Defining Big Data
Characteristics of Big Data (Volume, Variety, Velocity, Veracity, Value) Big Data is defined by its five key characteristics:
- Volume: The sheer amount of data generated.
- Variety: The different types of data (structured, unstructured).
- Velocity: The speed at which data is generated and processed.
- Veracity: The uncertainty and quality of data.
- Value: The potential value that can be derived from data.
Examples of Big Data Examples of Big Data include social media interactions, online transaction records, and sensor data from IoT devices.
Defining Data Science
Key Components of Data Science (Data Mining, Machine Learning, Statistical Analysis) Data Science encompasses a variety of techniques and tools aimed at analyzing and interpreting complex data. Key components include:
- Data Mining: The process of discovering patterns in large datasets.
- Machine Learning: A subset of artificial intelligence that enables systems to learn from data.
- Statistical Analysis: The application of statistical methods to understand data trends.
The Role of a Data Scientist Data Scientists play a critical role in translating Big Data into actionable insights, using their skills in programming, statistical analysis, and domain expertise.
