Using BW powered by SAP HANA, you can find the following benefits −
Excellent performance in analytical reporting and data loading using HANA in memory database capabilities. All BW functions performed in SAP HANA benefits from in-memory database and calculation engines for faster data processing.
With HANA optimized objects, you can perform complex queries, detailed analysis, high data volume, and aggregations efficiently.
All existing BI tools such as BEx, Business Objects BI reporting tools, and Microsoft Excel are directly supported by SAP BW on HANA.
SAP HANA provides high level of data compression. Column storage of tables requires less storage type and hence provides lower Total Cost of Ownership (TCO).
Business Warehouse Accelerator (BWA) is not required while using HANA underneath BW.
You don’t need aggregated tables and HANA supports on-the-fly aggregations.
It has simplified data modeling by using in-memory-optimized objects. There is no need to load BWA index.
