Customer_No Service Code A22 S01 B10 S03 C04 S05 C13 S02 C23 S03 D21 S04 G34 S04 K10 S01 M32 S01 N00 S02 P12 S05 S11 S05 T16 S06 W45 S02 Step 2 Insert a picture in the supervisor table for Janet Febo, Kyle Martinson, and Elena Rogers. See below for what an acceptable picture is NOT.
NOTE: Here is an example of a picture that is not acceptable for a picture of a supervisor. Please make every attempt to size the picture so that all the features can be seen. NOTE: Here is an example of a picture that is acceptable for a picture of a supervisor. Please make every attempt to size the picture so that all the features can be seen. Step 3 Establish one-to-many relationship between the tables in the database.
Use the tables given to you in the database. Do not create any new tables to establish the relationship(s). Enforce referential integrity for the relationship(s). Step 4 Create a query that shows the ID Number, Amount Paid, and Balance Due. Return the top 5 records of the customers with the highest balance.
All fields in the query are to show when the query is run. Call the query BALANCE_DUE. Step 5 Create a new query. Each customer has paid an amount toward the total bill due with a balance remaining. The query is to show The Customer Name, Address, City, State, Zip Code, Balance, Amount Paid and what is still owed.
The amount spent is based on the balance due minus the amount paid. All fields in the query are to show. Call the query CUSTOMER_OWES. Step 6 Create a query using all fields from the Customers Request table. Determine how many hours are remaining for each Customer Number.
The remaining hours is determined by total hours minus hours spent. Use all fields in the query. Call the query HOURS_REMAINING. Step 7: Create a parameter query that will ask you for the supervisor’s number of the customer. Include the Customer number, Customer name, address, city, and state.
The name of the query is CUSTOMER_SUPERVISOR. Using the ORDERS database, complete Step 8 through Step 9. Step 8: Apply the concepts of total queries, create a query which shows the total profit for all orders placed. The answer should be in currency format. The name of the query is called TOTAL_SALES.
Step 9: Apply the concepts of a crosstab query to create the following crosstab query. I would like to see each state and the subcategory quantities for each state and the total profit. The name of the query is called SUBCATEGORY_CROSSTAB. Using the ADVENTUREWORKS database, complete Step 10. Step 10: Create an update query.
In the product table, we want to increase the safety stock level by 20%. Use an update query to accomplish this. In the query include the Name, Safetystock Level, and Reorder Point field. The name of the query is called UPDATE_SAFETY STOCK. Be sure that all fields show when the query is complete.
Step 11: Upload your work. Be sure that the professor can open what you have uploaded. Be sure you upload all databases as required. Please upload them at the same time. If you make any corrections and need to upload again, please upload all databases. Remember: I only look at your most recent upload.

Comprehensive Solution for Chapter 9 Assignment: Landscape Database
This assignment focuses on various aspects of database management using the Landscape database, including inserting look-up fields, adding images to tables, establishing relationships, creating queries, and performing updates. Each step in this solution reflects best practices in database management and queries.
Step 1: Inserting the Data as a Look-Up Field in the Customer Table
In Microsoft Access, you can easily create a lookup field. To insert the service codes into the Customer table:
1. Open the Customer table in Design View.
2. Select the field where you want to add the Service Code as a lookup (e.g., Service_Code).
3. Change the Data Type to Lookup Wizard.
4. When prompted, choose to "I want the lookup field to get the values from another table or query" and select the appropriate table that holds your service codes.
5. After completing the setup, enter the following data based on the instructions provided:
| Customer_No | Service Code |
|-------------|--------------|
| A22 | S01 |
| B10 | S03 |
| C04 | S05 |
| C13 | S02 |
| C23 | S03 |
| D21 | S04 |
| G34 | S04 |
| K10 | S01 |
| M32 | S01 |
| N00 | S02 |
| P12 | S05 |
| S11 | S05 |
| T16 | S06 |
| W45 | S02 |
Step 2: Insert Pictures in the Supervisor Table
To insert images into the Supervisor table for Janet Febo, Kyle Martinson, and Elena Rogers:
1. Open the Supervisor table in Design View.
2. Add a new field for images, preferably with the data type set to Attachment.
3. For each supervisor, you will need to locate high-resolution images that clearly depict their features, resizing accordingly.
