-Having such an `IProductsDbContext` interface allows us to decouple our repositories (and other classes) from the concrete `ProductsDbContext` class, which provides flexibility to the final application to merge multiple `DbContext`s into a single `DbContext` to manage database migrations easier and have a database level transaction support for multi-module operations. We will see it in the *Adding a Database Migration* section.
