- CASE STUDY
What is Big Data?
Big data is being generated by everything around us at all times. Every digital process and social media exchange produces it. Systems, sensors and mobile devices transmit it. Big data is arriving from multiple sources at an alarming velocity, volume and variety. To extract meaningful value from big data, you need optimal processing power, analytics capabilities and skills.
Data Volume Trend
1.Describe the kinds of “big data” collected by the organizations described in this case.
British Library: It collects data from typical library resources like books, periodicals, and newspapers. In addition, it must store and collect data from Web sites that no longer exist but must be preserved for historical purposes. Data from over 6 billion searches must also be stored.
Law enforcement agencies: Collect data on criminal complaints, national crime records, and public records.
Vestas Wind Energy: Collects data from 43,000 turbines in 66 countries; collects location-based data to help determine the best location for turbines; currently stores 2.8 petabytes of data and includes approximately 178 parameters, such as barometric pressure, humidity, wind direction, temperature, wind velocity, and other company historical data; plans to add global deforestation metrics, satellite images, geospatial data, and data on phases of the moon and tides.
Hertz: Gathers data from Web surveys, emails, text messages, Web site traffic patterns, and data generated at all of Hertz’s 8300 locations in 146 countries.
New text-mining software described in the case can shorten data analysis to hours or minutes and produce
better results. Businesses can react faster to solve problems, satisfy customers, and change work
processes. Managers can detect emerging issues and pinpoint troubled areas of the business at many different managerial levels. Managers can discover patterns and relationships in the data and summarize the information more quickly and more easily thereby saving time and
money.
The British Library and Vestas use Hadoop so it can process large amounts of data quickly and efficiently. Hertz uses sentiment analysis to determine customer
satisfaction. Law enforcement agencies use Web mining techniques to help determine potential criminal acts.
They also use analytics to predict future crime patterns.
2. List and describe the business intelligence technologies described in this
case.
3.Why did the companies described in this case need to maintain and analyze big data? What business benefits did they obtain?
The British Library is able to maintain historical records of events and
provide users with more information about its past.
It can now process information requests more
quickly and easily. The technology it uses provides
an insight engine that helps extract, annotate, ad
visually analyze vast amounts of unstructured Web data, delivering the
results via a Web browser.
Criminals and criminal organizations are
increasingly using the Internet to coordinate and perpetrate their crimes.
New tools allow agencies to analyze data from a wide
array of sources and apply analytics to predict future
crime patterns.
Vestas is able to collect more data that can reduce
the resolution of its grid patterns from 17 x 17 miles to 32 x 32 feet to establish exact wind flow patterns at particular locations. That
further increases the accuracy of its turbine
placement models.
Hertz stores all of its data centrally instead of within
each branch, reducing time spent processing data and
improving company response time to customer feedback and changes in
sentiment.
4. Identify three
decisions that were improved by using “big
data.”
Vestas used its big data to help find the best places to install its wind turbines. It is able to manage and analyze location and weather data with models that
are much more powerful and precise. The new technology enables the company to forecast optimal
turbine placement in 15 minutes instead of three weeks, saving a month of development time for a turbine site and enabling customers to achieve a
return on investment much more quickly.
Hertz used it data analysis generated from different sources to determine the cause of delays at its
Philadelphia locations and adjusted staffing levels during peak times and ensuring a manager was
present to resolve any issues.
Law enforcement agencies use their data analysis to predict future crime patterns and become more proactive in its efforts to fight crime and stop it
before it occurs.
5. What kinds of organizations are most likely to need “big data” management and analytical tools? Why?
Organizations that have an active presence on the Web
or on social media sites need to use big data management
and analytical tools to process the numerous
unstructured data that can help them make better, more timely decisions. Businesses that generate big data from
manufacturing, retailing, and customer service need the
tools that the technology can provide.
