## Overview

This is a console-based university records manager. The user selects an entity and CRUD operation in the console; the application uses entity-specific DAOs to persist records in MySQL. The README documents the menu, five entity types, DAO separation, JDBC/MySQL storage, and database setup. No source excerpts were provided, so the graph reflects documented architecture only; specific method-level calls and data mappings are not inferred.

Main entry points: [`src/main/java/org/example/Main.java`](https://github.com/jaidmulla33-tech/universitymanagement/blob/main/src/main/java/org/example/Main.java) (Console menu), [`src/main/java/org/example/dao/DepartmentDAO.java`](https://github.com/jaidmulla33-tech/universitymanagement/blob/main/src/main/java/org/example/dao/DepartmentDAO.java) (Department DAO), [`src/main/java/org/example/dao/ProfessorDAO.java`](https://github.com/jaidmulla33-tech/universitymanagement/blob/main/src/main/java/org/example/dao/ProfessorDAO.java) (Professor DAO), [`src/main/java/org/example/dao/CourseDAO.java`](https://github.com/jaidmulla33-tech/universitymanagement/blob/main/src/main/java/org/example/dao/CourseDAO.java) (Course DAO)
