User interfaces and system interfaces differ in that system interfaces involve minimal human intervention for inputs and outputs, while user interfaces require user interaction. The user interface is perceived as the system itself by end users, encompassing physical, perceptual, and conceptual aspects like physical devices and how the system is used. User-Centered Design places the user at the core of the development process, emphasizing understanding user styles, usability evaluation, and iterative development based on user requirements. Human-Computer Interaction (HCI) evolved from human factor engineering and received significant contributions from Xerox, leading to advancements in usability and GUI development. Metaphors for HCI include desktop (objects on a desk), document (data entry on electronic documents), and dialog (interaction through sending and receiving messages). Designing interactive interfaces should follow principles like visibility (controls should be visible and provide feedback) and affordance (control appearance should suggest functionality). Dialog designs are documented through various means like use case descriptions, storyboards, UML diagrams (class, sequence), ensuring a structured and user-friendly interface. Web design principles include placing the organization's logo on every page, providing search functions for large sites, and designing for accessibility for diverse user groups. Designing dialogs involves coordinating user-interface design with processing design, refining forms, and iteratively modifying designs to meet user needs effectively. Database management systems are crucial for storing, retrieving, and managing data, with detailed models derived from domain class diagrams and implemented using relational or object-oriented models.
