## Overview

Data-Manager is a command-line review manager. Consumers can create reviews or look up existing ones; staff authenticate with a code, find a review, and optionally alter it. The single script handles these branches, displays review data, and reads or writes newline-delimited JSON in database.txt. The implementation is small and concentrated in main.py; the graph separates its user-facing workflows for clarity. Evidence is limited to the README and the excerpted main.py.

Main entry points: [`main.py`](https://github.com/mrmaker53/data-manager/blob/main/main.py) (Review CLI), [`database.txt`](https://github.com/mrmaker53/data-manager/blob/main/database.txt) (Review Database)
