Design Notes for Session & Subject Domains

sessionDomains.txt

A Department can be though of as the highest authority in a school when it comes to developing, maintaining and implementing curriculums for a specific academic field. Ther can be departments of math, science, literature, business, etc. Each department must have a teacher in charge that is the overall responsible.

class Department {
String name
String code
String description
Teacher headOfDepartment
}

A subject is a specific subject matter that is offered by a school.
class Subject {
String name
String code
Department department
}

A building is a physical building in a school.
class Building {
String name
String code
String description
}

A classroom is a specific physical location in a school where classes are imparted:
class Classroom{
String name
String code
String description
Building building
}


Days of the week:
class Day{
String name
String code
}

A TimePeriod is the days of the week and the times when a class is imparted.
class TimePeriod{
String timeOfDay
static hasMany = [days: Day]
}

A SessionStatus identifies the status a session is currently in. These can be:
1.Active
2.Closed
3.Discontinued
4.Full
class SessionStatus{
String name
String code
}

A Session identifies the time & place when a subject is imparted.
class Session{
String name 
String code //Not so sure about code & name
Subject subject
TimePeriod timePeriod
Classroom classroom
Teache teacher
SessionStatus status
int maximumNumberOfStudents
Date startDate
Date endDate
//Dont know if the following 2 are necessary.
Date dateDiscontinued
Date dateClosed
}

A group of session is used mainly for high schools. These identify the 'homerooms'.
class SessionGroup{
Teacher homeroomTeacher
static hasMany = [sessions: Session]
}


A school year identifies the start date and end date of a school year. Since the date already includes a year field, I do not find it necessary to include a separate field for year (e.g. 2011-2012).
class SchoolYear{
Date startDate
Date endDate

//The string respresentation of the school year in yyyy - yyyy format
String toString(){
  "${1900 + startDate} - ${1900 + endDate}"
}
}


The school years are all divided into academic terms:
class AcademicTerm{
SchoolYear schoolYear
int term //1, 2, 3, etc.
Enum termType // An enum with values: Semester, Trimester, etc.
}

Absentisms captures the students who were absent on a specific day for a session.
class Absentee{
Student student
Session session
Date dateAbsent
}

It is also important to record when a student arrives late for a session:
class LateIncidents{
Student student
Session session
Date dateLate
String timeArrivedForClass
}


Assessments are categorized to make it easier to assign weights to each type of assessment:
class AssessmentCategory{
String name
String code
}


Assessments hold different weights based on what category of assessment they are. These can be configured per session :
class SessionAssessmentWeight{
Session session
AssessmentCategory assessmentCategory
int weight
}

class AssessmentWeightTemplate{
Teacher teacher
AssessmentCategory assessmentCategory
int weight
}

class AssessmentWeightGroupTemplate{
Teacher teacher
static hasMany = [assessmentWeightTemplates : AssessmentWeightTemplate]
}



Assessments contain information about a student's grade for assessments on a session:
class Assessment{
AssessmentCategory assessmentCategory
Session session
Date assessmentDate
Grade grade
}
