Q & A

What is Big Data Analytics?
-Big Data Analytics refers to the methods, tools, and applications used to collect, process, and derive insights from large, varied, high-volume, and high-velocity datasets, which can be both structured and unstructured.
What are the characteristics of Big Data Analytics?
-Big Data is often described by the 'Five Vs': Variety (different types and formats of data), Velocity (the speed at which data is generated), Volume (the amount of data), Veracity (uncertainty and inconsistency in data), and Value (the insights derived from the data).
Why is Big Data Analytics important for companies?
-Big Data Analytics helps companies optimize their business by improving decision-making, enhancing customer experiences, and increasing operational efficiency. It enables businesses to gain valuable insights from data that were previously too vast and complex to analyze manually.
What are some real-world examples of Big Data Analytics being used by companies?
-Amazon uses Big Data to optimize product recommendations and dynamic pricing, Netflix leverages data to improve user retention and engagement, and Marriott uses customer data for personalized service through facial recognition and AI-driven product recommendations.
How does Big Data help in business expansion?
-Big Data helps businesses expand by identifying trends, improving customer satisfaction, and optimizing operations. For example, Uber Eats expanded into food delivery using insights from Big Data, even in a saturated market, by predicting driver availability and delivery speed.
What are some tools used in Big Data Analytics?
-Common tools used in Big Data Analytics include: Hadoop (data storage and processing), Apache Spark (real-time data processing), Talend (data integration), MongoDB (NoSQL database), and Apache Pig (data analysis platform).
What are the different types of Big Data Analytics?
-The four main types of Big Data Analytics are: Diagnostic Analysis (understanding why something happened), Descriptive Analysis (what is happening now), Prescriptive Analysis (what actions should be taken), and Predictive Analysis (forecasting future outcomes).
What skills are necessary for a career in Big Data Analytics?
-Key skills for Big Data Analytics include analytical and problem-solving abilities, knowledge of business domains and Big Data tools, programming skills in languages like Java and Python, familiarity with data warehousing, and understanding cloud computing infrastructure.
What is the role of predictive analysis in Big Data?
-Predictive analysis uses historical data to forecast future outcomes. In Big Data, this involves predicting trends like sales forecasting, customer behavior, and risk assessment to guide business decisions and strategy.
How is data processed in Big Data Analytics?
-Data processing in Big Data involves stages such as data collection, categorization, cleaning, and analysis. This may include batch processing (processing large data sets in bulk) or stream processing (real-time processing of data as it arrives).
