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.
