## Overview

The available source describes a small car-rental administration API: an administrator-facing REST controller delegates order, store, and user operations to service interfaces. The README instead documents a university leave-management system, so its capabilities cannot be reliably mapped to these files. The graph reflects only the three excerpted controllers and their explicit service calls; service implementations and persistence are not present in the supplied tree.

Main entry points: [`OrderManageController.java`](https://github.com/zhangsan594226632/university-student-leave-management-system/blob/main/OrderManageController.java) (Order management), [`StoreManageController.java`](https://github.com/zhangsan594226632/university-student-leave-management-system/blob/main/StoreManageController.java) (Store management), [`UserManageController.java`](https://github.com/zhangsan594226632/university-student-leave-management-system/blob/main/UserManageController.java) (User management)

## Components

### Admin API

- [Order management](https://github.com/zhangsan594226632/university-student-leave-management-system/blob/main/OrderManageController.java): `OrderManageController.java`
- **Order service**
- [Store management](https://github.com/zhangsan594226632/university-student-leave-management-system/blob/main/StoreManageController.java): `StoreManageController.java`
- **Store service**
- [User management](https://github.com/zhangsan594226632/university-student-leave-management-system/blob/main/UserManageController.java): `UserManageController.java`
- **User service**

### Other components

- **Administrator**

- Order management → Order service: delegates operations (evidence: `OrderManageController.java`)
- Administrator → Store management: calls REST endpoints (evidence: `StoreManageController.java`)
- Store management → Store service: delegates operations (evidence: `StoreManageController.java`)
- Administrator → User management: calls REST endpoints (evidence: `UserManageController.java`)
- User management → User service: delegates operations (evidence: `UserManageController.java`)
