In an entity relationship diagram, an associative entity is depicted by a(n)

Question

BlackTom AI · Accepted Answer

Consider the question about how an associative entity is depicted in an entity-relationship diagram. 
Option 1: oval (ellipse). Ellipses are typically used for attributes, not entities, so this does not represent an associative entity.
Option 2: rhombus (diamond). Diamonds usually denote relationships between entities, not the associative entity itself, so this is not the correct depiction for an associative entity.
Option 3: rectangle. In many ER modeling conventions, an associative entity is shown as a rectangle, sometimes with additional notation to indicate its links to related entities, which aligns with how a standalone or specialized entity is represented.
Option 4: circle. Circles are not used to depict entities or relationships in standard ER diagrams, so this choice is inaccurate.
Given these interpretations, the depiction that matches the concept of an associative entity is the rectangle, making this option the correct one. The incorrect choices misalign with standard diagrammatic conventions by assigning attribute-only, relationship-only, or nonstandard shapes to an associative entity.
