    Question

    In a Data Analytics pipeline, which of the following is an advantage of using Dimensional Modelling?

    A Better normalization of data Correct Answer Incorrect Answer
    B Provides flexibility in transaction processing Correct Answer Incorrect Answer
    C Makes data querying easier and faster for analytical tasks Correct Answer Incorrect Answer
    D Reduces data redundancy Correct Answer Incorrect Answer
    E Enables efficient real-time data processing Correct Answer Incorrect Answer

    Solution

    Dimensional Modelling simplifies data analysis by structuring data into fact and dimension tables. This star or snowflake schema allows for easier and faster querying, particularly for OLAP systems, by optimizing data retrieval. Why Other Options are Wrong: a) Dimensional modeling is not focused on normalization, which is a feature of relational modeling. b) Transaction processing is more efficient in normalized databases, not dimensional ones. d) Dimensional models may introduce some data redundancy due to denormalization. e) Dimensional modeling is designed for analytical queries, not real-time data processing.
