Can you explain what is root data? Can you give an example? – Ismael Dec 16 '17 at 13:55

Root data means data inserted while creating the contract. – Veera Dec 17 '17 at 6:52

Perhaps this is relevant ethereum.stackexchange.com/a/1061. From a contract you cannot access the previous state of a variable, you have to explicitely track the variable changes in a mapping for example. – Ismael Dec 18 '17 at 4:02

Check the solidity documentation about events, if you have more doubts try asking a new question. – Ismael Dec 18 '17 at 16:53
