An account is the representation of a bank account inside a financial institution. A user can have one or more accounts in an institution.
For example, one user (or link) can have a checking account, several credit cards, and a loan account.
Querying for a user's account information is useful as you can get information regarding:
- what types of accounts the user has
- the balance for each account (savings, checking, credit card, loan, and so on)
