# CustomeSQLDatabase
## Overview
This project is a prototype of a lightweight Database Management System (DBMS) implemented in Java. It provides a console-based interface for SQL query execution, features two-factor user authentication, and manages transactions with ACID properties. Data is stored persistently in a custom text format.
## Features
- **SQL Query Support**: Handles `CREATE`, `SELECT`, and `INSERT` SQL commands.
- **Two-Factor Authentication**: Implements user authentication with ID, password, and a CAPTCHA.
- **Transaction Management**: ACID-compliant transactions supporting `BEGIN TRANSACTION`, `COMMIT`, and `ROLLBACK`.
- **Persistent Storage**: Stores data in a custom text format with user-defined delimiters.
## Requirements
- Java Development Kit (JDK) - any version is acceptable
- Standard Java libraries (no third-party libraries used)
## Getting Started
1. **Clone the Repository**
```bash
git clone https://github.com/Keval-Gandevia/CustomSQLDatabase.git
```
2. **Navigate to the Project Directory**
```bash
cd CustomSQLDatabase
```
3. **Compile the Code**
```bash
javac -d bin src/*.java
```
4. **Compile the Code**
```bash
java -cp bin Main
```
## Usage
1. **Register**
Users must register first with their email, password, and CAPTCHA. Registration data is saved in an authentication file (.txt).
2. **Login**
Authenticate with your registered email, password, and CAPTCHA.
3. **Execute SQL Queries**
Enter SQL commands to create tables, insert data, and select records.
4. **Manage Transactions**
Use `BEGIN TRANSACTION`, `COMMIT`, and `ROLLBACK` commands to handle transactions.
