    Which OLAP operation involves focusing on a subset of

    dimensions (e.g., region=‘Asia’)?
    A Roll-up Correct Answer Incorrect Answer
    B Drill-down Correct Answer Incorrect Answer
    C Slice Correct Answer Incorrect Answer
    D Dice Correct Answer Incorrect Answer
    E Pivot Correct Answer Incorrect Answer

    Solution

    Slice reduces the cube by fixing one dimension value (like filtering rows in SQL). Dice filters multiple values, roll-up aggregates, drill-down goes deeper into hierarchy, pivot rotates.
