  What is DataScience? • Data Science is – “an informative science that extracts knowledge from various domains. That requires using many algorithms, methods, systems or techniques for scrapping this data and interpret it”. – related to data mining, machine learning, and big data. – Based on using statistics, analysis, or informatics, and their related methods. 3 Data_Science_lecture1_by_Doaa_Mohey
