In this tutorial https://www.ragic.com/intl/en/doc-kb/180/Calculating-a-running-balance-in-Ragic ,
the author uses an action button “Create update record button” to add the [transation id]![amount] to the [acount balance]![current balance] and keep it updated.
In this video tutorial by Berrin https://www.youtube.com/watch?time_continue=3&v=QO0ZIZNgU2Q&feature=emb_title ,
she uses the formula LAST(new balance) in the [account balance]![current balance] field to keep the running balance without the need of action buttons. This way seems more logical to me.
My question is: Will using the first method with action buttons have significant advantage in big databases?
