Question 6 In order to make it easier to compare the relation scheme diagram to the UML diagram, we (check all that apply): ✓ If we realize that we forgot any attributes, we just add them in to the relation scheme diagram. ✔The order of the attributes in the relation scheme mirrors the order in the UML class. Name the relation schemes the plural form of the UML class name. Attribute names in the relation scheme diagram use snake_case.

Requirement Analysis

A process that determines the user expectations for a software product is called requirement analysis. In software engineering, requirement analysis is known as requirement engineering. It involves communication with end-users and stakeholders to determine whether the system or software requirements are validated, conflicts are solved, and key requirements are documented. The first activity of the Software Development Life Cycle (SDLC) is requirement analysis.
