Business Requirement: what the needed achievements will be for a service or system, and the quality measures in order to preform some operational aspect of the organization. These are usually expressed in terms of broad outcomes the business requires, rather than specific functions the system may perform. These are not technical or functional, rather are specific to business processes. Note that the business requirements often can be broken up into sub-business requirements and many functional requirements.
Dupe: When someone requested more than one program in the same campus (Marketing). Can also be short for "duplicate", meaning more than one.
Functional Requirements: Descriptions of what the service or system must do in order to fulfill the business requirements. Note that the business requirements often are broken up into sub-business requirements and thus many functional requirements.
