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

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
