1.If we have a Salary coloumn in Staff entity with this description the salary must be monetary and >=$35450.00, how we can write it in into schemain SQL? 2. 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????
