Can you explain what is meant by the term 'business logic' in software development?

Business logic is the part of the software that implements rules and processes specific to the application's domain. It is responsible for data processing, decision-making, and executing operations that reflect real business requirements. For example, in an online store, business logic may include checking stock availability, calculating discounts, and forming orders.

Business logic is separated from technical aspects such as the user interface or database operations to make the code more understandable and maintainable.
