Work Step by Step
To design a relational database for parts, suppliers, and customers, we can create three tables: Parts, Suppliers, and Customers. Additionally, we'll need a fourth table to represent the relationships between them, often called a junction or association table. Here's a basic structure:
1. **Parts Table**:
- Part_ID (Primary Key)
- Part_Name
- Other relevant attributes about parts
2. **Suppliers Table**:
- Supplier_ID (Primary Key)
- Supplier_Name
- Other relevant attributes about suppliers
3. **Customers Table**:
- Customer_ID (Primary Key)
- Customer_Name
- Other relevant attributes about customers
4. **Orders Table (Junction Table)**:
- Order_ID (Primary Key)
- Part_ID (Foreign Key referencing Parts table)
- Supplier_ID (Foreign Key referencing Suppliers table)
- Customer_ID (Foreign Key referencing Customers table)
- Order_Quantity
- Order_Date
- Other relevant attributes about orders
This design allows for many-to-many relationships between parts, suppliers, and customers. Each order in the Orders table links a part to a supplier and a customer, along with relevant details such as quantity and date. This structure avoids redundancies and ensures data integrity.
