# 📝 **LCBP3-DMS Documents Management System Version 1.4.2: Application Requirements Specification (by DeepSeek)**
|
||||
|
||||
* **ปรับปรุงตามข้อเสนอแนะจาก FullStackJS Guidelines และแผนการพัฒนา**
|
||||
|
||||
## 📌 **1. วัตถุประสงค์**
|
||||
|
||||

|
||||
|
||||
* มีฟังก์ชันหลักในการอัปโหลด จัดเก็บ ค้นหา แชร์ และควบคุมสิทธิ์การเข้าถึงเอกสาร
|
||||
* ช่วยลดการใช้เอกสารกระดาษ เพิ่มความปลอดภัยในการจัดเก็บข้อมูล
|
||||
* เพิ่มความสะดวกในการทำงานร่วมกันระหว่างองกรณ์
|
||||
* **เสริม:** ปรับปรุงความปลอดภัยของระบบด้วยมาตรการป้องกันที่ทันสมัย
