What is meant by Data Science?
When processing raw, structured, and unstructured data utilizing various technologies, algorithms, and the scientific method, data science is a detailed study of the enormous quantity of available data.
It is an interdisciplinary area that manipulates data using tools and strategies to discover something fresh and significant.
Data science employs the most advanced technology, coding languages, and algorithms to address data-related issues. It is the secret to artificial intelligence's future.
We can sum up what data science is all about as follows:
- Using the right questions and basic data analysis.
- Analysing the data using a variety of smart and effective algorithms.
- Making use of data visualization for better comprehension.
- Understanding the facts can help you identify the answer and make better decisions.
Consider the scenario where you wish to drive from station A to station B. Now you need to make some choices, such as which one route will be the fastest to get to the destination, which route will have the least traffic, and which route will be the least expensive. We will utilize these decision-making criteria as input data to help us decide what action to take next. Therefore, this analysis of data is known as data analysis and is a component of data science.
Benefits of data science course
Data was scarcer and generally available in the organized form a few years ago, making it simple to store it in Excel sheets and analyze it with BI tools.
Every company needs data to operate, expand, and enhance its companies. However, in today's world, data is getting so vast that it is creating at the rate of 2.5 quintals of bytes each day, which has caused a data explosion. According to studies, by 2020, one individual will produce 1.7 MB of data every second.
Managing such a big amount of data is challenging for any company. Therefore, we needed smart, strong, and efficient algorithms and technologies to handle, process, and analyze information. The term "data science" refers to this technique. The use of data science technology is primarily motivated by the reasons listed below:
- With data science technology, we can transform enormous volumes of unstructured raw data into insightful knowledge.
- Many enterprises choose data science technologies, whether large corporations or new businesses. Companies that manage huge amounts of data, such as Google, Amazon, Netflix, and others, utilize data science techniques to enhance the customer experience.
- Data science aims to automate transportation, including the development of self-driving cars, which are the future wave.
- Data science may assist with various forecasts related to surveys, elections, confirming aircraft tickets, etc.
How will we get a job after this course?
Professionals who understand and analyze data using various statistical tools and machine-learning approaches are data scientists. According to several polls, the profession of a data scientist is becoming the most difficult in the twenty-first century. It has also been referred to as "the trendiest job title of the 21st century" by certain people.
According to many surveys, 11.5 million new employees would have been created by 2026, with the average annual salary for a data scientist falling between $95,000 and $ 165,000.
What types of positions are offered in data science
If you are familiar with data science, you can find several interesting job opportunities in this field. The essential job roles are as follows:
- Data Scientist
- Data Analyst
- Machine learning expert
- Data Engineer
1. Data Scientist: Data scientists select which inquiries their group should make before figuring out how to utilize the collected data to address those inquiries. For study and prediction, they usually develop statistical models.
Required skills: Professional language skills in R, SAS, SQL, Python, Hive, Pig, Apache Spark, and MATLAB are prerequisites for becoming a data scientist. Data scientists must be skilled in mathematics, statistics, visualization, and communication.
2. Data Analyst: A data analyst performs data analysis, examines the data, and looks for connections, linkages, patterns, and other things. Ultimately, he creates visualization and data analysis reports to assist in making decisions and addressing problems.
Required skills: You need a solid foundation in mathematics, business intelligence, data mining, and fundamental statistics to succeed as a data analyst. Several application programs and tools, such as MATLAB, Python, SQL, Hive, Pig, Excel, SAS, R, JS, Spark, etc., must also be known to you.
3. Machine learning expert: A worker who specialises in developing programmes that can "learn" from or adapt to the data and make predictions is known as a machine learning specialist. Programming includes the topic of machine learning.
Required skills: Python, C++, R, Java, and Hadoop are some examples of computer programming languages. Additionally, you should be familiar with different methods, analytical problem-solving abilities, probability, and statistics.
4. Data engineers: Systems for large-scale data collection, storage, access, and analytics are designed, built, and optimized by data engineers. They offer data pipelines for use by data scientists, data-focused apps, and some other data users. Additionally, data engineers provide methods for data collection that are utilized in modeling, mining, acquisition, and verification.
Required skills: Data engineers must be skilled in Python, C/C++, Java, Perl, and other programming languages, SQL, MongoDB, Cassandra, HBase, Apache Spark, Hive, and MapReduce.
