Develop the Data Access Tier

Explore how to build the data access tier for many-to-many bi-directional relationships between Client and Account entities. Learn to implement key operations like fetching all records and checking record existence using Hibernate's query methods, supporting test-driven development.

We'll cover the following...

- Find all records operation
- The isPresent operation
