## Overview

This is a small Flask product-catalog app. A user opens the catalog or search page, then can retrieve products (optionally by name) and add, update, or delete them through the product API; the API persists product records in SQLite. The templates are present, but their client-side behavior was not sampled, so no template-to-API wiring is asserted. The database relationship follows the ORM queries and session writes in `db.py`.

Main entry points: [`db.py`](https://github.com/tams-maker/product-inventory-system/blob/main/db.py) (Page routes), [`templates/index.html`](https://github.com/tams-maker/product-inventory-system/blob/main/templates/index.html) (Catalog page), [`templates/search.html`](https://github.com/tams-maker/product-inventory-system/blob/main/templates/search.html) (Search page), [`instance/products.db`](https://github.com/tams-maker/product-inventory-system/blob/main/instance/products.db) (Products SQLite)
