I’m trying to define a table to store student grades for a online report

  • 0

I’m trying to define a table to store student grades for a online report card. I can’t decide how to do it, though.

The grades are given by subject, in a trimestral period. Every trimester has a average grade, the total missed classes and a ‘recovering grade’ (I don’t know the right term in English, but it’s an extra test you take to try to raise your grade if you’re below the average), I also gotta store the year average and final ‘recovering grade’. Basically, it’s like this:

      |1st Trimester      |2nd Trimester      |3rd Trimester Subj. |Avg.  |Mis.  |Rec  |Avg.  |Mis.  |Rec  |Avg.  |Mis.  |Rec  |Year Avg.  |Final Rec. Math  |5.33  |1     |4    |8.0   |0           |7.0   |2           |6.5        |7.0 Sci.  |5.33  |1     |4    |8.0   |0           |7.0   |2           |6.5        |7.0

I could store this information in a single DB row, with each row like this:

1tAverage | 1tMissedClasses | 1tRecoveringGrade | 2tAverage | 2tMissedClasses | 2tRecoveringGrade

And so on, but I figured this would be a pain to mantain, if the scholl ever decides to grade by bimester or some other period (like it used to be up until 3 years ago).
I could also generalize the table fields, and use a tinyint for flagging for which trimester those grades are, or if they’re the year finals. But this one would ask for a lot of subqueries to write the report card, also a pain to mantain.

Which of the two is better, or is there some other way? Thanks

  1. You could try structuring it like this with your tables. I didn’t have all the information so I made some guesses at what you might need or do with it all.

    TimePeriods:

    • ID(INT)
    • PeriodTimeStart(DateTime)
    • PeriodTimeEnd(DateTime)
    • Name(VARCHAR(50)

    Students:

    • ID(INT)
    • FirstName(VARCHAR(60))
    • LastName(VARCHAR(60))
    • Birthday(DateTime)
    • [any other relevant student field information added…like contact info, etc]

    Grading:

    • ID(INT)
    • StudentID(INT)
    • GradeValue(float)
    • TimePeriodID(INT)
    • IsRecoveringGrade(boolean)

    MissedClasses:

    • ID(INT)
    • StudentID(INT)
    • ClassID(INT)
    • TimePeriodID(INT)
    • DateMissed(DateTime)

    Classes:

    • ID(INT)
    • ClassName (VARCHAR(50))
    • ClassDescription (TEXT)
    • 0
