v19 v20 76 76 === 1NF Check 77 77 Every column in the database holds just one value, so there are no lists or multi-value attributes in the cells. There are no repeating columns, each table has a primary key, and all attributes are atomic, so my relations satisfy 1NF. 78 The candidate key of R is: CK = {chapter_id, genre_id, list_id, notification_id, suggestion_id, comment_id, status, content_type, suggestion_type, roles, permission_level} 79 since it is the only combination whose closure contains all attributes of R, and no proper subset of it can determine all attributes of R. 78 80 79 81 === 2NF Check
