Navicat for MongoDB gives you a highly effective GUI interface for MongoDB database management, administration and development.
Starting in MongoDB 8.0, you can configure the Database Profiler to log slow operations based on the time that MongoDB spends working on that operation, rather than the total latency for the operation. This means that factors such as waiting for locks and flow control do not affect whether ...

“Navicat does an excellent job and as an added bonus, we can use the export function to convert data into other formats for specialized use. The XML conversion was particularly impressive.” Donald J. Varney Systems Developer III State of Vermont - Department of Banking, ...
Next, it's crucial to appropriately format the dataset and its contents for MongoDB ingestion. In the upcoming steps, we'll transform the current structure of the dataset, dataset_df— presently a DataFrame object — into a JSON string. This dataset conversion is done in the line documents ...

JSONcan only directly represent a subset of the types supported byBSON. To preserve type information, MongoDB adds the following extensions to the JSON format. Canonical Mode A string format that emphasizes type preservation at the expense of readability and interoperability. That is, conversion from...

For most data types, however, comparison operators only perform comparisons on documents where the BSON type of the target field matches the type of the query operan...
