Simple NoSQL Database in Python3

Welcome to the Simple NoSQL Database project! This project demonstrates the creation of a lightweight NoSQL database system built in Python 3, designed for learning and exploration.

Features

• Data Storage with Python Dictionaries: Tables and their data are stored using Python's dictionary data structures.
• Classmethods for Data Structure Operations: The project employs @classmethod for performing table and record manipulations in a modular and reusable manner.
• Regular Expressions for Parsing: Leverages Python's re module to locate and validate table names, column names, and other patterns.
• Error Handling: Implements robust error handling to ensure user-friendly feedback for invalid operations and data issues.

Use Cases

This project is a simple yet powerful learning tool that demonstrates key concepts of:

• Object-Oriented Programming (OOP)
• Basic data structure manipulation
• Regular expression parsing
• Error handling practices

Installation

1. Clone the repository:

   git clone https://github.com/Ramarajusairajesh/Database
   cd Database

2. Ensure you have Python 3 installed on your system.
3. Run the script directly using:

   python3 no_sql.py

Usage

Sample Commands

1. Create a Table:

   create table <TABLE_NAME> (<COLUMN_NAME> <TYPE>..)

   Creates a new table named users with columns id, name, and email.

2. Insert Data:

   insert into <TABLE_NAME> values(<VALUE1>...)

   Inserts a record into the users table.

3. Retrieve Data:

   select * from TABLE_NAME

   Returns all records from the users table.

4. Handle Errors Gracefully:

   • Attempting to create a duplicate table or access a non-existent table will raise meaningful exceptions.

Happy coding! Feel free to experiment and extend this project to suit your learning or development needs.
