It mediates between these two models by using a collection façade that hides the complexities of the underlying. RepositoriesĪ repository is used to manage aggregate persistence and retrieval while ensuring that there is a separation between the domain model and the data model. Repositories ensure technical complexities are kept out of the domain model. Repositories ensure that persistence ignorance is retained by storing domain aggregates behind a collection façade disguising the true underlying infrastructural mechanism. In order to avoid blurring the lines of responsibility between domain logic and infrastructure code, repositories can be employed. How do you create, persist, and retrieve domain objects while maintaining a domain model that is not distracted by technical concerns? For domain objects that need to live beyond in- memory use and be retrieved later, a mapping to a persistence store is required.
