Contact Management System

This project is a contact management system that stores, manages, and organizes contact information in multiple formats: SQLite, CSV, JSON, and a custom format called İsmetify. The system allows you to create, read, update, and delete contacts through a terminal-based menu system. The contact data is backed up automatically, and you can also restore it from previous backups.

Features

• Multiple Data Sources:

  • SQLite database (SQLData/mydatabase.db)
  • CSV file (CSVData/contacts.csv)
  • JSON file (JSONData/contacts.json)
  • İsmetify file (IsmetifyData/contacts.txt)

• CRUD Operations:

  • Add Contacts: Add a new contact to all formats.
  • List Contacts: Display all contacts stored in the SQLite database.
  • Edit Contacts: Edit contact information and update all formats.
  • Delete Contacts: Remove a contact from all formats.

• Backup and Restore:

  • Backup: Automatically backs up all data into a Backup folder.
  • Restore: Restore data from the Backup folder.

• Data Formats:

  • SQLite: Stores structured contact data in an SQLite database.
  • CSV: Stores contact data as a CSV file.
  • JSON: Stores contact data in JSON format.
  • İsmetify: Stores contact data in a custom plain text format where each entry is separated by a pipe (|).

File Structure

• SQLData/: Contains the SQLite database (mydatabase.db).
• CSVData/: Contains the CSV file (contacts.csv).
• JSONData/: Contains the JSON file (contacts.json).
• IsmetifyData/: Contains the custom İsmetify text file (contacts.txt).
• Backup/: Stores backup files for each format.

Setup

1. Clone the repository.
2. Install the required dependencies:

   pip install sqlite3 csv json os shutil simple_term_menu

3. Run the program:

   python main.py

Dependencies

The project relies on the following libraries:

• sqlite3: For handling SQLite database operations.
• csv: For handling CSV file operations.
• json: For handling JSON file operations.
• os: For managing directories and file paths.
• shutil: For file backup and restoration.
• simple_term_menu: For creating a simple terminal-based menu system.

Usage

When you run the program, you'll see a terminal-based menu with the following options:

1. Add Contact: Prompts you to input contact details and adds them to all formats.
2. Delete Contact: Removes a contact from all formats.
3. List Contacts: Displays all contacts from the SQLite database.
4. Edit Contact: Allows you to edit contact details and updates all formats.
5. Restore Backup: Restores contact data from the Backup folder.
6. Exit: Closes the program.

Backup and Restore

• Backup: Every time you add, edit, or delete a contact, the system automatically creates a backup of all data files in the Backup folder.
• Restore: You can restore the contact data from backups by selecting the "Restore Backup" option from the main menu.

Future Enhancements

• Add support for importing and exporting data.
• Implement sorting and filtering functionalities for contact listing.
• Add error handling for invalid inputs.
