NORMALIZATION TUTORIAL (EXTRA) 1. Given the dependency diagram‚ answer items a-c: [pic] a. Identify and discuss each of the indicated dependencies. C1 ( C2 represents a partial dependency‚ because C2 depends only on C1‚ rather than on the entire primary key composed of C1 and C3. C4 ( C5 represents a transitive dependency‚ because C5 depends on an attribute (C4) that is not part of a primary key. C1‚ C3 ( C2‚ C4‚ C5 represents a set of proper functional

Normalization A logical design method which minimizes data redundancy and reduces design flaws. Consists of applying various “normal” forms to the database design. The normal forms break down large tables into smaller subsets. First Normal Form (1NF) Each attribute must be atomic • No repeating columns within a row. • No multi-valued columns. 1NF simplifies attributes • Queries become easier.

In Montessori education‚ the term “normalization” has a specialized meaning. “Normal” does not refer to what is considered to be “typical” or “average” or even “usual”. “Normalization” does not refer to a process of being forced to conform.

Normalization refers to the focus‚ concentration and independence of the child‚ by his own choice. It means the child has acquired

August 4‚ 2009 What is Database Normalization? Database Normalization is a systematic way of ensuring that a database structure is suitable for general – purpose quering and normalization is the process of efficently organizing data in a database. This process was first introduced in 1970 by E.F. Codd and has since been redefined to higher normal forms. The two goals of the normalization process are: eliminating redundant data and ensuring that data dependencies make sense. These goals reduce

advantages and disadvantages of normalization. The process of normalization brings about organization to the database that it is applied to. Normalization makes everyone’s job easier due to the fact that it gets rid of as much useless data as possible. Repeated data is processed and simplified into single data. Repeated data‚ for example such as having someone named JOHN DOE in one table and the same person’s name JOHNNY M. DOE in another table. Modifying a table with as little data as possible
