| - | ====== Exercise Groups ====== | ||
| - | |||
| - | This page describes a minor part of the [[:stats:start]] [[:stats:schema]], namely the exercise groups. It is a part of [[exercise]]. | ||
| - | |||
| - | ===== Schema ===== | ||
| - | |||
| - | <code xcend> | ||
| - | element groups { | ||
| - | element group * id { [ count(./id, ..exercise/students/student/group) < ./maxSize ] # 4.1, 2.8 | ||
| - | attribute day { "Monday" | "Tuesday" | "Wednesday" | "Thursday" | "Friday" | "Saturday" | "Sunday" } | ||
| - | attribute time { string } | ||
| - | attribute location { string } | ||
| - | attribute curSize { integer [ . = count(../id, ..exercise/students/student/group) ]} # NEW | ||
| - | attribute maxSize { integer [ . >= 0 ]} # 3.1 | ||
| - | |||
| - | element tutor * account {[ exists //accounts/account[./account] ]} # 1.5, 2.9 | ||
| - | } | ||
| - | } | ||
| - | </code> | ||
| - | |||
| - | ===== Procedures ===== | ||
| - | |||
| - | ==== Change Attributes ==== | ||
| - | |||
| - | {{page>stats:proc:changeAttributes (Group)&noheader&nofooter}} | ||
| - | |||
| - | ==== Tutor Management ==== | ||
| - | |||
| - | The procedures for tutor management can be directly taken from the [[account]] section. In an OO setting this placement of the method in the ''Group'' class takes the least number of explicit parameters, as the exercise and group ids are implicit. | ||
| - | |||
| - | {{page>stats:proc:grantTutorRights&noheader&nofooter}} | ||
| - | |||
| - | {{page>stats:proc:revokeTutorRights&noheader&nofooter}} | ||
| - | |||
| - | ==== Member Management ==== | ||
| - | |||
| - | Another example of another association of procedures; The sign up and out procedures for students from the [[exercise]] section could also be offered on groups, as they have the necessary parameters (It is not currently realized like this in the implementation). | ||
| - | |||
| - | {{page>stats:proc:signUpGroup&noheader&nofooter}} | ||
| - | |||
| - | {{page>stats:proc:signOutGroup&noheader&nofooter}} | ||
