Business Logic

Business Logic is the set of rules that defines how an application behaves and makes decisions. It turns business policies, for things such as pricing, approvals, and eligibility, into consistent software actions.

Business Logic sits between the user interface (web pages, mobile apps) and the data layer (databases and services). It ensures the same calculations and validations occur regardless of which screen, device, or integration is used. When Business Logic is well-designed, it makes systems easier to change, test, secure, and audit.
