Define BCNF. Now that ORDER_ITEM is in 3NF, is it also in BCNF? If not, why not, and what would have to be done to put it into BCNF? Make any changes necessary to put ORDER_ITEM into BCNF. If this step requires you to create an additional table, make sure that the new table and any other tables created in previous steps are also in BCNF.BCNF is any table that 1) in Third Normal Form, and 2) and all determinates are candidate keys. Because the original question was not in Second Normal Form, it was NOT in BCNF. The solution in B fixes this problem, and then both ORDER_ITEM and PRODUCT are in BCNF.

This activity uses a 3ra party app. Though your activity may be recorded, a refresh may be required to update the banner to left state Snow Record contains the amount of snow fall (in cm) for various cities. Rows represent a city and columns represent the snow fall for a given month. Assign city Snow Record with all elements of row Num. Ex: If State Snow Record is [17.3, 20.3; 4.6.6.2] and row Num is 2, then city Snow Record is [4.8, 6.2].
