/**
* This class intends to act as the primary entity that hides all DAO instantiation related complexities and logic so
* that the business objection handling layer doesn't need to be aware of the same providing seamless plug-ability of
* different data sources, connection acquisition mechanisms as well as different forms of DAO implementations to the
* high-level implementations that require device management related metadata persistence.
* <p/>
* In addition, this also provides means to handle transactions across multiple device management related DAO objects.
* Any high-level business logic that requires transaction handling to be done via utility methods provided in
* DeviceManagementDAOFactory should adhere the following guidelines to avoid any unexpected behaviour that can cause
* as a result of improper use of the aforementioned utility method.
* <p/>
* Any transaction that commits data into the underlying data persistence mechanism MUST follow the sequence of
* operations mentioned below.
* <p/>
* <pre>
* {@code
* try {
* DeviceManagementDAOFactory.beginTransaction();
* .....
* DeviceManagementDAOFactory.commitTransaction();
* return success;
* } catch (Exception e) {
* DeviceManagementDAOFactory.rollbackTransaction();
* throw new DeviceManagementException("Error occurred while ...", e);
* } finally {
* DeviceManagementDAOFactory.closeConnection();
