What is Big Data?
- Big data is when the volume, velocity, and variety of data exceed an organization's storage or computation capacity for accurate, timely decision-making.
- Sources of Big Data include hospital patient registries, electronic point-of-sale data, telephone calls, website hits, bank transactions, catalog orders, remote sensing images, airline reservations, web comments, tax returns, credit card charges, and sensor data.
Consequences of the Data Deluge
- Every problem, eventually, generates data.
- Every company and individual eventually needs analytics.
Big Data
- Big data is when the cost of storing information becomes less than the cost of making the decision to throw it away.
Big Data: What is it?
- Big data is the point where the volume, velocity, and variety of data exceed an organization's capacity to store and process the data in a timely manner for accurate decision-making.
Factors associated with big data
- Data volume
- Data velocity
- Data variety
- Data variability
- Data complexity
Data Volume
- Data volumes are increasing due to social media (Facebook, Twitter, Instagram) usage, machines talking to each other, improvements in manufacturing (quality control), automated tracking devices, and streaming data feeds.
Data Velocity
- Business processes are increasingly automated.
- Mergers and acquisitions increase data velocity.
- Social media usage increases data velocity.
- Integration of self-service applications increases data velocity.
Data Variety
- Structured data, unstructured data, business applications, unstructured text documents (articles, blogs), emails, digital images, videos, audio clips, streaming data, stock ticker data, RFID tag data, and sensor data are all data sources.
Data Variability
- The flow of data changes over time (e.g., seasonality, peak response, social media trends).
- Data values change over time.
- Data values differ across data sources.
- Data is stored in different formats.
- Data standards change across time.
Data Complexity
- Data comes from a variety of systems and formats, making it difficult to merge, clean, and transform data uniformly.
What is Analytics?
- The importance of big data isn't the volume of data but how it is used.
- Analytics is the scientific process of transforming data into insight to create better decisions, and opportunities for a competitive advantage.
Levels of Analytics
- Different levels of analytics, from descriptive to predictive to prescriptive.
- Data science experience, advanced analytics, and software engineering support end-to-end analysis of large and diverse data sets.
- Communication with stakeholders is key.
Analytic Methods
- Descriptive models help understand what happened.
- Predictive models predict future outcomes based on historical data.
- Prescriptive models suggest optimal decisions based on predictions.
Glossary of Terms
- Various data-related terms like Statistics, Data Mining, Machine Learning, Artificial Intelligence, Natural Language Processing, Computer Vision, Deep Learning.
Reasons for the Big Data Explosion
- Increasing data velocity due to streaming data feeds, point-of-sale systems, RFID tags, smart metering, increases in cheap data storage, social media, automated business processes, mergers, and online self-service applications.
Factors Driving Demand for Big Data Solutions
- Increasing data growth rates.
- Availability of data from social media.
- Demand for mobile business intelligence.
- Increased need for real-time reporting.
- Desire to analyze social media sentiment.
Data Science
- Data systems, business intelligence, machine learning, business acumen, math, or statistics are all part of data science.
- A data scientist is deep in one or two areas.
Big Data Tools
- Hadoop, Storm, Spark, Hive, Tableau, R, Python, and SAS are example tools.
R
- R is a language and environment for statistical computing and graphics.
Hadoop
- Hadoop is a popular big data ecosystem designed for highly scalable computations, from a single server to a cluster of thousands of machines.
Python
- Python is a versatile, high-level programming language used in various fields like web development, game development, machine learning, data science, data visualization, web scraping, and more.
Tableau
- Tableau is a data visualization tool for business intelligence allowing creation of interactive graphs, charts, dashboards, and worksheets to gain insights.
