Skill Required: Computer programming languages such as Python, C++, R, Java, and Hadoop. The machine learning expert is the one who works with various machine learning algorithms used in data science such as regression, clustering, classification, decision tree, random forest, etc. You should also be familiar with some computer languages and tools such as MATLAB, Python, SQL, Hive, Pig, Excel, SAS, R, JS, Spark, etc. Skill required: For becoming a data analyst, you must get a good background in mathematics, business intelligence, data mining, and basic knowledge of statistics. At the end of the day, he comes up with visualization and reporting for analyzing the data for decision making and problem-solving process. The main job roles are given below:īelow is the explanation of some critical job titles of data science.ĭata analyst is an individual, who performs mining of huge amount of data, models the data, looks for patterns, relationship, trends, and so on. If you learn data science, then you get the opportunity to find the various exciting job roles in this domain. The average salary range for data scientist will be approximately $95,000 to $ 165,000 per annum, and as per different researches, about 11.5 millions of job will be created by the year 2026. Data scientists are the experts who can use various statistical tools and machine learning algorithms to understand and analyze the data. Some people also called it 'the hottest job title of the 21st century'. Data science can help in different predictions such as various survey, elections, flight ticket confirmation, etc.Īs per various surveys, data scientist job is becoming the most demanding Job of the 21st century due to increasing demands for data science.Data science is working for automating transportation such as creating a self-driving car, which is the future of transportation.Google, Amazon, Netflix, etc, which handle the huge amount of data, are using data science algorithms for better customer experience. Data science technology is opting by various companies, whether it is a big brand or a startup.With the help of data science technology, we can convert the massive amount of raw and unstructured data into meaningful insights.Following are some main reasons for using data science technology: So to handle, process, and analysis of this, we required some complex, powerful, and efficient algorithms and technology, and that technology came into existence as data Science. Now, handling of such huge amount of data is a challenging task for every organization. Every Company requires data to work, grow, and improve their businesses. It is estimated as per researches, that by 2020, 1.7 MB of data will be created at every single second, by a single person on earth. Some years ago, data was less and mostly available in a structured form, which could be easily stored in excel sheets, and processed using BI tools.īut in today's world, data is becoming so vast, i.e., approximately 2.5 quintals bytes of data is generating on every day, which led to data explosion. All these decision factors will act as input data, and we will get an appropriate answer from these decisions, so this analysis of data is called the data analysis, which is a part of data science. Now, we need to take some decisions such as which route will be the best route to reach faster at the location, in which route there will be no traffic jam, and which will be cost-effective. Let suppose we want to travel from station A to station B by car. Understanding the data to make better decisions and finding the final result.Visualizing the data to get a better perspective.Modeling the data using various complex and efficient algorithms.Asking the correct questions and analyzing the raw data.In short, we can say that data science is all about: It is the future of artificial intelligence. It is a multidisciplinary field that uses tools and techniques to manipulate the data so that you can find something new and meaningful.ĭata science uses the most powerful hardware, programming systems, and most efficient algorithms to solve the data related problems. In this tutorial, we are giving an introduction to data science, with data science Job roles, tools for data science, components of data science, application, etc.ĭata science is a deep study of the massive amount of data, which involves extracting meaningful insights from raw, structured, and unstructured data that is processed using the scientific method, different technologies, and algorithms.

Every organization is looking for candidates with knowledge of data science. Next → Data Science Tutorial for Beginnersĭata Science has become the most demanding job of the 21st century.
