CIS223 Database I Unit 3 Assignment 1: Chapter 6, pg. 213 Questions 1-5 pg. 271 Problem 5 a-c Chapter 6, pg. 213 (1-5) 1. What is normalization? Normalization is a process for evaluating and correcting table structures to minimize data redundancies, thereby reducing the likelihood of data anomalies. 2. When is a table in 1NF? The term first normal form (1NF) describes the tabular format in which all of the key attributes are defined, there are no repeating groups in the table (In other words, each row/column intersection contains one and only one value, not a set of values), and all attributes are dependent on the primary key. 3. When is a table in 2NF? A table is in second normal form (2NF) when it is in 1NF and it includes no partial dependencies; that is, no attribute is dependent on only a portion of the primary key. It is still possible for a table in 2NF to exhibit transitive dependency; that is, the primary ...
