Customer Scenarios

1. MongoDB is used for logging on application servers due to its flexible querying capabilities compared to plain text and the convenience of exporting data. This use also serves as a practical entry point for MongoDB, integrating it from peripheral systems.

2. MongoDB’s schema-less structure provides flexibility for storing third-party data in various formats, eliminating the need to create a unified format for each data source. This reduces development effort significantly.

3. MongoDB is highly convenient for developers due to its schema flexibility, allowing fields to be added without altering the table structure, and it has a very low learning curve.

4. MongoDB is used to store data on delivery drivers and merchants (including location data) for an O2O delivery app. MongoDB’s geospatial queries make it easy to locate nearby merchants and delivery drivers, enhancing search efficiency.
