Computer science is a broad field studying the nature of computation, its implementation, and its application. Data analytics is such an application. Data science shares courses in computer science. They cover programming, databases, artificial intelligence programming, and mathematical writing. The shared concepts are in data structures, algorithms, and programming in a computer language. But data science includes less computer discipline and more statistical and mathematical work. You can get a hands-on project by referring to Data Science online courses which will teach you Data Science from scratch to advance.
If you are looking for a Data Science project then also check out the following video tutorial which is based on projects and you will learn how to implement a book recommender system end to end:
