Currently I'm working on a project which related to an entity which is Shift and the attributes are ID, Name and Description. I will require to add, edit and delete the shift record. May I know how is the validation logic performed in microflow to compare with existing record in database, and show the record is already existed if the record is existed?

You need to find out for yourself which of these attributes, or a combination of those, is unique. Since you have a shift ID, it sounds like this one is unique. Do a retrieve from database on ID = $Shift/ID. If the database retrieve works and retrieves a shift, it already exists in the database and you can show a warning. If the retrieve's result is empty, you know it didn't exist yet.
