## Overview

This is a MySQL telephone-directory database project. The documented workflow is to add and maintain contacts, then retrieve them through listing, name search, and alphabetical sorting; users can also count contacts and view summaries. The README documents CRUD operations, stored procedures, and a summary view, but no SQL source excerpts were provided, so the graph shows only documented relationships and does not infer procedure-to-operation calls. All database components point to the sole SQL file in the tree.

Main entry points: [`database.sql`](https://github.com/uzaam07/telephone-directory-management-system/blob/main/database.sql) (Contacts table)
