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.

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.

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
