Angular JS Create and display data dynamically

1. Stored procedure.

The accounts table is modified according to instructions stored in the action table. Each row in the action table contains an account number, an action to be taken (I, U, or D for insert, update, or delete), an amount by which to update the account, and a time tag used to sequence the transactions.

On an insert, if the account already exists, an update is done instead. On an update, if the account does not exist, it is created by an insert. On a delete, if the row does not exist, no action is taken.
