/**
* Serialized Entity Pattern.
*
* <p> Serialized Entity Pattern allow us to easily persist Java objects to the database. It uses Serializable interface
* and DAO pattern. Serialized Entity Pattern will first use Serializable to convert a Java object into a set of bytes,
* then it will using DAO pattern to store this set of bytes as BLOB to database.</p>
*
* <p> In this example, we first initialize two Java objects (Country) "China" and "UnitedArabEmirates", then we
* initialize "serializedChina" with "China" object and "serializedUnitedArabEmirates" with "UnitedArabEmirates",
* then we use method "serializedChina.insertCountry()" and "serializedUnitedArabEmirates.insertCountry()" to serialize
* "China" and "UnitedArabEmirates" and persist them to database.
* Last, with "serializedChina.selectCountry()" and "serializedUnitedArabEmirates.selectCountry()" we could read "China"
* and "UnitedArabEmirates" from database as sets of bytes, then deserialize them back to Java object (Country). </p>
