Technical Stack

• Language: C#
• Framework: .NET Core / ASP.NET Core API
• Architecture: Layered Architecture (Separation of API, Business Logic, and Data Access)

System Architecture

The project codebase is organized into dedicated layers to abstract core business functionality from data access and delivery:

• SmartStore.API: The entry point of the application, containing controllers, middleware, and API endpoints. It handles incoming HTTP requests and structures responses.
• SmartStore.BLL (Business Logic Layer): Houses the core system functions, processing logic, business rules, validation, and permission evaluations.
• SmartStore.DAL (Data Access Layer): Directs interaction with the underlying database, managing data retrieval, persistence, and storage operations.

Core Features

• ** Hierarchical File System:** Supports creating, renaming, and structuring files and folders within a multi-layered workspace directory.
• ** Access & Permission Control:** Granular authorization system allowing users or administrators to assign, update, and revoke rights on specific folders and individual files.
• ** Trash & Recovery Workflow:** Secure file deletion framework enabling users to move items to a trash repository, restore them, or perform permanent deletions.
• ** User & Group Collaboration:** Capability to group users into structural units to manage shared access to document libraries seamlessly.
• ** Version Control & Logging:** Basic audit logging mechanism to monitor document modifications and store structural changes over time.
