JSON Database Client-Server Application

Overview

This project is a JSON database client-server application. It operates as a client-server architecture, allowing multiple clients to interact with a central server. The database is stored in a JSON file located at /resources/db.json.

Features

• Data Operations: Supports three primary operations:

  • Set: Add or update data in the database.
  • Get: Retrieve data from the database.
  • Delete: Remove data from the database.

• Nested Entries: Supports nested data structures, allowing for complex data organization and retrieval.

• Command-Line Interface: The client interacts with the server via command-line arguments for straightforward usage.

• File Input Support: Commands can be read from a file using the -in argument for batch processing.

• Multithreading Support: The server is capable of handling multiple client connections simultaneously.

• Command Design Pattern: Implements the command design pattern for executing commands, enhancing maintainability and scalability.

Using the Client

To interact with the server, use the client CLI. The following command-line arguments are supported:

• -t (type): Specify the operation type (set, get, or delete).
• -k (index): Provide the database index/key for the operation.
• -v (value): Provide the value for set operations.
• -in: Specify a file containing commands to execute.

Examples

Set a Value

To set a value in the database, use the following arguments:

-t set -k name -v "John Doe"

Get a value

To retrieve the value of a specific key:

-t get -k name

Delete a value

To delete a key-value pair from the database:

-t delete -k name
