What is a database?
A database is an electronically stored, systematic collection of data. It can contain any type of data, including words, numbers, images, videos, and files. You can use software called a database management system (DBMS) to store, retrieve, and edit data. In computer systems, the word database can also refer to any DBMS, to the database system, or to an application associated with the database.

AWS Cloud Databases provides a broad selection of purpose-built databases for any enterprise. AWS databases support all database management tasks, such as server provisioning, patching, configuration, and backups. As a result, you can focus on application development while AWS continuously monitors your databases and automates scaling. The following are some examples of AWS database services:

Amazon Relational Database Service (Amazon RDS) is a managed service that makes it easy to set up, operate, and scale a relational database in the cloud.
Amazon Aurora is a relational database built for the cloud. As a fully managed service, it automates time-consuming tasks such as provisioning, patching, backup, recovery, failure detection, and repair.
Amazon Neptune is a graph-oriented database that can execute more than 100,000 queries per second.
Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud.
Amazon ElastiCache is an in-memory NoSQL database that is fully managed, scalable, and secure. It is a popular choice for mobile apps, gaming, e-commerce, and other applications where frequently accessed data must be stored in memory.
