Introduction to Data Science, Big Data and Data Analysis

Definition, Introduction, and Concepts

What is Data Science?

Data Science involves data preparation, data cleansing, and data analysis. It’s a tool to extract information and to deal with Big Data.

Data scientists compile the initially gathered data sets from separate disciplines such as mathematics, statistics, etc after which they apply predictive analysis, sentiment analysis, and machine learning and later sharpen the point more to derive something. The required useful information is finally extracted from it.

Data scientist provides right predictions and changes for the data by understanding it in a business view, thereby preventing future losses of a business person belonging to top data science programs.

What is Big Data?

Big Data definition as per Gartner is - high volume, high velocity, and high variety information data that require cost-effective, information processing innovation forms which enable process automation, enhanced insights and decision making.

Big Data database is the incredibly large volume of data that is difficult to process effectively by the existing traditional applicators.

Big Data processing starts with non-aggregated raw data which is not possible to be stored in a single computer. Big Data technology runs a business on a daily basis. Big Data systems are something that analyzes insights which leads to strategic business moves by taking better decisions.

Big Data in simple terms is a huge volume of data collection that keeps growing with time. It is so enoumous and complicated that no data management tool is able to process or store it efficiently.

What is Data Analytics?

Data Analytics is the process of finding a conclusion of information after an examination of its raw data. It includes the application of a mechanical process or an algorithm for the derivation of insights such as going through multiple data sets and searching for the relation between them.

Various organizations from different industries use data analytics basics for verification and disagreement on the existing models or theories. The focus of data analytics programs however lies in the process of coming to a conclusion on the basis of what is already known by the researchers.

Talking about data analytics definition - It is a technique of advanced analytics for diverse and enormous sets of data from different sources that can be structured, semi-structured and unstructured; in varied sizes up to terabytes and zettabytes.
