Comparison of Top Data Science Tools

There are some tools every data scientist should know. Python and R are the most popular when it comes to analysis and modeling, whereas Tableau and Power BI are more relevant in visualisation. Apache Spark is an outstanding choice when it comes to big data processing. On the other hand, TensorFlow is superior when it comes to deep learning applications. According to the latest data science tools and software trends, focus is more on cloud-native, automated machine learning (AutoML) and real-time processing. The tools used for data science are also getting more integrated, providing end-to-end solutions spanning the whole data science software pipeline. Data science tools for beginners include Python, SQL, and some visualisation tools such as Tableau or Power BI. These introductory skills will lay a good foundation to help you learn more sophisticated tools that are applied in data science.

Conclusion
