In the Big Data warehouse context, a column-oriented NoSQL database system is considered as the storage model which is highly adapted to data warehouses and online analysis. Indeed, the use of NoSQL models allows data scalability easily and the colum

Hadoop uses horizontal partitioning to improve the performance of a big data warehouse. A major challenge when horizontally partitioning the tables of a big data warehouse is to reduce network traffic for a given workload. A common technique to avoid

Horizontal partitioning techniques have been used for many purposes in big data processing, such as load balancing, skipping unnecessary data loads, and guiding the physical design of a data warehouse. In big data warehouses, the most expensive opera

Horizontal partitioning is an optimization technique applied to improve query processing time in distributed data warehouses. Scanning a large number of HDFS data blocks, to respond to the ad-hoc or OLAP queries, is a heavy operation. We can skip loa

Current data warehousing and On-Line Analytical Processing (OLAP) systems are not yet particularly appropriate for textual data analysis. It is therefore crucial to develop a new data model and an OLAP system to provide the necessary analyses for tex
