## Notes - Key-value database, or key-value store, is a data storage paradigm that allows you to store opaque data collection with an associated key. - You restore the records by their keys. - Each key uniquely identifies a record. - Each collection may have different fields. - It works differently from relational databases (RDB) because RDBs predefine the data structure in the database as a series of tables containing well-defined data types. - It offers flexibility because you can store any object structure. - It uses less memory to store the same database compared with RDB. - Examples of key-value databases: - [DynamoDB](https://aws.amazon.com/dynamodb/). - [Redis](https://redis.io/). ## References - [Wikipedia.
