In what cases is cascading used in system architecture?

Cascade in system architecture is advisable to use when it is necessary to sequentially apply several operations or changes that depend on each other.

For example:

• In ORM (Object-Relational Mapping), cascading allows automatically saving or deleting related entities along with the main one.
• In business logic, when changing one object requires updating related objects.

Advantages:

• Simplifies management of related data
• Reduces the amount of code needed to handle dependencies

Disadvantages:

• Can lead to unexpected changes if cascading is misconfigured
• Increases transaction complexity and potentially puts more load on the database

Use cascading when the relationships between objects are clearly defined and atomicity of operations on them is required.
