+ * high-level implementations that require device management related metadata persistence.

+ * In addition, this also provides means to handle transactions across multiple device management related DAO objects.

+ * TrackerManagementDAOFactory should adhere the following guidelines to avoid any unexpected behaviour that can cause
+ * as a result of improper use of the aforementioned utility method.
