Your data comes in JSON-like documents, key-value pairs, graphs, or wide tables. You can tolerate some eventual consistency in exchange for availability and speed. When to be cautious ...

SQL Versus NoSQL: Choosing the Right Database Choosing a database is a core part of building software. SQL databases are relational systems. They use tables with defined schemas, and they enforce ACID transactions for consistency. NoSQL includes document stores, key-value stores, wide-column databases, and graph databases. They are usually schema-flexible and designed to scale out across many servers. This mix means you can pick a store that fits your data and your goals. ...
