Business logic refers to the set of rules, processes, and constraints that govern how an organization operates and achieves its objectives. It dictates how data is created, stored, displayed, and manipulated within an application or system to reflect real-world business operations. This logic ensures that software functions align with business requirements, enabling efficient and accurate decision-making. For instance, in an e-commerce system, business logic would define how discounts are applied during checkout or how inventory levels are updated after a purchase. It is distinct from technical implementation details, focusing instead on the 'what' and 'why' of a process rather than the 'how'. Understanding business logic is crucial for roles covered in certifications like PMP, CAPM, and PMI-ACP, as it underpins effective project management and system design.
