Көп деңгейлі архитектурада негізгі деңгейлер немесе қабаттар қандай?

In a multi-layered application architecture, the following main levels are usually distinguished:

1. Presentation Layer — responsible for user interaction, data display, and processing user input.
2. Business Logic Layer — contains business rules and application logic.
3. Data Access Layer — responsible for interacting with the database or other data sources.

In Go, these layers can be implemented through packages or modules that separate responsibilities and simplify maintenance and testing of the code.
