Managing data access in Domain-Driven Design (DDD) applications can be challenging, especially when working with different database types, like relational and NoSQL. This article explores how leveraging tools like JNoSQL and Jakarta Data helps simplify data access, making it easier to implement domain-focused repositories, integrate ubiquitous language, and naturally align business semantics with your code.
Understanding DDD vs. DAO
Before diving into the practical implementation details, it’s essential to clarify the distinction between Domain-Driven Design (DDD) and the Data Access Object (DAO) pattern. Understanding this difference will help recognize the value of domain-focused repositories in DDD applications.
