Hardcoded data, schema, and queries directory paths limit portability #7
Description
Problem
SalesTracker uses hardcoded paths for database, schema, and queries directories relative to the script location. This limits deployment flexibility (e.g., Docker, CI/CD, or alternative deployment structures), and environment variables are not considered.
Expected Behavior
Allow overriding these paths via environment variables or config file for better deployment portability.
Suggested Fix
- Refactor to allow dynamic directory configuration through environment variables or config file options.
