Basically, normalization is the process of efficiently organising data in a database. There are two main objectives of the normalization process:eliminate redundant data (storing the same data in more than one table)and ensure data dependencies make sense (only storing related data in a table). ...
In database systems (DBMS) which support referential integrity constraints, such as the InnoDB storage engine for MySQL, defining a column as a foreign key will allow the DBMS to enforce the relationships you define. For example, with foreign keys defined, the InnoDB storage engine will not all...
