    What is XS?

    • A native, lightweight application server

    • An optional engine to handle excessive data loads

    • A data cleansing engine

    • A user interface

    Correct Answer
    A. A native, lightweight application server

    TRUE OR FALSE: Active/active-read enabled mode allows applications to redirect read-intense workloads to a secondary HANA?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    A secondary read-only HANA is used to continuously capture and replay the database log from a primary HANA. The secondary read-only HANA can then be used for any read-intense tasks, thereby off-loading this work from the primary HANA to balance the workloads and increase overall performance.

    • A set of security permissions that aligns to a user's view of the data.

    Correct Answer
    A. A collection of views in the SAP HANA Studio that are organised by role
    Explanation
    A perspective in SAP HANA refers to a collection of views in the SAP HANA Studio that are organized by role. This means that different users with different roles can have access to different perspectives, allowing them to view and analyze data based on their specific needs and responsibilities. Perspectives help to streamline the user experience and make it more efficient by organizing relevant views in a logical manner.

    What are advantages of column store tables?

    • Data footprint is automatically reduced through compression

    • Only the columns required are actually loaded to memory

    • Columns can be partitioned

    • Aggregates can be created

    Correct Answer(s)
    A. Data footprint is automatically reduced through compression
    A. Only the columns required are actually loaded to memory
    A. Columns can be partitioned
    Explanation
    Column store tables are optimized for read-intense analytical processing, not transactional processing where read and write is needed. They also use automatic compression to reduce the footprint and we only need to load columns that are required into memory. Also, you can partition column tables. You can’t do any of these things with row tables. Refer to HA100 Unit 2, Architecture of SAP HANA, for details.

    To maintain good read performance in a constantly changing database, which two components are used?

    • Column store

    • Memory store

    • Delta storage

    • Main storage

    Correct Answer(s)
    A. Delta storage
    A. Main storage
    Explanation
    To maintain good read performance in a constantly changing database, two components are used: Delta storage and Main storage. Delta storage is used to store the changes or updates made to the database, allowing for efficient retrieval of the most recent data. Main storage, on the other hand, stores the primary data and provides fast access to frequently accessed information. By utilizing both Delta storage and Main storage, the database can effectively handle constant changes while ensuring optimal read performance.
