Overview relational databases (such as sql server) are an excellent and efficient way to store large sets of data. structured query language (sql) is a programming language for interacting with these databases to add or edit tables, add or edit the rows of data within those tables, and merge or retrieve the data across multiple tables. Relational databases are a common way to store information, and sql is a widely used language for managing data held in these systems. rstudio provides several options to work with these crucial tools. Where possible, much of the data wrangling needed for generating analytic tables can be performed within the database, with results converted to data frames for statistical analysis or visualization within r. in this workshop, we will cover basic functionality of the r dbi package, which controls the basic communication between r and sql databases.
