Study Notes
Big Data and Data Science
- Big Data refers to extremely large and diverse collections of structured, unstructured, and semi-structured data that grows exponentially over time.
- It is characterized by its volume, velocity, and variety, making it difficult for traditional data management systems to store, process, and analyze.
- Big Data is used in machine learning, predictive modeling, and other advanced analytics to solve business problems and make informed decisions.
Motivation and Applications
- Big Data has given organizations a new way to analyze and visualize their data effectively.
- Examples of its applications include:
- Business: Customer feedback, trends, etc.
- Health: Healthcare organizations use big data technology to capture patient information and get a complete view for insight into care coordination, health management, and outcome.
Benefits of Big Data Analytics
- Organizations can use big data analytics systems and software to make data-driven decisions that can improve business-related outcomes.
- Benefits include:
- More effective marketing
- New revenue opportunities
- Customer personalization
- Improved operational efficiency
- These benefits can provide competitive advantages over rivals.
