Understanding Big Data
Definition and Scope
Big data means a huge volume of data that is generated every day from various sources such as social media, internet searches, and online transactions. The data is usually unstructured and requires advanced tools and techniques to analyze and extract insights from it. Big data is characterized by the different Vs: volume, velocity, and variety.
- Volume: Big data is characterized by its sheer volume. The amount of data generated every day is massive and requires specialized tools and techniques to manage and analyze it.
- Velocity: Big data is generated at an incredible speed. The data is constantly being created and updated in real-time. It means that the data needs to be processed and analyzed quickly to extract insights from it.
- Variety: Data can be structured or unstructured, and it can come from a variety of sources such as social media, internet searches, and online transactions.
Some key components of big data are given here:
- Data Storage: Big data requires specialized storage solutions to handle the large volume of data that is generated every day. It includes technologies such as Hadoop and NoSQL databases.
- Data Processing: Big data requires specialized tools and techniques to process and analyze the data. MapReduce, Spark, and Hive are used for this purpose.
