External data sources (EDSs) being integrated in a data warehouse (DW) frequently change their data structures (schemas). As a consequence, in many cases, an already deployed ETL workflow executes with errors. Since structural changes of EDSs are frequent, an automatic reparation of an ETL workflow after such changes is of a high importance.

P-ETL: Parallel-ETL based on the MapReduce paradigm
2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA), 2014Big 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 ...

In the first decade of the 21st century, the terms data warehouse and data mart were suddenly—and without warning—copied and pasted all over every database professional’s resume. Despite the apparent increased awareness in the professional community, the core components of these structures, dimension and fact tables, remained misunderstood.

Out of the various duties assigned to the ETL project manager or architect, one of the most critical is the establishment of a project estimate. When considering a new project of any type, executives, managers, and other decision makers will ask first, “How long will it take?” Appropriately setting time frame expectations is critical to the success of ...
