When learning data science, students typically focus on Python or R for data analysis and machine learning. On the job though, data is usually stored in a database, and that data can either be accessed through a business intelligence tool or directly using SQL.
This crash course is intended for beginners with no prior experience in SQL. By the end of the session, you will know:- what a database is and the difference between SQL and NoSQL
- what an RDBMS is and the difference between MySQL, Oracle, PostgreSQL, SQL Server, and SQLite
- how to see what’s in a database by looking at a data model
- how to find data in a database by writing a SQL query
- how to use SQL along with Python, R, Excel, etc.
