This project is an implementation of a Relational Algebra interpreter in Python. The RA-Engine allows you to run relational algebra queries in the terminal, providing a convenient way to manipulate and query relational databases.
To use RA-Engine, ensure you have the PLY package installed. You can find the PLY package here.
-
Terminal-Based Execution: Run the RA-Engine from the command line with a simple command like
python3 RA.py company, where "company" is the folder containing your database. -
Example Database Included: Explore the functionality immediately with the provided example database folder. The project includes a sample dataset to help you get started.
-
Query Examples: A collection of seven example queries is included in a text file, demonstrating the syntax and capabilities of the RA-Engine. Simply run
python3 RA.py companyfollowed by the queries to see the results.
- Clone the repository.
- Navigate to the project directory in your terminal.
- Run the RA-Engine with the command
python3 RA.py <your-database-folder>. - After RA: enter your query to search in your database.
Note: This project was created as part of a csc1302 honors lab, making it an excellent resource for students learning about relational databases and algebra.
