taking all of the data within the database and putting the information into tables (World Book‚ 2011). In addition‚ after the data is normalized it then is put into an Entity Relationship Diagram or ERD (World Book‚ 2011). In this paper we will look at the ERD of the driver’s log. The normalization that I would perform on the driver’s log would be on the Driver’s

ERD Explanation DBM/380 January 23‚ 2012 ERD Explanation There are several levels of normalization such as 1NF‚ 2NF‚ and 3NF. The Huffman Driver database was brought to the normalization level of 3NF by following a series of guidelines from the lowest form of normalization‚ 1NF. The first normalization form level (1NF) consists of the basic rules for an organized database. These are: • Eliminate duplicative columns from the same table. • Create separate tables for each group

Difference Between ERD and DFD ERD and DFD are data presentation models that help in identifying the flow of data as well as inputs and outputs. They are important as they enable effective communication between members of different departments in an organization. There are similarities in the two types of data presentation models although there are differences that will be talked about in this article. DFD’s are systematic representation of how data flows in an organization‚ how and from where
