ITPEC IP October 2021 Question 28
ITPEC IP October 2021 — Question 28 of 100
An E-R diagram consists of entities and relationships, and it is used as the basis for designing relational tables. Therefore A is relationships, B is E-R diagram, and C is tables, which is exactly combination (c).
Answer (c)
Why not others:
- instances are individual occurrences of entities, not the connector concept paired with entities in an E-R model
- a flowchart represents processing flow rather than the conceptual structure of business data
- relational design produces tables, not functions
Key rule: Conceptual data modeling identifies entities and their relationships in an E-R diagram, which is then transformed into a relational table design.
