    you do not need a "data warehouse" to create data mining models.

    ok - sorry about assuming.

    I do not want to give out a straight answer because it's your project. But In simplest of terms:

    Fact table contains numbers (that you want to sum/average/count/...)

    Dimension Table contains Fields that you want to group them by.

    So if you want to group "average(marks)" by subjects.

    your fact = marks

    your dimension = subject

    I hope it's a decent starting point for you.
