DbSchema - Diagrams and Relational Data Browse for MongoDB

<a href="http://www.dbschema.com">DbSchema</a> is a visual designer for MongoDb, capable to represent the database structure by scanning the data and deducing a logical 'schema'.
In this way you get a structural description and a visual representation of the database.
The schema and diagrams will be saved to project file in XML format. The project file can be shared in a team using versioning systems.

Relational Data Browse, a module inside DbSchema, allows to explore and edit data from the database.
If a collection is referring data from other collection using unique identifiers, you may set virtual relations between collections ( a kind of virtual foreign keys ).
In Relational Data Browse this will allow to simultaneously explore the data from both collections and view the matching records.
The browse editor will be saved to project file, allowing to get a persistant views over the data.

Native visual query builder, query editor and random data generator are available.
