What I didn't learn is that a similar mechanism exists at a higher level: software architecture patterns. These are templates for the overall layout of an app or application. All of them have their advantages and disadvantages. And they all deal with specific issues. The layered pattern of layered template is probably one of the most well-known patterns of software architecture. Many developers use it without knowing its name. The idea is to divide the code into layers where each layer has a certain responsibility and provides a service to a higher level. There is no predetermined number of layers , but these are the ones you see most often: The presentation or user interface layer of the Application Layer Business or Domain Layer Perseverance or the level of access to the data layer of the database layer Idea is that the user initiates a portion of the code in the presentation layer by performing certain actions (such as pressing a button) . The view layer then triggers a base layer , i.e. the application layer. Then we go into the business layer and finally the level of perseverance keeps everything in the database. Thus , the higher layers depend on and make calls to the lower layers. You'll see variations of this , depending on the complexity of the apps. Some apps may omit the application layer , while others add a caching level. You can even combine two layers into one. For example , the ActiveRecord pattern combines layers of business and perseverance. As mentioned , each layer has its own responsibility. The presentation layer contains the graphic design of the app , as well as any code to process user interaction. You should not add logic that is not user-specific in this layer. The business layer is where you put the model and logic that is specific to the business problem you are trying to solve. The application layer is between the presentation layer and the business layer. On the one hand , it provides abstraction , so the level of view should not know the business layer. Theoretically , you can change the presentational stack without changing anything else in the app (for example , reworking winForms on WPF) . On the other hand , the application layer provides a place to introduce a certain coordination logic that doesn't fit into the business or presentation layer. Finally , the save layer contains a code to access the database layer. The database layer is the main technology of the database (e.g. S' L Server , MongoDB) . The Save Layer is a set of code to manage the database: statements on the SDL , About Connectivity , etc. Benefits developers are familiar with this model. It's an easy way to write a well-organized and testable application. Disadvantages This usually leads to monolithic applications that are difficult to separate afterwards. Developers often write a lot of code to get through different layers without adding any value to these layers. If all you do is write a simple CRUD app , a layered template may be redundant for you. Perfect for standard business applications that do more than just CRUD microkernel template operations , or a plug-in template , is useful when your app has a core set of responsibilities and a collection of interchangeable pieces on the side. The microkernel will provide the entry point and the overall flow of the application without knowing what the various plug-ins are doing. An example would be a task planner. Microkernel can contain all the logic of scheduling and running tasks , while plugins contain specific tasks. As long as plug-ins stick to a predetermined API , the microkernel can cause them to know the details of the implementation without having to know the details of the implementation.
