Family Tree Warehouse Application (FTWA)

Marmara University CSE2260 - Principles of Programming Languages project. FTWA is a robust, object-oriented, command-line based application designed to construct and manage ancestral hierarchies.

🚀 Overview

FTWA allows users to build a family tree from scratch, manage genealogical data, and query complex kinship relationships. Unlike static databases, FTWA dynamically calculates relationships (e.g., aunt, cousin, brother-in-law) based on the current state of the tree and enforces strict biological and legal validation rules (e.g., age limits, consanguinity prohibitions).

🛠 Features

• Dynamic Hierarchy: Dynamically calculates generational levels and kinship ties.
• Smart Validation: Prevents biologically unrealistic scenarios (e.g., child born before parent's birth, unrealistic age gaps) and prohibits invalid marriages (incest/age restrictions).
• Kinship Queries: Supports a wide range of Turkish kinship terms including Amca, Hala, Dayı, Teyze, Bacanak, Elti, Kayınbirader, etc.
• Interactive CLI: A continuously prompting, user-friendly command-line interface.
• In-Memory Store: Efficient $O(1)$ data retrieval using dictionary-based indexing.

📋 Project Requirements

• Python 3.6 or higher.
• No external libraries required (Standard library only).

💻 How to Run

1. Clone the repository:

git clone https://github.com/yourusername/FTWA.git

2. Navigate to the project directory:

cd family_tree_warehouse_app

3. Run the application:

python Person.py

🏗 System Architecture

The core architecture is built upon an object-oriented Person class.

• Global Data: Maintained via a dictionary (family_tree) for high-performance mapping of Full Name -> Person Object.
• Recursive Logic: Uses recursive algorithms to traverse lineage, accurately calculate tree levels, and resolve complex kinship chains without infinite loops.
