Quizplus · Accepted Answer

An ERD (Entity-Relationship Diagram) is a tool used in database design to visually represent the relationships between entities in a system. It shows the attributes of each entity and the relationships between them, allowing developers to easily understand the overall structure of the database. UML (Unified Modeling Language) is a more general-purpose modeling language that can be used for a variety of systems, not just databases. Data source and RUP (Rational Unified Process) are not relevant to this question.
