Table Inheritance pattern

[iluwatar]

Description

The Table Inheritance design pattern involves modeling a class hierarchy in a relational database. Each class in the hierarchy is mapped to its own table. The main elements of this pattern include:

• Class Hierarchy Representation: Each class in the hierarchy has its own table.
• Primary Key: All tables share a common primary key.
• Relationships: Tables are related through foreign keys representing the inheritance structure.

This pattern is particularly useful when different subclasses have distinct properties that need to be stored in separate tables, and it helps in organizing complex data models efficiently.

Acceptance Criteria

1. Implement the Table Inheritance pattern with a sample class hierarchy.
2. Ensure that each class in the hierarchy has its own table with a common primary key.
3. Write unit tests to verify the correct behavior of the pattern implementation, ensuring proper data retrieval across the hierarchy.
