Domain Driven Design is a complex pattern, but not tightly coupled with the backend database. In this approach, classes are structured in such a way as to represent the entity of the domain and not the table. For example, if we are going with the DDD pattern, we may have three tables--User, Address, and Profile, which represent the company's employee as a domain entity. This is a good approach, however, it takes sufficient time to understand and structure the domain entities. It represents the business language and hides the logical details from the presentation layer.
