  • Abstract


    Designing a Data warehouse is the main mission done by DBA; Testing the data warehouse performance efficiency is also done while going to production. Actually, hardware has developed in term of memory volume, speed and storage, but for the specialists, the objective is still to minimize the execution time and the storage space. The paper shows that using bitmap index and partitioned fact tables in big data warehouses volumes based on a snowflake schema is advantageous based on query execution time.
