Flight Management System ✈️

University of Minho - Laboratórios de Informática III (2025/2026)

Grade: 20/20

📋 Project Overview

This project is a comprehensive C-based system developed to manage and analyze large datasets of flight information (Flights, Airports, Passengers, and Reservations). The application parses CSV data, validates integrity, and provides a high-performance query engine to extract statistics.

The development focuses on strict Modularity and Encapsulation, utilizing opaque pointers and separating interface from implementation.

Key Features

Data Parsing: robust handling of CSV files with syntactic and logical validation. Error Logging: Invalid records are automatically filtered and logged to specific error files (e.g., flights_errors.csv). 3 Execution Modes: Batch processing, Interactive Terminal UI, and Automated Testing. Performance: Optimized data structures (Hash Tables/Trees) to handle large volumes of data.

🛠️ Installation & Dependencies

Prerequisites

To compile and run this project, you need a Linux environment with the following dependencies installed:

• Compiler: gcc
• Build System: make
• Libraries:
  • glib2.0 (for generic data structures)
  • ncurses, readline, history (for the Interactive Mode UI)

Install dependencies (Ubuntu/Debian):

sudo apt install gcc make libglib2.0-dev libncurses-dev libreadline-dev

• programa-principal: Batch processing engine.
• programa-interativo: Terminal-based user interface.
• programa-testes: Automated testing and benchmarking tool.

💻 Usage & Execution Modes

The application supports three distinct modes of execution.

1. Batch Mode (Principal)

This is the main processing engine used by the automatic evaluation platform. [cite_start]It accepts a dataset directory and a file containing a list of commands [cite: 209-211].

Syntax:

./programa-principal <dataset_path> <input_file>

Interactive Mode

A user-friendly terminal interface that allows users to explore the data dynamically. Syntax:

./programa-interativo

Features:

Prompts for the dataset path upon launch.

Menu-driven query selection.

Paginated output for large results.

Interface Previews:

Main Menu Select queries and load datasets easily via the text-based UI.

Query Results View formatted results directly in your terminal.

Test Mode

This mode is used to validate the correctness of the implementation and measure performance (time and memory). It compares the program's output against a set of expected results .

Syntax:

./programa-testes <dataset_path> <input_file> <expected_output_dir>
