I am making a game based skill where I take answers from user but the answers are not validated yet. I have to feed in answers based on real world events( it is a prediction based game, events which haven't taken place yet) and then evaluate the points and tell user his/her score when they open the skill next day. I know it will involve using DynamoDB for storing answers. But how to feed in answers for validation. Should I introduce a default value and then change my lambda function daily with the actual answers for validation?
