Demand for data science jobs is increasing day by day. Most companies in the world are looking for employees who have a piece of great knowledge of data science. In this tutorial, let us discuss each and every component of data science.
Data science mainly consists of 7 components. Statistics, domain expertise, data engineering, visualization, advanced computing, mathematics, and machine learning are the main data science components.
Statistics is the main and most important component of data science. As we all know data science is the process of taking useful insights from the data which are collected from different sources. These useful insights are used by data scientists to improve the business of a particular company.
In order to explore data statistical features are used by the data scientists. Statistical features mainly include data organizing which is mainly done to find out the minimum as well as maximum values, it is also used to find out the mean, mode, median values, and many more.
Some data consists of numerical data, collecting and analyzing numerical data is also very important. Statistics is a kind of tool or a way that is mainly used by each and every data scientist in order to collect as well as analyze a large amount of numerical data. Once the collection and analysis of numerical data are done then the useful insights are extracted from the data. Computer algorithms as well as some statistical formulas are used by the data scientists in order to dig out the useful insights from the raw data that is collected from multiple sources.
Domain Expertise is one of the other important components of data science. Domain expertise is a component that will mainly help for binding the data science together.
Domain expertise is defined as the deep core knowledge in a particular field or in a particular area. It will also play a very important role in decision-making and always binds the data together. Domain experts are very must required in various areas for improvement as well as take appropriate decisions in data science.
A domain expert will always help to identify the best data from the available sources and they will also be able to analyze how good a data is for use. All these are done very easily by them because of their deep knowledge as well as their experience in a particular field.
Data engineering is the process of acquiring, storing, retrieving, and data transforming. It includes metadata which means data about data.
Data is increasing day by day from different sources. A vast amount of data is produced each and every second whereas data engineering mainly deals with a large amount of data with the tools which is developed on their own. The main aim is to provide software solutions for the problems which are related to data.
The solution for the problems which are related to data is generated simply by creating a data pipeline and endpoints that are done within the system itself. Proper understanding of data technologies and frameworks are the main requirements which are needed for data science engineering. These are combined and used in order to create proper solutions which will surely enable the business processes.
Visualization is the process of representing data in a visual context. While we are representing the data in a visual context it will make or help the people to understand the significance of data very clearly.
As we all know visualization is the process of representing data where the data representation is done using common graphs such as plots, charts, animations, etc. When data scientists use these types of graphs for visualization it will make the common people understand the complex data and their relationships very easily.
Advanced computing is nothing but an extended version of data science. It is the technology that mainly deals with designing as well as developing computing hardware and software. Advanced computing also defines a PC which is high end and different types of skills which is used on the PCs. Word processing, graphics as well as multimedia, spreadsheets, databases, computers, etc are the skills of advanced computing.
In order to find a solution for a particular problem data scientists who works under a particular company have to build many predictive models and these predictive models are based on very hard maths. So a core knowledge of mathematics is very necessary for a data scientist.
Data scientists, data analysts, and many more employees who work for the company will use their technical knowledge, mathematical skills, and coding skills in order to solve as well as to extract useful insights from data that is obtained from multiple sources. To become a good data scientist should have great knowledge of mathematics. The study of quantity, the structure, and the occurring changes in business are the main things involved in mathematics.
Machine learning is another component of data science. Do you know which is the backbone of data science? The answer to this question is very clear, the backbone of data science is machine learning. So what do you mean by machine learning? Machine learning is nothing but it is a process of providing training to the computers in order to make them act as human brains.
To solve business problems various machine learning algorithms are used in data science. Regression and supervised clustering are some of the techniques which are used in machine learning to solve problems. In order to identify the business trends and patterns, machine learning algorithms are used. For predicting the qualities machine learning plays an important role. Some important algorithms which are used in machine learning are linear regression algorithm, k means clustering, decision tree, etc
Statistics, domain expertise, data engineering, advanced computing, visualization, mathematics, and machine learning are the important components of data science. All these components are equally important in data science in order to improve the business by extracting useful insights and patters as well trends from the collected data.
