P-ETL: Parallel-ETL based on the MapReduce paradigm

2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA), 2014
Big data is an opportunity in the emergence of novel business applications such as “Big Data Analytics” (BDA). However, these data with non-traditional volumes create a real problem given the capacity constraints of traditional systems. The aim of this paper is to deal with the impact of big data in a decision-support environment and more particularly ...
