🐘 COBOL + SQLite CRUD in Docker

This project demonstrates a full CRUD application in COBOL using SQLite, running inside a Docker container.
The COBOL program executes SQL commands through the SQLite CLI, showing how old-school COBOL can still work with modern databases.

---

🚀 Features

• Dockerized environment (Debian + GnuCOBOL + SQLite)
• SQL schema initialized with init.sql
• COBOL program performing Create, Read, Update, Delete (CRUD)
• No host dependencies (only Docker required)

🛠️ How to Run

1. Build and start the container

docker compose up -d --build

2. Enter the container

docker exec -it cobol-sqlite bash

3. Initialize the database

sqlite3 employees.db < init.sql

4. Compile the COBOL program

cobc -x crud.cbl -o crud

5. Run the program

./crud

🎯 Next Steps

• Replace SQLite with PostgreSQL or MySQL using ODBC.
• Wrap SQL calls in COBOL procedures for cleaner code.
• Extend with user input (interactive CRUD from terminal).
