Non-Relational Database

Types

• Key-Value Store
• Graph Store
• Column Store
• Document Store

Operations

• Join operations are generally not supported in non-relational databases.

Choice Structure

• Non-relational databases might be the right choice if:
  • Your application requires super-low latency.
  • Your data are unstructured, or you do not have any relational data.
  • You only need to serialize and deserialize data (JSON, XML, YAML, etc.).
  • You need to store a massive amount of data.
