Didnodb - A Simple NoSQL Database

Didnodb is a lightweight NoSQL database implemented in Python using FastAPI. It provides user authentication, data storage, and basic CRUD operations without requiring a traditional database management system.

Features

• User authentication (register, login, logout)
• Store and retrieve structured JSON data
• Session-based authentication
• Data indexing for faster retrieval
• Basic metrics for tracking users and stored data
