The topic today are about <code>one-to-many</code> / <code>many-to-one</code> association relationship. It about a links of multiple tables based on a FK (Foreign Key) column which that the child table record references back to the PK (Primary Key) of the parent table row data. I also will touch <code>unidirectional</code> and <code>bidirectional</code> propagation.</p>
