Big Data Era
A survey of VA systems
provide overview of the state-of-the-art
stimulate innovative ideas
avoid redundant effort
What is available
survey of open source tools
survey of BI tools
What is missing
comparison of commercial VA tools
Our Goal
Complementing existing surveys
An encompassing survey of commercial VA systems
functional comparison
benchmark system performance
Provide recommendations to potential users
Identify future directions for VA system development

Conclusions
Workflow
Identify relevant commercial systems
study current market share, select systems in different
categories, assign priority level for each system
Design structured questionnaire for functional
comparison
Analyze functional comparison result
Further investigation on top-priority systems
system stress test, test against benchmark data
In this paper…
We report our findings on the systems
15 systems in the initial list
Tableau, Spotfire, QlikView, JMP (SAS), JasperSoft, ADVIZOR Solutions,
Board, Centrifuge, Visual Analytics, Visual Mining
Cognos(IBM), SQL Server BI (Microsoft), Business Objects (SAP), Teradata,
PowerPivot (Microsoft)
10 answered our questionnaire (in green)
Some additional text analysis systems investigated
nSpace (Oculus), Palentir, and In-Spire (PNNL)
