AWS S3 is a key-value store, one of the major categories of NoSQL databases used for accumulating voluminous, mutating, unstructured, or semistructured data. Uploaded objects are referenced by a unique key, which can be any string. This high-level and generic storage structure affords users near-infinite flexibility.
Is S3 a SQL database?

Is MongoDB better than AWS?
MongoDB and DynamoDB are both solid NoSQL databases to support various user needs. However, careful consideration is required when selecting the best option. In an AWS world, it’s a no-brainer to go with the AWS native NoSQL solution if all the required features and functionality are available in DynamoDB.
Why is there NoSQL database?
NoSQL databases store data in a single data format, including a JSON document, rather than the traditional table structure of a relational database. Because this non-relational database architecture doesn’t really need a structure, it can quickly handle massive, often unorganized data sets.
What is the difference between SQL and NoSQL?
SQL is the programming language used to interface with relational databases. (Relational databases model data as records in rows and tables with logical links between them). NoSQL is a class of DBMs that are non-relational and generally do not use SQL.

Does Facebook use NoSQL?
NoSQL database systems are distributed, non-relational databases that also use non-SQL language and mechanisms in working with data. NoSQL databases can be found in companies like Amazon, Google, Netflix, and Facebook that are dependent on large volumes of data not suited to relational databases.
What SQL Cannot do?
If we consider queries in relational algebra which cannot be expressed as SQL queries then there are at least two things SQL cannot do. SQL has no equivalent of the DEE and DUM relations and cannot return those results from any query. Projection over the empty set of attributes is therefore impossible.
