Revisiting the appeals table
The SBA database now contains a table for storing loan applicant appeal requests. The table contains only a PRIMARY KEY and a text column for the appeal. It is useful to track additional information such as when the appeal was received, whether or not the decision was reversed after the appeal, and the date when the appeal was reconsidered. You will define a new version of the appeals table to capture this information.
