Document Management System (DMS)

Overview

The Document Management System (DMS) is a web application built using the MERN stack (MongoDB, Express.js, React.js, Node.js). The application integrates both relational and NoSQL databases to manage user authentication, workspace management, document handling, and more.

Features

• User Authentication: Secure user registration and login using a relational database (PostgreSQL/MySQL) with JWT-based session management.
• Workspace Management: Users can create and manage workspaces, each with its unique directory structure stored in MongoDB.
• Document Upload: Upload documents to a cloud storage system, with metadata saved in MongoDB.
• Document Download: Download documents securely, with proper authentication and authorization checks.
• Document Preview: Preview documents as Base64-encoded data.
• Document Deletion: Implement soft deletion of documents, ensuring data integrity.
• Document Listing: List documents based on workspaces and user profiles, with filtering and sorting options.
• Document Search: Search for documents by name or type using optimized MongoDB queries.
• Additional Features:
  • Document versioning
  • Document tagging
  • Document profiling
  • Granular access control

Technology Stack

• Frontend: React.js
• Backend: Node.js, Express.js
• Databases:
  • Relational Database: PostgreSQL or MySQL (for user authentication)
  • NoSQL Database: MongoDB (for workspace and document management)
• Storage: AWS S3 or other cloud storage services for document storage
• Security: JWT for session management, bcrypt for password hashing
• Testing: Jasmine
