Big Data and New Data Warehousing Approaches

Big data are a data trend present around us mainly through Internet – social networks and smart devices and meters – mostly without us being aware of them. Also they are a fact that both industry and scientific research needs to deal with. They are interesting from analytical point of view, for they contain knowledge that cannot be ignored and left unused. Traditional system that supports the advanced analytics and knowledge extraction – data warehouse – is not able to cope with large amounts of fast incoming various and unstructured data, and may be facing a paradigm shift in terms of utilized concepts, technologies and methodologies, which have become a very active research area in the last few years. This paper provides an overview of research trends important for the big data warehousing, concepts and technologies used for data storage and (ETL) processing, and research approaches done in attempts to empower traditional data warehouses for handling big data.
