Abstract: Big Data emerged after a big explosion of data from the Web 2.0, digital sensors, and social media applications such as Facebook, Twitter, etc. In this constant growth of data, many domains are influenced, especially the decisional support system domain, where the integration of processes should be adapted to support this huge amount of data to improve analysis goals. The basic purpose of this research article is to adapt extract-transform-load processes with Big Data technologies, in order to support not only this evolution of data but also the knowledge discovery. In this article, a new approach called Big Dimensional ETL (BigDimETL) is suggested to deal with ETL basic operations and take into account the multidimensional structure. In order to accelerate data handling, the MapReduce paradigm is used to enhance data warehousing capabilities and HBase as a distributed storage mechanism. Experimental results confirm that the ETL operation performs well especially with adapted operations.
