Database Querying with R and SQL

Connecting R to SQL databases is a critical skill for modern data professionals who need to work with datasets that are too large or secure to store in flat files. This course guides you through bridging the gap between database management and statistical programming, enabling you to extract, filter, and analyze database tables directly within your R environment. What you'll learn: - Understand foundational database concepts, relational schemas, and basic SQL query structures. - Connect R to local and remote databases securely using the DBI package and environment variables. - Query database tables using standard SQL syntax executed directly from R scripts. - Leverage modern tools like dbplyr to write clean R code that automatically translates into optimized SQL queries. - Import, filter, and aggregate large datasets efficiently before loading them into R's local memory. - Practice database integration workflows through structured written exercises and real-world scenario analysis. You will start with essential database terminology and connection protocols, progress to writing native SQL queries within R, and finish by exploring modern database-to-R pipelines. This course is designed for beginners who have a basic familiarity with R and want to learn database querying; no prior SQL or database administration experience is required. Start reading today to unlock the power of database querying directly within your R workflows.
