title: Can I create Corda Custom Data Tables?
body: <p>Reference code :-<br>
  GIT clone url  :- <code>git clone https://github.com/corda/cordapp-tutorial</code><br>
  Release M14    :- <code>git checkout -b release-M14.0</code></p>
  
  <p>I am little bit confused about how the data flows in Corda. I have some database releated queries:</p>
  
  <ol>
  <li><p>Whether the database structure is fixed or we can add our custom tables in it?</p></li>
  <li><p>Where can I see the data flowing in tables, when I do a cash transaction which I can see in VAULT_CASH_BALANCES 
  table in my H2 database client but apart from cash I am unable to see any details of my other transactiosn i.e. if I 
  save a string then I am unable to get the information, I only get the transaction Id for that.
  Is it possible to get entire data flow diagram?</p></li>
  <li><p>Do the Node and Vault tables created every time when I build a code?</p></li>
  </ol>
