| Pig | A high-level scripting language for easily writing data flows |
| Hive | Provides a SQL-like query language to facilitate data analysis |
The Three Vs of Big Data: Volume, Variety, Velocity
Big Data is generally defined by three Vs: Volume, Variety, and Velocity. Volume refers to the vast amounts of data, Variety indicates the complexity of data generated from diverse sources, and Velocity denotes the rapid rate at which data is created and processed. These three elements pose key challenges for Big Data analysis and management, driving the development of various technologies and methodologies to handle them effectively.
| V | Description |
|---|---|
| Volume | Storage and management of large-scale data |
| Variety | Diverse data formats, including structured and unstructured data |
| Velocity | The fast pace of real-time data generation and processing |
| Veracity | Maintaining data accuracy and reliability |
| Value | The business and insight value derived from data |
