Big Data is a term used to describe data sets that are too large or complex to be handled by traditional data-processing software. It’s a data set that’s so large and complex that no traditional Data Management tools can effectively store or process it.

Big Data has the following characteristics:

  • Volume: The term “Big Data” refers to a massive amount of information. The size of data is extremely important in determining its value. Furthermore, whether or not a piece of data can be classified as Big Data is determined by its volume. As a result, when dealing with Big Data solutions, ‘Volume’ is an important factor to consider.
  • Variety: Variety refers to a wide range of data types and sources, both structured and unstructured. Most applications used to consider spreadsheets and databases as their only sources of data. Emails, photos, videos, monitoring devices, PDFs, audio, and other types of data are now considered in analysis applications. This wide range of unstructured data poses challenges for data storage, mining, and analysis.
  • Velocity: ‘Velocity’ refers to the rate at which data is generated. The true potential of data is determined by how quickly it is generated and processed to meet demands. The rate at which data flows in from sources such as business processes, application logs, networks, social media sites, sensors, mobile devices, and so on is referred to as Big Data Velocity. Data is constantly flowing in a massive amount.
  • Variability: This refers to the data’s inconsistency, which obstructs the process of effectively handling and managing the data.

Big Data can be classified as follows:

  • Structured: Structured data is any data that can be stored, accessed, and processed in a predetermined format. Numbers, dates, and strings of words and numbers are examples of structured data.
  • Unstructured: Unstructured data is defined as any data that has an unknown form or structure. Unstructured data, in addition to its enormous size, poses several processing challenges for extracting value. A heterogeneous data source containing a mix of simple text files, images, and videos is an example of unstructured data.
  • Semi-structured: Both types of data can be found in semi-structured data. Although semi-structured data appears to be structured in appearance, it is not. A data set represented in an XML file is an example of semi-structured data.

As a result of the increased productivity, they have been able to improve Customer Retention and increase sales. Modern Big Data tools assist Data Scientists and analysts in efficiently analyzing large amounts of data and providing a quick overview of more information. This improves their productivity as well.
  • Improved Customer Service: Any company’s marketing efforts must include improving customer interactions. Because Big Data analytics gives companies more information, they can use it to create more targeted marketing campaigns and unique, highly personalized offers for each client. Social media, email transactions, customer CRM (Customer Relationship Management) systems, and other sources of Big Data are among the most important. As a result, it provides businesses with a wealth of data on their customers’ pain points, touchpoints, values, and trends, allowing them to better serve them. Big Data also allows businesses to better understand their customers’ thoughts and feelings, allowing them to provide more personalized products and services. Customer satisfaction, relationships, and, most importantly, loyalty can all be improved by providing a personalized experience.
  • Increased Agility: Big Data also improves business agility, which is a competitive advantage. Big Data analytics can assist businesses in becoming more market disruptors and agile. Companies can gain insights ahead of their competitors by analyzing large data sets related to customers, allowing them to address customer pain points more efficiently and effectively.

To extract value from data, Data Science combines multiple fields such as Statistics, Scientific Methods, Artificial Intelligence (AI), and Data Analysis. Data scientists are individuals who use a variety of skills to analyze data collected from the web, smartphones, customers, sensors, and other sources to derive actionable insights.

Data Science refers to the process of cleansing, aggregating, and manipulating data to perform advanced data analysis. The results can then be reviewed by analytic applications and data scientists to uncover patterns and enable business leaders to make informed decisions.

The Data Science lifecycle is divided into five stages, each with its own set of responsibilities:

  • Capture: Data collection, data entry, signal reception, and data extraction are all steps in the data collection process. This stage entails gathering unstructured and structured data in its raw form.
  • Maintain: Data Warehousing, Data Cleansing, Data Staging, Data Processing, and Data Architecture are all terms that can be used to describe the processes that are used to prepare data. This stage entails converting raw data into a usable form.
  • Process: Data Mining, Clustering/Classification, Data Modeling, and Data Summarization are the steps involved in the process. Data scientists examine the prepared data for patterns, ranges, and biases to see if it can be used in predictive analysis.
  • Analyze: Exploratory/Confirmatory, Predictive Analysis, Regression, Text Mining, and Qualitative Analysis are some of the methods that can be used to analyze data. This is where the lifecycle gets going. This stage entails conducting various data analyses.
  • Communicate: Data Reporting, Data Visualization, Business Intelligence, and Decision-Making are all concepts that should be explained. Analysts prepare the analyses in easily readable forms such as charts, graphs, and reports in the final step.
