## Overview

This is a Flask customer and contact-note management application backed by PostgreSQL. Users can create and maintain customer records, search active customers, record dated contact notes, and view a customer’s notes. The main workflow runs through Flask routes in `app.py`, which query or update PostgreSQL and render templates. A separate schema-initialization route creates the customer and contact tables and inserts sample rows. Database helper and setup implementations are sampled; template internals and container wiring are not, so those relationships are not expanded.

Main entry points: [`app.py`](https://github.com/padeghdev/ct519dockercompose/blob/main/app.py) (Flask routes), [`app/connectdb.py`](https://github.com/padeghdev/ct519dockercompose/blob/main/app/connectdb.py) (Connection helper), [`templates`](https://github.com/padeghdev/ct519dockercompose/tree/main/templates) (Contact pages), [`app/createtable_customer.py`](https://github.com/padeghdev/ct519dockercompose/blob/main/app/createtable_customer.py) (Customer table setup)
