解説

問 28

  • ア

    正解 The correct answer is ア “Big Data.” The phrases “large volume”, “a wide variety of formats”, and “real-time” in the question correspond directly to the three Vs that characterize big data, namely Volume, Variety, and Velocity. Big data refers to a body of data so large, diverse, and rapidly generated that traditional methods cannot handle it; analyzing such data is expected to yield insights useful for decision-making. The wording of the question is the very definition of big data, so ア is the most appropriate.

  • Incorrectイ

    “Diversity” means variety, referring to a people- and organization-management concept of making the most of talent that differs in gender, nationality, age, values, and so on. It is not a term about the volume or format of data, so it is incorrect.

  • Incorrectウ

    “Core competence” is a management-strategy term referring to a company’s unique core strength (such as technology or know-how) that competitors cannot easily imitate; it is not a term that describes the characteristics of data, so it is incorrect.

  • Incorrectエ

    “Crowdfunding” refers to a fundraising mechanism that gathers small amounts of money from a large, unspecified number of people via the Internet. It has nothing to do with the meaning of information useful for decision-making, so it is incorrect.

ここがポイント
  • The three Vs of big data: Volume, Variety, and Velocity. Analyzing data that has these characteristics yields insights useful for decision-making.
  • Be able to distinguish its meaning from easily confused management/IT terms (Diversity, Core competence, Crowdfunding).
