# Database Project

This project implements a simple database system with a client-server architecture.

## Features

- TCP-based client-server communication

- Interactive command-line interface for the client

- Basic key-value store operations (GET, SET, UPDATE, DEL)

- B-tree index for efficient data storage and retrieval

## Project Structure

- `backend/`: Contains the database server implementation

- `database-client/`: Contains the client implementation

## Getting Started

1. Clone the repository

2. Run `cargo build` to compile the project

3. Start the server with `cargo run`

4. Run the client with `cargo run --bin client`

## Usage

Once connected to the database, you can use the following commands:

- `GET `: Retrieve the value associated with the given key

- `SET  `: Set a key-value pair (also supports operations like +, -, ...)

- `UPDATE  `: Update an existing key-value pair

- `DEL `: Delete a key-value pair

- `STRLEN `: Get the length of the value associated with the given key

- `STRCAT  `: Concatenate the values of two keys and store the result in a third key

- `SUBSTR   `: Get a substring of the value associated with the given key

- `exit`: Quit the client

- `help`: Display available commands

### Expression Examples:

- `EXPR(GET 1 + GET 2)`: Retrieve the value associated with key 1 and key 2, then add them together.

- `EXPR(GET 1 * 2)`: Retrieve the value associated with key 1 and multiply it by 2.

Use TAB for command completion in the client interface.

## Future Improvements

- Improve error handling and logging
