+#### What is a Database (DB)?
+- a collection of related information
+- databases can be stored in different ways
+
+Computers + Databases = <3
+: computers are great at keeping track of large amounts of information
 
+Database management Systems (DBMS)
+: a special software program that helps users create and maintain a database
+* makes it easy to manage large amounts of information
+* handles security, backups, imports/exports, concurrency[^1]
+* interact with software applications, ex: programming languages

+#### Two types of Databases
+* **Relational databases (SQL)**
     * organize data into one or more tables
     * a unique key identifies each row
-* Non-Relational databases (noSQL)
+* **Non-Relational databases (noSQL)**
     * organize data in anything but a table
