O que é o “Big Data”
"Big data" is
• high-volume,
• high-velocity and
• high-variety
information assets that demand
cost-effective, innovative forms of
information processing for
enhanced insight and decision
making.
 An enhanced insight that leads to improved decision making and value
creation.

Big Data
“80% of data is now unstructured content such as email, videos,
and other user-generated content which must be combined
with structured data to produce the information businesses
need to serve consumers individually.”
Weblogs, social media, server logs, sensores, emails, fotografias.
O crescimento da electrónica de consumo, a baixa de preços continuada
de processadores, armazenamento e comunicações.
Transformação : o potencial destes dados pode agora ser explorado
pelas organizações.
 Aumento do valor estratégico da informação.
“Infonomics is recent term to describe the study and emergent discipline of
quantifying, managing and leveraging information as a formal business asset.”

Big Data
• Volume
Crescimento rápido de dados estruturados, não estruturados, internos e
externos. Ex: Um motor a jacto produz cerca de 10TB de dados em 30 minutos...
• Velocidade
Necessidades de negócio não antecipadas.
Ex: Fluxo de opiniões e relações geradas,
alta velocidade e frequência dos tweets
• Variedade
Vários formatos, diferindo dos tradicionais com taxas de mudança bastante altas.
Novos tipos de dados serão necessários para capturar a informação resultante.
Ex: novos sensores implementados, novas campanhas de marketing executadas
• Valor
Existe pouco valor per se nestes dados.
Ex: Se perdermos 5 minutos das transacções de um cliente numa webstore, não irá
influenciar a analise sobre o seu comportamento.

O papel da tecnologia
• Hadoop project
It is a framework which allows processing of large data sets across cluster of
computers (commodity hardware).
Hadoop MapReduce Its a programming mode which supports parallel processing of
large datasets

"How to Choose the Right Apache Hadoop Distribution" — Vendors offer
Apache Hadoop distributions with preintegrated projects, but different
vendors offer different combinations, at differing release levels.”
“Interest in using Hadoop to solve big data challenges has increased
significantly in the past 12 months. “
“IT architects, business leaders and data scientists involved in "big data"
projects can easily go wrong when they construct an Apache Hadoop
stack, because the 20 or more potential components ("projects") are not
integrated as commercial software packages are.”

IBM Will Boost Analytics Ability by Buying Search Provider Vivisimo
Aster Data Purchase Shows Teradata's Vision Is Deeper Than 'Big Data'
The planned acquisition of Aster Data will give Teradata a distributed data warehouse that
supports unstructured content and more aspects of extreme data than competitors do now.
Netezza Acquisition Will Boost IBM Against Oracle, Teradata
Hadoop Distribution Seeks to Leverage Intel's Microprocessor Strengths
Acquire, organize, and analyze big data
Uncover hidden relationships that lead to new perspectives
Turn analytics into better decision-making
 É fundamental perceber o que os dados significam para a organização.

“Big Data Drives Rapid Changes in Infrastructure and $232 Billion in IT Spending
through 2016
Big data has become a major driver of IT spending. The benefits to organizations
for adding big data to their information management and analytics infrastructure
will force a more rapid cycle of replacing existing solutions.”
