The schema, which is called the “active metadata” when it is being used by the driver, determines how the driver maps the data types.
If the driver is connected without providing a target schema map, the driver will generate an in-memory schema map during the connection process.
Should you encounter an issue where you encounter this in the form of a Java heap space error, you can launch Schema Editor by specifying larger initial and maximum values for the memory allocation pool as follows by using command line to open the Schema located in the Tools folder of the install directory: In some cases, the driver must cache data from tables locally before it can create the final result set.
This can occur when the driver needs to perform large, complex operations, such an ORDER BY, GROUP BY, DISTINCT or JOIN, on the client side.

If a database, table or column appears missing, check your sampling settings and resample.
For detailed instructions, see the full documentation located here.
To enable ODBC/JDBC applications to work with Mongo DB data, the Simba Mongo DB Driver maps Mongo DB data types to SQL data types.
The drawback of this is that sampling needs to occur on each connection.
You can also manually define a schema and store it to the database to shared with other users or save it to a local JSON file for personal use.
