Application Logic

Application logic refers to the core business rules, algorithms, and decision-making processes that define how an application functions and processes data. It represents the 'brains' of the software, implementing the specific requirements and workflows that solve user problems. This logic is distinct from presentation logic (UI) and data access logic, forming the middle layer in a typical application architecture.

Also known as: Business Logic, Domain Logic, Core Logic, App Logic, Program Logic

Why learn Application Logic?

Developers should master application logic to build robust, maintainable software that correctly implements business requirements. It's essential for creating applications that handle complex workflows, enforce business rules, and ensure data integrity. Understanding application logic is particularly important when working with enterprise systems, financial applications, or any software with significant business rules.
