tjenestelayer

A tjenestelayer, or service layer, is an architectural pattern in software development. It acts as an intermediary between the presentation layer and the domain or business logic layer. The primary purpose of a tjenestelayer is to expose the business logic in a way that is consumable by various clients, such as a web interface, a mobile application, or other services.

This layer typically encapsulates the core operations that the application can perform. Instead of clients directly interacting with data access objects or complex domain entities, they make requests to services defined within the tjenestelayer. These services then orchestrate the necessary actions, which might involve retrieving data, performing calculations, and updating the application's state.

By separating concerns, the tjenestelayer promotes modularity and maintainability. It allows for changes in the presentation layer without impacting the business logic, and vice versa. It also facilitates code reuse, as the same business logic can be accessed through different client applications via the standardized service interfaces. This pattern helps in creating a cleaner and more organized codebase, making it easier to manage complexity and evolve the application over time.
