Data Science is a mixture of many scientific areas. As a beginner in the Data Science field and not good at memorizing all syntax and its roles, I frequently got trouble when switching between programming languages or areas. Many scientists have developed diverse types of cheat sheets to help people like me. However, I did not find any webpages that contain all the areas that I needed. Therefore, I have developed this webpage for that mission. Moreover, this is also a chance for me to review most of knowledge in data science field.
