1. The document discusses database design and normalization. It provides examples of product, order, and store tables. 2. The tables are normalized to first normal form by extracting repeating groups into separate tables and ensuring each cell contains a single value. 3. Primary keys are assigned to uniquely identify each record in tables. Foreign keys are also included to link related data across tables.
