# Database Design Project
## Overview
This project involves designing a database system for a company that provides services to bus companies. The system covers two main services:
1. **Driver Outsourcing** - Managing the assignment and tracking of outsourced drivers.
2. **Trip, Maintenance, and Ticket Management** - Recording bus trips, maintenance activities, and ticket sales.
The project is structured into three essential stages:
1. **Conceptual Model** - High-level representation using ER diagrams.
2. **Logical Model** - Translating the conceptual model into a relational schema.
3. **Physical Model** - Implementing the database using SQL.
## Project Structure
- `/conceptual-model/` - Contains ER diagrams and documentation.
- `/logical-model/` - Includes relational schemas and normalization process.
- `/physical-model/` - SQL scripts for database creation and sample data.
## Steps
### 1. Conceptual Model
- Define entities, attributes, and relationships.
- Create an Entity-Relationship (ER) diagram.
### 2. Logical Model
- Convert the ER diagram into a relational schema.
- Normalize tables to reduce redundancy and improve integrity.
### 3. Physical Model
- Write SQL scripts to create tables, constraints, and indexes.
- Insert sample data for testing.
## Technologies Used
- **Diagram Tools**: [EERCASE](https://sites.google.com/a/cin.ufpe.br/eercase)
- **SQL**: DDL (Data Definition Language), DML (Data Manipulation Language)
## Getting Started
1. Clone this repository:
```sh
git clone https://github.com/Shellyda/project-design-database.git
```
2. Navigate to the project directory:
```sh
cd project-design-database
```
3. Execute theses SQL scripts in your preferred DBMS:
**Create database:**
```sh
psql -U user -d database -f physical-model/create_database.sql
```
**Populate database:**
```sh
psql -U user -d database -f physical-model/populate_database.sql
```
