To cover this need, VF NL recently implemented Tableau as a new BI tool for Data discovery & Visualisation. In this presentation, you will learn - Why VF NL chose Tableau - How VF NL is using Tableau together with the Teradata datawarehouse - How VF NL is using Tableau and Teradata to make the right business decisions

Choosing a Data Discovery
& Visualisation tool
Why we needed a Data Discovery & Visualisation tool
Growing demand from business end users for interactive and visual
data exploration, but:
• Current BI tools did not have sufficient functionality
• Current BI tools were not user friendly
• Result: increasing workload for BI teams, delivered reports triggered
new requests etc.
Reason: we were not answering the real underlying question:
Insert Confidentiality Level on title master
What do I
need to do to
improve my
business?
Target group
Data Discovery/Visualization is not for everyone. It’s mainly aimed at Business users
- With analytical skills
- With an interest to further explore and analyze data
- Without BI knowledge
Possible jobs/roles that can benefit from Data Discovery:
• Business managers
• Business analysts
• Process managers
• Marketeers
• Sales managers
• Controllers
High level requirements for a data explorer tool
• The tool has to be able to process large amounts of data quickly
• The tool has to be able to run on existing BI infrastructure (including live connection to
EDW)
• The tool should be able to retrieve and combine data from different sources
• The tool has a user friendly, intuitively designed interface
• The tool has user friendly filtering, downdrilling and slicing/dicing functionalities
• The tool has an abundance of easy to use visualization functionalities
• The tool can be used to create interactive dashboards
• Dashboards and analysis can be saved, shared and scheduled to be refreshed
• The tool has an export functionality (Excel, CSV, Picture etc.)
• The tool must be able to run on tablets (Mobile BI)
Vodafone chose Tableau as the best tool
What we liked about Tableau:
• Implementation speed
• User interface
• Great performance with huge datasets
• Excellent online learning & training material (free)
• Strong Visualisation functions
• Excellent customer support
Currently 20 Desktop licenses and >100 server interactors
Combining Tableau and
Teradata
Connecting Tableau to Teradata (or any other source)
Native Teradata connector:
• Optimized connection
• Drag & Drop querybuilder or custom SQL
Importing data vs live connection
• Importing data (extract) used for
large datasets
• Great performance, even with
modest hardware
• Extracts can be scheduled on server
• Extracts on server can be shared
Using Tableau to make
the right Business
decisions
Use case 1: 4G Network rollout planning
• Plotted revenue per
network cell on map
• Identified high value area’s
• Used this information for
rollout planning of 4G
