The database contains a single table named PricingRules. This table is designed to store pricing information for various products, identified by their Stock Keeping Unit (SKU).
| Column | Data Type | Description |
|---|---|---|
SKU |
CHAR(1) | Primary key. A unique identifier for each product. |
UnitPrice |
DECIMAL(10, 2) | The standard unit price of the product. |
DiscountUnits |
INTEGER(3) | The quantity of items required for a discount. |
DiscountPrice |
DECIMAL(10, 2) | The total price for the discounted quantity. |
Initial data is populated into the PricingRules table as follows:
- SKU 'A': Priced at $50 each, with a special deal of 3 for $130.
- SKU 'B': Priced at $30 each, with a special deal of 2 for $45.
- SKU 'C': Priced at $20 each, with no special discount.
- SKU 'D': Priced at $15 each, with no special discount.
The database is stored in a SQLite file named checkout.sqlite inside the project directory.
