    BODS is a ETL tool , you can bring needed data selectively from different sources ( including selected columns of different tables ) , cleanse it . You can use BODS for capturing Slowly Changing dimensions . But in the end - all it does is DATA TRANSFER .

    Extract from source , transform/cleanse and then load into data warehousing tables.

    TO model the data for reporting purposes , you need to do dimension modeling (and entity modeling) , and that's done in HANA studio.

    BODS brings the data and loads it in the HANA Database tables .

    The dimensional model ( i.e in a simple case of star schema consisting of a central fact table and associated dimension tables) is realised by attribute views and analytical views . The dimension tables can be thought of attribute views and the fact table connecting the dimension tables in a star schema can be thought as the analytical view . The analytic view can be thought as the final infocube.

    and HANA is the in memory database that efficiently stores the Data .

    Dear Manoj,

    HANA is consider as real time Modeling , so SAP provides currently SLT, ETL, Event replicators.

    if you want to do clensing, checking.. all concept ETL concepts use

    BODS or BW on HANA

    thanks
