Question 3

The best expression for an attribute representing the week that food is received so it can be matched with food already in inventory is:

Question options:

The best choice uses the DateAdd function to substract two days from the date of ReceivedTimestamp, always on Wednesdays.

The choices with “ww” would add or subtract weeks rather than days.

1. Add counts of food items served and wasted and convert the counts to dollar costs
2. Subtract costs for food items served and wasted from costs for purchases and inventory

4. Add purchases and inventory counts and convert the counts to dollar costs

Question options:

1, 4, 2, 3

Question 7

The best approach for reducing losses due to servers voiding customer bills and pocketing the cash would be to:

Question options:

change the system to make it record voided customer bills and analyze them by server

Question options:

higher or lower profits depending on the food items

accurately stated profits

overstated profits

Question 9

Suppose the following queries are available that determine costs for food items:

1. In inventory
2. Received from vendors
3. Served to customers
4. Wasted

What is the smallest number of queries required to subtract the sum of food items served and food items wasted from the sum of food items in inventory and food items received from vendors?

Question options:

1

2

3

4

Because outer joins are required, Access will only permit joining two queries at a time. Thus, one query is needed to sum food items served to customers and wasted. A second query is needed to sum food items in inventory and received from vendors. A third query is needed to combine the first and second queries.

Question 10

Your assistant has a query intended to group food items wasted by day that shows many more rows than it should. You tell your assistant to:

Question options:
