Data science according to Wikipedia is defined as
"Data science is an inter-disciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from many structural and unstructured data. Data science is related to data mining, machine learning and big data."
Many people have this notion that Data Science just means training Machine Learning models but it is an amalgamation of various fields. A person must have knowledge of statistics, cloud technologies, coding and databases to become a data scientist. With the increasing change in technology knowledge of DevOps for Machine Learning(known as MLOps) and AutoML is also necessary.
Kaggle the largest community of Data Scientists conducted a survey and based on that survey I am presenting the list of different tools and technologies widely used in different domains of Data Science. Feel free to add some other tools you know which are popular and not mentioned in this list.
Machine Learning Frameworks
Machine Learning is one of the core technologies associated with Data Science. Python and R are the widely used languages for ML. The most popular frameworks are based on Python namely scikit-learn, Tensorflow and PyTorch.
