The Case
Ms Chong started flower arrangement as a hobby in 2016, and posting her arrangements and bouquets on Instagram. Little did she know what her pictures and arrangements would be so popular. Friends and even strangers started asking her to sell them flowers.
With a large social media following and growing side business, Ms Chong has decided to go all in and run her florist business full-time with the name “Beautiful Blooms”. She will require a system to manage the buying of flowers, viewing orders and changing the status of orders.
For a start, Beautiful Blooms has decided to offer a limited selection of flowers arranged under 5 categories as shown below:
Category Sample Picture
Romantic
Birthday
Grand Opening
Condolence
Anniversary
Details of all the products can be found in Appendix A.
Currently, all orders can taken manually. Every order must include the item code, item category, add-ons (if any), customer name, delivery address, recipient name, message for recipient, special instructions (if any) and lastly delivery date and time.
As an intern in IMDA (Infocomm Media Development Authority), your supervisor has assigned you to help Beautiful Blooms automate their sales process, inventory management and order management.
Project Requirement
After several rounds of discussion, Beautiful Blooms would like to have the following essential features to be included:
Inventory management that includes setting up products, adding and removing products and pricing updates.
Sales management that allows consistent order taking, taking delivery details, update of order status etc.
Further features to be integrated in the application are the ability to filter products by category and sorting by price.
Based on you understanding, the application should display the below main menu to allow Beautiful Blooms to repeatedly perform the 2 key features.
@@@@ Beautiful Blooms @@@@
1.Inventory management
2.Sales management
0.Exit
Enter option:
Before presenting the main menu, your application needs to load the existing from “Products.txt” (Appendix A) into a collection*.
* you can decide to implement using either Dictionary or List.
Details of the 2 key features are presented below:
1.Inventory management
This feature allows the user to perform the following: (through a sub-menu)
a.View /Update blooms
b.Add new blooms
c.View / Update add-ons
d.Add new add-on
e.Back to main menu
a.This feature will list product details, as shown in Appendix A. At the end of the list, the program will display a prompt:
To update an item, enter the item code. Or enter 0 to go back to previous menu.
If there is no item with item code, display appropriate error message and return to sub-menu.
Program will display the item name, price, and status, if the item code exists.
User can enter the new price and/or new status to proceed with the update.
Any updates should also be effected into “Products.txt”
b.To setup a new item, these data elements should be collected:
Name of item
Item code: this has to be unique. Can be manually entered or automatically generated
Price.
Category: There are 5 fixed categories – Romantic, Birthday, Grand Opening, Condolence, Anniversary
The new item is created, added into the collection, with status “Available”. The “Products.txt” file is also updated with this new item.
c.This feature will list all the available add-ons, as shown in Appendix B. At the end of the list, the program will display a prompt:
To update an item, enter the item code. Or enter 0 to go back to previous menu.
If there is no item with item code, display appropriate error message and return to sub-menu.
Program will display the item name, price, and status, if the item code exists.
User can enter the new price and/or new status to proceed with the update.
