Banco do Brasil - Dev Day

A hands-on technical session at Banco do Brasil focused on using MongoDB with Java, from basic CRUD operations to more advanced data processing with the Aggregation Framework.

In this session at Banco do Brasil, we explored how to use the official MongoDB Java Driver to perform CRUD operations and interact with MongoDB from Java applications.

We also covered the MongoDB Aggregation Framework, showing how developers can build pipelines to filter, $project, $sort, $group, and transform data directly inside the database using Java.

The session was focused on practical examples, helping Java developers understand how to move from basic database operations to more advanced data processing scenarios with MongoDB.
