It is necessary to be able to process and save an array of data in the smart contract. Perhaps Box storage can help with this?
Thank you!
Welcome to Algorand @Olga !
Since this is a quite open question, I would recommend asking it on Discord:
In general boxes allow to store “unlimited” storage but you cannot access all this storage all at once. So depending on what you want to compute over this array of data, you may need to use additional tricks.
