title: hyperledger fabric v0.6 modify Data in RockDB or Database
body: <p>Since the concept of blockchain is not support modification. All data that being write to Ledger will not support changing. I want to test on changing data value that store in Ledger. I try to find ways around on how to change data, but I couldn't an exact one. I know that Hyperledger Fabric v0.6, Data is stored in RockDB.</p>
  
  <p>Really Appreciate if someone could help to figure out that part. Because I also want to know that it really support un-modification. </p>
  
  <p>Also Auditor will involve in checking Data changing. I also still cannot get clear answer on What's Auditor?
  How to configure Auditor in Fabric v0.6?</p>
