However, storing and analyzing the data in MS Excel has numerous limitations. SPE would like to use MS ACCESS to record within the revenue cycle. As the company’s Accounting Manager, you are asked to design and

Part II: Build the
database
using ACCESS
Create a database file using your session weekday and student IDs as filename. guidelines in coming up with the data of the tables.
Required number of
Create at least 5 customers
Create at least 7 inventory items
Create at least 8 sales orders, with 5 in Jan. and 3 in Feb. 2024 Create at least 10 sales, with 6 in Jan. and 4 in Feb. 2024
(30 marks)
Use the following
entries
(records)
Create at least two employees: one salesman, one cashier. Use your full name(s) as employee name(s). If two students work together, then one student acts as salesman and the other student acts as cashier.
Create at least 8 money receipts, with 2 in Jan. and 6 in Feb. 2024. There should be at least one sales invoice that has not been settled in your database.
Create at least 1 bank account
Point to note when you create your data:
The data created should be consistent with the type of relationship. That is, if the relationship is many-to-many (one-to-many), you must come up with table(s) and data that illustrate the many-to-many (one-to-many) relationship.
Hints:
If a sales invoice includes many inventory items and you want to show the quantity sold for each item, it is not feasible to include the “Quantity Sold” field in the sales table because each sale is represented by only one row in the sales table. If you include inventory # as one of the fields in the sales table, you can only sell one inventory # in each sales invoice given there is only one cell for input.
Leave the Receipt # as blank in the Sales table if customer has not made any payment to settle an invoice. You can retrieve these sales by using the criteria: is null, within the receipt # field.

1. Generate
i the January 2024 sales report; in your query output, you should display the following information: sales invoice date, sales invoice number, sales invoice amount, customer #, employee # and receipt #. (10 marks)
ii the total January revenue using the query in (i). (5 marks)
iii the January 2024 gross margin by inventory item; in your query output you should display the following information: inventory item#, inventory item description, sum of quantity sold, unit price, unit cost, total revenue, total cost of goods sold and gross margin amount
and gross margin percentage. (10 marks)
(Hints for iii: If you use two queries, the first query takes out those sales in January. The second query utilizes the first query to calculate total revenue, total cost of goods sold and gross margin. In the second query, do not include any date field.)
2. Which inventory item is most popular in terms of total sales quantity for the two months combined? Rank the quantity sold in descending order. Your output should display inventory item#, inventory item description and sum of quantity sold. (No date field is necessary as you are including all sales data in both January and February) (7 marks)
3. Assume a sales commission rate of 5%, generate a report that shows the commission income by salesman for January. The commission income is based on the total sales made by a salesman multiplied by the commission rate. Your report should show employee #, employee name and commission. (Hint: use one of the tables and query 1(i)). (8 marks)
4. Which customers have not settled their sales invoices? Generate a report that shows the following fields: sales invoice #, sales invoice date, customer #, customer name, employee #, employee name, and receipt #. (10 marks)
