The purpose of the Trips-R-You Flight Booking Case Study is to provide an integrated, end-to-end set of requirement examples. In IIBA® BABOK® V3 terminology, end-to-end means from Business Requirements to Stakeholder Requirements to Solution and Transition Requirements. This case study, and associated artefacts, use the more traditional business terms Goals, High-level Requirements (HLRs), and Detail Requirements. Only functional requirements are addressed, and only within the context of a project chartered to deliver an IT-based solution.

Section 3 begins by presenting one additional tool - a Data Dictionary. As the detail for a given HLR is discussed, the data-specific business needs involved are captured using this tool. The idea is to add entries about record types and fields (i.e. entities and attributes) the first time their need is discussed (e.g. an HLR for a specific screen or report). Once captured, those data-specific details are available for reference when those needs come up again, as they will, during discussions involving other HLRs. The detail in the data dictionary is shown to support a transition requirement for a new or updated database schema.
