It requires no external dependencies or server setup, making it ideal for small-scale projects, scripts, and prototypes. The library supports full CRUD operations (create, read, update, delete) through a Pythonic API, uses Python dictionaries as document structures, and allows schema-less storage where documents can have different fields. While easy to use for single-process applications, TinyDB lacks relational features, ACID guarantees, and multi-user support, limiting its use to local, small-dataset scenarios. ## Full article daily.dev links to this article rather than hosting it.
