| + | ==== Associated to the Stat System ==== | ||
| + | |||
| + | These are the associated procedures for [[:stats:schema:stats]], i.e. they have no necessary parameters, as the [[:stats:]] is unique and does not need disambiguation. Some of them, however, will have ''ident'' parameters, which makes it possible to offer them in these classes, too. | ||

| + | ==== Associated to Exercise ==== | ||
| + | |||
| + | These are the associated procedures for [[:stats:schema:exercise]], i.e. one of their parameters is an ''id'' of an exercise and they will most likely be offered in a corresponding ''Exercise'' class in an OO setting. Again, these procedures might be offered in other classes, too. | ||

| + | |||
| + | ==== Associated to Group ==== | ||
| + | |||
| + | These are the associated procedures for [[:stats:schema:group]], i.e. they have two parameters for the exercise id and the group id. They will also most likely be offered in a corresponding ''Group'' class in an OO setting, which has an associated ''Exercise'' object. | ||

| + | ==== Associated to Student ==== | ||
| + | |||
| + | These are the associated procedures for [[:stats:schema:student]], i.e. they have two parameters for the exercise id and the student id. They will also most likely be offered in a corresponding ''Student'' class in an OO setting, which has an associated ''Exercise'' object. | ||
