Key-Value Database

A NoSQL key-value database implemented in C++. This project supports CRUD operations, persistence, and a simple query language.

Features

• CRUD Operations: Create, Read, Update, and Delete key-value pairs.
• Persistence: Save and load the database to and from disk.
• Query Language: A simple query language to interact with the database.
• Singleton Pattern: Ensures a single instance of the query language.
• Modular Design: Organized into separate classes for better maintainability.