4. Insert the images by selecting the Attachments field and clicking on the paperclip icon to add the supervisor's image.
It’s important to ensure that the images are appropriately sized and clear for identification. This may refer to standards of professionalism and clarity (Santos et al., 2022).
Step 3: Establish One-to-Many Relationship Between Tables
To establish relationships:
1. Open the Relationships window in Access.
2. Drag the Customer table into the window along with other tables (like the Orders or Service table).
3. Identify the primary key in the Customer table and drag it to the matching foreign key in the second table.
4. In the Edit Relationships dialog, check "Enforce Referential Integrity" to maintain data consistency.
This ensures that each customer can be tied to multiple service instances without redundant entries.
Step 4: Create the BALANCE_DUE Query
To create a BALANCE_DUE query:
1. Go to the Create tab and select Query Design.
2. Add the relevant tables and fields: ID Number, Amount Paid, and Balance Due.
3. In the criteria section for Balance Due, sort the entries from high to low.
4. Set up the property to display only the top 5 records.
The SQL syntax for this query might look like this:
```SQL
SELECT TOP 5 ID_Number, Amount_Paid, Balance_Due
FROM Customers
ORDER BY Balance_Due DESC;
```
Step 5: Create the CUSTOMER_OWES Query
For this query:
1. Again, use the Query Design feature.
2. Select the Customer Name, Address, City, State, Zip Code, Balance, Amount Paid, and calculate what is still owed.
3. Create a calculated field like this:
```SQL
Amount_Owed: [Balance] - [Amount_Paid]
```
The resulting SQL query might look like this:
```SQL
SELECT Customer_Name, Address, City, State, Zip_Code, Balance, Amount_Paid, (Balance - Amount_Paid) AS Amount_Owed
FROM Customers;
```
Step 6: Create the HOURS_REMAINING Query
1. Open a new query.
2. Include all fields from the Customers Request table and calculate remaining hours by subtracting hours spent from the total hours.
The SQL could look like:
```SQL
SELECT *, [Total_Hours] - [Hours_Spent] AS Remaining_Hours
FROM Customers_Request;
```
Step 7: Create the CUSTOMER_SUPERVISOR Parameter Query
1. Go to Query Design and select the relevant fields.
2. In the criteria for Supervisor Number, use this prompt:
```SQL
[Please Enter Supervisor Number:]
```
Your SQL statement will look like this:
```SQL
SELECT Customer_No, Customer_Name, Address, City, State
FROM Customers
WHERE Supervisor_Number=[Please Enter Supervisor Number:];
```
Step 8: Create the TOTAL_SALES Query
In the Orders database:
1. Use the Total button in the Query Design to sum profits.
2. Select fields that account for total sales.
The SQL may look like this:
```SQL
SELECT SUM(Profit) AS Total_Sales
FROM Orders;
```
Step 9: Create the SUBCATEGORY_CROSSTAB Query
To create a crosstab query:
1. Choose Crosstab Query Wizard under Create.
2. Choose fields for rows (states) and columns (subcategories) along with the sum of profits.
3. Specify totals in the appropriate section.
The SQL may be structured as:
```SQL
TRANSFORM SUM(Profit) AS Total_Profit
SELECT State
FROM Orders
GROUP BY State
CROSSTAB SUBCATEGORY;
```
Step 10: Create an Update Query for the ADVENTUREWORKS Database
To adjust the safety stock level in the product table:
1. Create an update query:
2. Set the criteria for safety stock and execute.
The SQL might look like this:
```SQL
UPDATE Products
SET SafetyStockLevel = SafetyStockLevel * 1.2;
```
