A Comparison of Leading Database Storage Engines in Support of Online Analytical Processing in an Open Source Environment
<p>Online Analytical Processing (OLAP) has become the de facto data analysis technology used in modern decision support systems. It has experienced tremendous growth, and is among the top priorities for enterprises. Open source systems have become an effective alternative to proprietary systems in …

Text cube: construction, summarization and mining
… of ``data cube'', data cube, associated with online analytical processing (OLAP), has become a driving engine in data warehouse industry. By modeling a large textual corpus as a ``cube'', \ie multi-dimensional and hierarchical structure, we bridge the power of traditional OLAP and Information …

Correlation indices : a new access method to exploit correlated attributes
In relational query processing, one generally chooses between two classes of access paths when performing a predicate lookup for which no clustered index is available. One option is to use an unclustered index. Another is to perform a complete sequential scan of the table. Online analytical …

ONet: Search, explore, and visualize hierarchical topic summarization on Twitter using network-OLAP
Multi-dimensional data is one of the most abundant and publicly available data sources for people to access today. It forms hierarchy naturally(e.g., people publish posts about different topics or share information from various countries. Given a topic such as technology, it many form sub-topics …

Keyword-based object search and exploration in multidimensional text databases
We propose a novel system TEXplorer that integrates keyword-based object ranking with the aggregation and exploration power of OLAP in a text database with rich structured attributes available, e.g., a product review database. TEXplorer can be implemented within a multi-dimensional text database, …

Latency-bandwidth tradeoffs in Internet applications
… applications in two distinct ways. Back-end data processing applications, which need to transfer large amounts of data between data centers across the world, are primarily constrained by the limited capacity of Internet links. Front-end user facing applications, on the other hand, are primarily …

Analytical Query Processing Based on Continuous Compression of Intermediates
… insights from these data, the importance of Online Analytical Processing (OLAP) workloads is constantly growing. At the same time, the hardware landscape is continuously evolving. On the one hand, the increasing capacities of DRAM allow database systems to store their entire data in main …

Integrative text mining and management in multidimensional text databases
… and the system should well support OLAP (online analytical processing) of the text information. This is a big challenge for most existing text mining techniques because of the efficiency and the scalability issues. On the other hand, the huge amount of text information in such databases …

Privacy-preserving data publishing and analytics using data cubes
Data cubes play an essential role in data analysis and decision support. In a data cube, data from a fact table is aggregated on subsets of the table's dimensions, forming a collection of smaller tables called cuboids. When the fact table includes sensitive data such as salary or diagnosis, …
