What tools and methods have you used to interact with non-relational databases in your projects?

In projects involving interaction with NoSQL databases, I used various tools and methods depending on the specific DBMS:

• MongoDB: used official drivers (e.g., MongoDB.Driver for C# or Mongoose for Node.js) for CRUD operations, aggregations, indexing.
• Redis: employed client libraries for key-value operations, caching, and queues.
• Elasticsearch: interacted via REST API or client libraries for full-text search and analytics.

I also used tools for automating testing and data validation, such as writing queries, schema validation, and performance testing.

Overall, the approach depends on the type of database, but generally includes:

• using official or popular client libraries;
• constructing queries in a format supported by the database (JSON, DSL);
• processing results and errors;
• configuring indexes and optimizing queries.
