Develop the Mock Service

Explore how to develop a mock service in Java utilizing an in-memory data store to manage create, find, edit, and remove operations for a one-to-many bi-directional relationship. This lesson guides you through implementing a singleton pattern, handling data operations with ItemDto, and preparing for user interface integration.

We'll cover the following...

- add function
- Create operation
- Row identifier operation
- Remove operation
- Edit operation
