alkalmazáslogikától

Alkalmazáslogika refers to the set of rules, computations, and processes that define how an application functions and achieves its objectives. It is the core intelligence of a software system, dictating its behavior in response to user input, data, and external events. This logic encompasses everything from basic data validation and calculations to complex algorithms, business rules, and workflows.

The implementation of application logic is typically found within the application's code, often residing in layers responsible for processing business requirements. It is distinct from the user interface (UI) which handles presentation, and the data access layer which manages persistent storage. This separation of concerns allows for more maintainable and scalable software.

When a user interacts with an application, the application logic interprets these actions, retrieves or manipulates data as needed, and determines what the next step should be. This could involve performing calculations, making decisions based on predefined criteria, or orchestrating interactions with other parts of the system or external services.

Examples of application logic include determining eligibility for a loan in a banking application, calculating shipping costs in an e-commerce platform, or deciding which recommendations to display to a user on a streaming service. Effectively designed application logic is crucial for an application's correctness, efficiency, and ability to meet user needs.
