📚Layers
Entities Layer
The entities layer is a layer where we store our database data. We have three folders Abstract, Concrete and DTOs in the Entities layer.
The abstract folder is used to store abstract objects (e.g Interfaces) while the concrete folder is used to store concrete objects (e.g Classes).The DTOs folder is used to store Data Transmission Objects (CarDetailDto)
This layer coordinates the application, processes commands, makes logical decisions and evaluations, and performs calculations. It also moves and processes data between the two surrounding layers -DataAccess and Presentation. We have 5 folders Abstract, Concrete, Constants, Dependency Resolvers and ValidationRules in the Business Layer.
