What is BIG DATA

brillianttyagi July 5, 2022

Big data means a collection of data sets which are large and complex that describe a massive volume of both structured and unstructured data which makes it difficult to process using traditional database and software techniques.
The challenges would include analysis, curation, capture, search, sharing, storage and privacy violations.

Types of big data?

Big data could be of three types:

  1. Structured data:The data that can be stored and processed in a fixed format is called as Structured Data. Data stored in a relational database management system (RDBMS) is one example of ‘structured’ data. It is easy to process structured data because of fixed schema. Structured Query Language (SQL) is often used to manage such kind of Data.
  2. Semi-Structured data:Semi-Structured Data is a type of data which does not have a any formal structure of a data model, i.e. a table definition in a relational DBMS, but nevertheless it has some organizational properties like tags and other markers to separate semantic elements that make it easier to analyze. HTML files or JSON documents are examples of semi-structured data.
  3. Unstructured data:The data which have unknown form and cannot be stored in RDBMS and cannot be analyzed unless it is transformed into a structured format is called as unstructured data.
    Unstructured data files habitually include text and multimedia content which does not have any particular internal structure.For example: e-mails, videos, audio files, photo and many other types of business documents.

Examples of big data?

Daily we are uploading millions of bytes of big data and big data is growing exponentially.90% of big data is created in last two years.

Applications of big data?

In today’s generation big data is used everywhere and In fact we are in the technology generation where new technology came in just one month or two months.
