1 -------------------------------------------------------------------------------- 2 DB table structure 3 -------------------------------------------------------------------------------- 4 5 The DB API models an underlying table structure that may or may not literally exist, depending on what transformations the schema modules make. However, this is the table structure that is presented to users of the DB module. 6 7 The order of key fields in this list is the order that arguments should be passed to the exists(), get(), and delete() schema functions, and the order of the values in the return value of the list() schema function. 8 9 * indicates a key 10 => indicates a relation 11 ! indicates an override field 12 ~ indicates a "dynamic" field 13 14 password 15 user_id *,=> user.id 16 password 17 permission 18 user_id *,=> user.id 19 permission 20 key 21 user_id *,=> user.id 22 key 23 user 24 id * 25 first_name 26 last_name 27 email_address 28 student_id 29 status 30 section 31 recitation 32 comment 33 set 34 id * 35 set_header 36 problem_header 37 open_date 38 due_date 39 answer_date 40 problem_order 41 set_user 42 user_id *,=> user.id 43 set_id *,=> set.id 44 psvn 45 set_header ! 46 problem_header ! 47 open_date ! 48 due_date ! 49 answer_date ! 50 problem_order ! 51 problem 52 id * 53 set_id *,=> set.id 54 source_file 55 value 56 max_attempts 57 problem_user 58 user_id *,=> user.id 59 set_id *,=> set.id 60 problem_id *,=> problem.id 61 source_file ! 62 value ! 63 max_attempts ! 64 problem_seed 65 status ~ 66 attempted ~ 67 last_answer ~ 68 num_correct ~ 69 num_incorrect ~
