Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

document database

A database that stores whole JSON-like documents instead of rows in tables.

A document database stores self-describing documents (BSON in MongoDB) grouped in collections, trading joins and fixed schemas for flexible, nested records.

Examples

  • One MongoDB order document with its lines inside it: { "_id": 42, "lines": [{ "sku": "MUG", "qty": 2 }] }.
