We ve covered business use case models this week. A business use case defines what happens in the business when the use case is requested by a business actor; it describes the complete workflow or business process that produces results required or in need of a business actor. Use case behaviors may be described in a natural language text, which is current common practice, or by using UML behavior diagrams for specific behaviors such as:- activity,- state machine, and- interaction.For this assignment, you are asked to create a business use case diagram for a restaurant. Include several business actors with needs and goals as related to the restaurant and business use cases, expressing expectations of the actors from the business. Your diagram should include both external and internal business views of the restaurant.For assistance in completing this activity, please review this business use case guideline document:https://sceweb.uhcl.edu/helm/RationalUnifiedProcess/process/modguide/md_buc.htmPlease paste your diagram to a Word document; then, submit it for grading.
