Client-Server Database Application

Project Overview

This project is a multi-threaded client-server database application built in C, designed to efficiently handle data storage and retrieval operations over a network. The server handles multiple client connections concurrently using POSIX threads, allowing for scalable and responsive performance. Communication between the client and server is facilitated through TCP sockets, with support for both PUT and GET operations on a custom file-based database.

Features

• Multi-threaded Server: Handles concurrent client connections using POSIX threads.
• TCP Socket Communication: Ensures reliable data transmission between client and server.
• Custom File-Based Database: Supports efficient data storage and retrieval with robust error handling.
• Scalability: Designed to handle multiple clients simultaneously with responsive performance.
• Robust Error Handling: Ensures data integrity and provides informative feedback on operations.

Project Structure

• server.c: The main server-side application that manages client connections and handles PUT and GET requests.
• client.c: The client-side application that connects to the server and sends requests for data storage or retrieval.
• msg.h: Header file containing the message structure and constants used for communication between the client and server.
• Makefile: A makefile for compiling the server and client programs.

How to Run

1. Compile the Server and Client:

   make
   

2. Run the Server:

   ./server [port_number]
   

3. Run the Client:

   ./client [server_hostname] [port_number]
   

4. Interact with the Server:
   • The client will prompt you to choose between PUT, GET, or QUIT operations.
   • Follow the prompts to store or retrieve records from the server's database.

Example Usage

1. Start the server:

   ./server 8080
   

2. Start the client and connect to the server:

   ./client localhost 8080
   

3. Use the client interface to send PUT and GET requests to the server.
