Name | MongoDB |
---|---|
Best used | If you need dynamic queries. If you prefer to define indexes, not map/reduce functions. If you need good performance on a big DB. If you wanted CouchDB, but your data changes too much, filling up disks. |
Usage example | For all things that you would do with MySQL or PostgreSQL, but having predefined columns really holds you back. |
Known Shortcomings | |
Main focus | Retains some friendly properties of SQL. (Query, index) |
License | AGPL (Drivers: Apache) |
Preisgestaltung | Free download or Pay per instance + Service (MongoLab) |
