A primary key uniquely identifies are record in a Table and cannot be null A foreign key helps connect databaae and references a primary key. To bring this table to first normal form, we split the table into two tables and now we have the resulting tables: Now first normal form is satisfied, as the columns on each table all hold just one value. Return to Database Normalization Other Normal Forms: Second Normal Form Third Normal Form

Normalization: Normalization is a process in which simple and more reliable database structure is implemented. It is used to create a suitable set of relations for storing the data. This process works through different stages known as normal forms. These stages are 1NF, 2NF, 3NF, etc. Each normal form has certain requirements or condition. Normalization: 1NF, 2NF, 3NF, BCNF, 4NF, 5NF • Normal Forms Based on Primary Keys • General Definitions of Second and Third Normal Forms • Boyce-Codd Normal Form • Multivalued Dependency and Fourth Normal Form • Join Dependencies and Fifth Normal Form 8 Logical Database Design We are given a set of tables specifying the database
