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
