Can I create Corda Custom Data Tables?

mariaevinne

I am little bit confused about how the data flows in Corda . I have some database releated queries :-

1.) Whether the database structure is fixed or we can add our custom tables in it ?

2.) 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 .

3.) Do the Node and Vault tables created every time when I build a code ?
