Big data refers to the large, diverse sets of information that grow at ever-increasing rates. It encompasses the volume of information, the velocity or speed at which it is created and collected, and the variety or scope of the data points being covered.
Where does it come from?
- The bulk of big data generated comes from three primary sources: social data, machine data and transactional data.
- Social data comes from the Likes, Tweets & Retweets, Comments, Video Uploads, and general media that are uploaded and shared via the world’s favorite social media platforms.
Big data analytics is a field that treats ways to analyze, systematically extract information from, or otherwise deal with data sets that are too large or complex to be dealt with by traditional data-processing application software.
Big Data Analytics training defines Data types involved in Big Data analytics are many: structured, unstructured, geographic, real-time media, natural language, time series, event, network and linked. It is necessary here to distinguish between human-generated data and device-generated data since human data is often less trustworthy, noisy and unclean.
Big Data can be defined by one or more of three characteristics, the three Vs: high volume, high variety, and high velocity.
Examples of Big Data generation includes stock exchanges, social media sites, jet engines, etc.
Data mining of Big Data is achieved by using AI programming that works with algorithms to find patterns in the Big Data that are noteworthy. This provides insights that help management make better-informed decisions.
As data sets continue to grow, and applications produce more real-time, streaming data, businesses are turning to the cloud to store, manage, and analyze their big data. Big data analytics helps organizations harness their data and use it to identify new opportunities. That, in turn, leads to smarter business moves, more efficient operations, higher profits and happier customers.
Big data training helps one understand how to analyze data. There are a number of big data tools available in the market such as Hadoop which helps in storing and processing large data, Spark helps in-memory calculation, Storm helps in faster processing of unbounded data, Apache Cassandra provides high availability and scalability of a database, MongoDB provides cross-platform abilities.
According to Wikibon, the big data analytics market (BDA) is expected to reach $49 billion with a compounded annual growth rate (CAGR) of 11%. So, each year, the market will gain $7 billion in value. As a result of this forecast, the BDA market should reach $103 billion by 2023.
Data skills are so in-demand, they’re becoming increasingly useful in a number of fields—not just technology and finance. Marketing, human resources, sales, and customer service are just a few areas where your expertise can make a big difference to your job performance.
