Which of the following is NOT true?

Select one answer.

BlackTom AI · Accepted Answer

The question asks which statement is NOT true, but the provided data lacks the list of answer options to evaluate.
The only item present is in the 'answer' field: "E/R diagrams are used to represent a logical model." Since the task is to identify the NOT true statement from the options, we would normally compare all options and determine which one contradicts established concepts.
Regarding the content we do have: in database modeling, ER (Entity-Relationship) diagrams are traditionally used to represent conceptual schemas, capturing high-level entities, relationships, and attributes without getting into implementation details. While ER models can be mapped to logical schemas (and in some contexts are translated into a logical design), the core purpose of ER diagrams is commonly described as conceptual modeling rather than strictly logical modeling. Therefore, the claim that ER diagrams are used to represent a logical model is not the primary or typical characterization; it is more accurate to say they represent a conceptual model (and can be transformed into a logical model). This nuance supports the idea that the statement could be considered NOT true in many educational contexts, though some curricula may describe mappings to logical schemas.
However, because the list of all answer options is missing, we cannot evaluate why other potential statements might be true or false, nor compare alternatives to solidify which one is NOT true in this specific question.
In short: the available item suggests the statement might be false since ER diagrams are conventionally seen as conceptual, not strictly logical. The absence of the other options prevents a complete, option-by-option analysis as required.
