Storing Flexible Data for AI Assistants with MongoDB

Discover how MongoDB handles unstructured data like logs and activity records in AI applications.

MongoDB is a document-oriented NoSQL database designed for storing and querying flexible, unstructured data. In our AI assistant project, MongoDB can be used to store logs, user activity records, analytics data, and any content where the structure might change over time. Unlike traditional relational databases like Postgres, MongoDB stores data in JSON-like documents (called BSON) instead of tables and rows, which makes it easier to handle data with varying fields and nested structures.

Here’s how it works: when you store data in MongoDB, it’s organized into collections, each containing multiple documents. Each document can have its own fields and structures, making it highly adaptable. This is particularly useful for AI projects where the types of data — like conversation logs or model outputs — might not always fit into rigid table schemas. When you query MongoDB, it retrieves matching documents based on flexible filter criteria.
We use MongoDB because it offers horizontal scalability, meaning it can handle large datasets by distributing them across multiple servers (sharding). It’s also schema-less, which…
