Online Analytical Processsing on Graph Data [PDF]

open access: yesarXiv, 2019
Online Analytical Processing (OLAP) comprises tools and algorithms that allow querying multidimensional databases. It is based on the multidimensional model, where data can be seen as a cube such that each cell contains one or more measures that can be aggregated along dimensions. In a Big Data scenario, traditional data warehousing and OLAP operations

Micro-architectural Analysis of OLAP: Limitations and Opportunities [PDF]

open access: yesarXiv, 2019
Understanding micro-architectural behavior is profound in efficiently using hardware resources. Recent work has shown that, despite being aggressively optimized for modern hardware, in-memory online transaction processing (OLTP) systems severely underutilize their core micro-architecture resources [25]. Online analytical processing (OLAP) workloads, on

Towards the Next Generation of Data Warehouse Personalization System: A Survey and a Comparative Study [PDF]

open access: yesIJCSI International Journal of Computer Science Issues, Vol 9, Issue 3, No 2, May 2012, pages 561-568, 2012
Multidimensional databases are a great asset for decision making. Their users express complex OLAP (On-Line Analytical Processing) queries, often returning huge volumes of facts, sometimes providing little or no information. Furthermore, due to the huge volume of historical data stored in DWs, the OLAP applications may return a big amount of irrelevant
