maintaining parent-child relationship during deletion

Maintaining parent-child relationship during deletion refers to the practice of preserving the association between a parent entity and its child entities when deleting or removing any records from a database or hierarchical data structure. By ensuring the integrity of this relationship, it guarantees that the parent's structure and consistency are maintained, even in the absence of certain child data. This can be achieved through various techniques such as cascading deletes, where the deletion of a parent will automatically trigger the deletion of its associated child entities, or by employing referential integrity constraints to prevent deleting parents that still have child records.
