Help in Creating Relationships in a table

[forest8]

Hi

This is a follow to a previous question concerning relationships in a table.

These are my tables I have in my database.

Students
StudentsID
LastName
FirstName
HomeroomTeacher
(ohter info relating to the student)

Cases
CaseNo_ID <PK>
StudentID <FK>

Categories
CategoryID <PK>
Category (e.g. School, Community, Individual, Peers, Family)

Issues
IssuesID <PK>
Issues (text, e.g. lack of role models)
CategoryID <FK>

StudentIssues
CaseNoID <link to Cases Table>
IssuesID <Link to issues Table>

Actions
ActionsID <PK>
Actions (text, eg. New Adult Role Models)
CategoryID <FK>

StudentActions
CaseNoID <link to Cases Table>
ActionsID <link to Actions Table>

Does this look right to anyone?

Is it possible to merge the Actions and Issues tables together or is it best
to leave them separate?

Thank you in advance for your help

Is it possible to merge the Actions and Issues tables together or is it best

to leave them separate?

Not if an issue can have more than one action.
Also you have issues and actions both linked to category, what is the
purpose of category? Might you not have different subsets of categories for
issues and actions?

Hi there

All the issues and actions are tied to a category.

An Issue can have more than 1 action. For instance, if a student has no role
model in his family, then a possible action is to develop a positive role
model, [Category: Family, Issue: Lack of Role Model; Action: Develop Adult
role models]

Several issues may have the same action. For instance, a youth has no adult
role models and has a poor relationship with his family, then the action is
to develop a positive role model. [Category: Family, Family. Issue: Lack of
Role Model, Action: Develop adult role model]

Does this make sense?

Thanks

While I'm sure that most (?all) students have a "homeroom teacher" at some
point in time, it is true that they have the SAME homeroom teacher for all
time? Barring court or marital action, most individuals have/keep the same
first and last name throughout their lives.

I suspect your [HomeroomTeacher] field (and possible some of your {other
info relating to the student} actually belongs in a different table).

No!

You need a teachers table:
TblTeacher
TeacherID
<other teacher fields>

You need a classroom table:
TblClassroom
ClassroomID
Classroom

You need a homeroom teacher table. You will need to record this every school
year.
TblHomeroomTeacher
HomeroomTeacherID
ClassroomID
TeacherID
SchoolYear

You can now record a student's homeroom teacher which identifies the school
year and identifies the student's homeroom. You will need to record this
every school year.

TblStudent
StudentsID
LastName
FirstName
(ohter info relating to the student)

TblStudentHomeroom
StudentHomeroomID
StudentID
HomeroomTeacherID

Regarding issues and actions ........
First, your category table looks good:
TblCategory
CategoryID <PK>
Category (e.g. School, Community, Individual, Peers, Family)

Your Issue table looks good:
TblIssue
IssueID <PK>
CategoryID <FK>
Issue (text, e.g. lack of role models)

Your action table looks good:
TblAction
ActionsID <PK>
CategoryID <FK>
Action (text, eg. New Adult Role Models)

Now you need a table that identifies the appropriate actions for each issue:
TblIssueAction
IssueActionID
IssueID
ActionID

Now for Cases. I am going to assume you want to create a case history for a
student each school year. This means at the first time there is an issue
with a student in a school year, he is assigned a case number and keeps that
same case number throughout the school year. In the next school year, if
there is an issue with a student, he is assigned a new case number.

TblCase
CaseID
StudentHomeroomID (identifies the student, his home room and the school
year)
CaseNumber

Now you need a table to record each time there is an issue in a case:
TblCaseIssue
CaseIssueID
CaseID
IssueID
IssueDate

Finally you need a table to record what actions were taken for each issue:
TblCaseIssueAction
CaseIssueActionID
CaseIssueID
ActionID
ActionDate

.... that should have been "IS IT true ..."
