If we have Weight and Marks in Assessment entity and the Weight has the description of this it must be Non-zero percentage. And also the Marks attribute stores the maximum possible raw mark for assessment (e.g., 30), while Weight stores of the weight of this assessment for the paper as a whole (e.g., 10%). If Marks is not specified, then Weight is used for both. How we can convert this into schema in SQL????
