5. Types of databases

• Databases have two main types we’re concerned with in this course, relational and non-relational

Relational Databases

• Get their name from their ability to link (or relate) different pieces of data together
• This is done through tables, where all data is stored in some form of table
• Then the database provides mechanisms to link those tables together

Non-relational Databases

• Also known as NoSQL databases
• Get their name for their ability to store data in a way that doesn’t require the rigid structure and relations of a relational database
• Originally designed with the cloud in mind, so they scale well across multiple servers
