How to encapsulate MongoDB operations in Go?

To encapsulate MongoDB operations in Go, you can use an Object-Relational Mapping (ORM) library likemgo. ORM libraries provide a higher-level abstraction over the MongoDB API, making it easier to work with MongoDB databases in Go.mgo. ORM libraries provide a higher-level abstraction over the MongoDB API, making it easier to work with MongoDB databases in Go.

What are the benefits of using an ORM like Mgo for MongoDB in Go?

Using an ORM likemgofor MongoDB in Go offers several benefits, including:

• Simplified API:ORMs provide a more user-friendly API for interacting with MongoDB, making it easier to perform common operations like querying, inserting, and updating data.
• Reduced Boilerplate Code:ORMs automatically generate much of the boilerplate code that would otherwise be required to work with MongoDB, reducing development time.
• Data Validation:ORMs can be used to enforce data validation rules, ensuring that data stored in the database is valid.

Can you provide an example of how to use a Go library to connect to and query a MongoDB database?
