+### SQL Basics
+Not technically a programming language
+Language used for interacting with relational database management systems
+
+SQL
+: structured query language
+
+There are different "flavors" SQL \
+Sometimes different depending on the management system
+
+#### 4 aspects
+Data Query language (DQL)
+: used to get data already stored
+
+Data definition language (DDL)
+: define layout, schema
+
+Data control language (DCL)
+: used for controlling access to the data in the database
+
+Data manipulation language (DML)
+: used for inserting, updating, deleting data from the databases
+
+#### Queries
+Goal is to only get the data you need \
+Often hidden in a complex schema
