ER Diagrams (Entity-Relationship Diagrams)

Entity-Relationship Diagrams (ER Diagrams) are visual representations used to illustrate how entities (such as people, places, or things) relate to each other within a system, often used in database design. Each entity is depicted as a rectangle, and relationships between them are shown as lines connecting these rectangles. Attributes, or details about each entity, are represented in ovals. ER Diagrams help in understanding data structures and how different components interact, making them essential for organizing information effectively in various applications, from business databases to software development.
