What is Amazon RDS?

Amazon RDS is AWS's relational database service. It's a fully managed relational database. There are many different types of databases. Very broadly speaking, database engines are either relational or non-relational. Of course, there are other types of databases, but they tend to be used for very specific use cases. Relational and non-relational databases are more commonly used for applications.
An example of a relational database would be MySQL, Postgres, or MariaDB. The most popular non-relational database is Mongo followed by Redis, though Redis is typically used for cache and not long-term data storage.
