Develop the Mock Service

Explore how to build a mock service managing many-to-many bi-directional relationships between Clients and Accounts. Understand how to implement create, find, remove, and presence check operations using an enum-based singleton in-memory database. This lesson prepares you to manage linked object data efficiently for server-side Java applications.

We'll cover the following...

- add function
- Create operation
- Row identifier operation
- Remove operation
- The isPresent operation
