Transactions

Transactions can be of type:

• Income/Credit
• Expense/Debit
• Transfer (between own accounts)

In logical terms, a transfer from A -> B is treated by the API as two different transactions:

1. X amount is debited from A
2. X amount is credited in B

However, for accessibility and data integrity, they're still stored as a single entry.

Here's a typical DB representation of 3 different transactions: 1 debit, 1 credit and 1 transfer (simplified and truncated):

transaction_id	type	accounts_account_from_id	accounts_account_to_id	description
1	E	101	NULL	debit from #101
2	I	NULL	101	credit to #101
3	T	101	102	transfer from #101 to #102
