The SQL (structured query language) programming language is often used to pull data from the various tables in a database and to assemble the data in a format amenable to statistical analysis or review.
The purpose of this course is to teach you how to extract data from a relational database using SQL so you can perform statistical operations. The focus is on structuring queries to extract structured data (not on building databases or methods of handling big data). This is an introductory course that will help you think “like” a relational database in order to manipulate matrices and vectors of data using SQL queries.
