Dependent Mapping pattern

[iluwatar]

Description: The Dependent Mapping design pattern is used to handle situations where the mapping of one object depends on the mapping of another object. This pattern is particularly useful in scenarios where there are complex relationships between objects and their corresponding database tables. It ensures that dependent objects are mapped correctly and consistently, maintaining the integrity of the data and the relationships between the objects.

Key elements of the Dependent Mapping design pattern include:

1. Dependent Mapper: This component is responsible for mapping the dependent objects. It coordinates with the main mapper to ensure that dependent objects are correctly mapped and persisted.
2. Main Mapper: The primary mapper that interacts with the database. It delegates the mapping of dependent objects to the dependent mapper.
3. Relationship Handling: Proper handling of relationships between the main object and its dependent objects to ensure data integrity and consistency.
4. Transaction Management: Ensuring that operations involving dependent objects are part of the same transaction to maintain atomicity.

Acceptance Criteria:

1. Implement the Dependent Mapper and Main Mapper classes that demonstrate the mapping and persistence of dependent objects.
2. Ensure that the relationship between the main object and dependent objects is correctly handled, with appropriate unit tests to verify the integrity and consistency of the data.
3. Include comprehensive documentation and examples within the codebase to illustrate the usage and benefits of the Dependent Mapping design pattern.
