1. Declare an interface with abstract methods where each and every abstract methods represent a particular operation,
2. Prepare an implementation class for the interface and its methods
3. Get Data from Controller Layer and get DAO oBject and access Dao Methods
4. Prepare a Factory class and Factory methods to supply object to Controller Layer
