Data Science And Its Growing Importance
An interdisciplinary field, data science deals with processes and systems, which are used to extract knowledge or insights from large amounts of data. The extracted data can be structured or unstructured. Data science is a continuation of data analysis fields, such as data mining, statistics, predictive analysis.
A vast field, data science uses many theories and techniques that are part of other fields such as information science, mathematics, most of the methods used in data science include probability models, machine learning, processing of signals, data mining, statistical learning, database, data engineering, visualization, recognition and learning that has become one of the most important in the history of science and information technology. a big field, because the Big Data solutions are more focused on the organization and the preprocessing of the data, in order to analyze the data.
Data Scientist
A data scientist is an individual, organization or application that performs statistical analysis, data mining and recovery processes in a large amount of data to identify trends, numbers and other relevant information. A data scientist performs data analysis on data stored in data warehouses or data centers to solve various business problems, optimize performance and gather business intelligence.

Types of Data Analytics
Descriptive analysis
The descriptive analysis describes what happened during a certain period of time. The number of visits has gone up? Are sales stronger this month than the last ones?
The diagnostic analysis
The diagnostic analysis focuses more on why something happened. This implies more diverse data entries and a little hypothesis. Did the weather affect beer sales? Did this most recent marketing campaign impact sales?
Predictive analysis
The predictive analysis moves to what is likely to happen in the short term. What happened to the sales of the last time we had a hot summer? How many climate models foresee a hot summer this year?
Prescriptive analysis
The prescriptive analysis suggests a course of action. If the probability of a hot summer is measured as an average of these five climate models is greater than 58%, we must add a night shift to the brewery and rent an additional tank to increase production.
