Data Science vs. Big Data


Big data and data science are significant fields and principles that are becoming increasingly relevant. At no time in the past has the world collected or processed as much data as it does today, and at such a rapid pace. Furthermore, the variety and volume of the data are also rapidly increasing.

What is data science?

Data science is a broad term that covers many different disciplines and techniques, but in general, it refers to all the methods used for extracting information and knowledge from data. Many fields, including social media, medicine, health care, social sciences, biological sciences, engineering, economics, finance, marketing, and others, benefit from data science. Data science is an evolutionary branch of statistics that employs computer science techniques to manage massive datasets. Thus, it combines the disciplines of computer science, business, and statistics.

What is Big data?

Big Data is an application of data science wherein the data sets are quite large, and handling them requires overcoming logistical challenges. It is the voluminous data, information, or important statistics acquired by vast organizations and enterprises. The primary objective is collecting, extracting, storing, processing, and analyzing information from these voluminous data sets effectively. However, physical as well as computational constraints can make processing, as well as analysis of large massive data sets, difficult or impossible. As a result, specialized approaches and tools such as software, algorithms, parallel programming, and so on are necessary.

Big Data is used to incorporate these massive data sets, specialized approaches, and structured tools. It’s frequently applied to huge data sets to perform general data analysis and discover trends and build a predictive model. Big data is used to identify patterns and trends and influence judgments in relation to human behavior and interaction technology.

Data Science vs.Big Data

In reference to Big Data vs. Data Science, there are some significant contrasts that we should explore:

Organizations employ big data to improve efficiency, comprehend untapped markets, and boost competitiveness. In contrast, data science is concentrated on offering modelling techniques and procedures to accurately assess large data’s potential.

Companies can collect huge volumes of data, and it is certainly associated with big data, but data science is required to extract usable information from the data.

Data science is involved in making business decisions, while big data is more focused on technology, computer tools, and software.

Big data can easily improve performance. However, extracting insight from big data to maximize its potential for improving performance is a major concern. Apart from deductive and inductive reasoning, data science also employs theoretical and experimental methodologies. As a result, it can uncover all concealed insightful information from a complex mesh of unstructured data, enabling enterprises to maximize the potential of the enormous data.

Big data is generally defined by its variety, volume, and velocity (often regarded as the 3Vs), whereas data science refers to the methodologies or procedures used to evaluate data outlined by the 3Vs.

Big data analysis carries out the mining of meaningful information from massive amounts of data. In contrast to analysis, data science uses machine learning algorithms and statistical methodologies to teach a computer to learn without the need for extensive programming to make anticipations from big amounts of data. As a result, data science and big data analytics should not be confused as they are very different from each other.

Skills needed for becoming a Big Data Specialist

  • Data visualization and analytical abilities are required to look at significant patterns and solve problems from huge amounts of data.
  • Understanding of database development and management as well as necessary programming skills in languages like R.
  • Having imperative business skills such as understanding business objectives and communicating effectively.
  • Lastly, having a data certification is an additional benefit. To be successful, consider taking an online course.

Skills needed for becoming a Data Scientist

  • Data scientists are experts in data management and have strong analytical capabilities.
  • The majority of data scientists possess a Ph.D. or a master’s degree and strong programming skills, knowledge of statistics, and math capabilities.
  • Proficiency in Python, C/C++, R, Pearl, SAS, and Java languages.
  • Knowledge of Hadoop platforms and database systems is essential.
  • Business skills like efficient communication and industry knowledge.
  • Obtaining a certificate from a reputable institution.

Many high-ranking institutions offer quality data science training in Bangalore, Jaipur, Hyderabad, Gurgaon, Pune, and other cities.
