DB
The database uses a dual-table architecture with a one-to-many relationship between Project and Document.
The Project table stores basic project information, including project name, contact phone number, and application address;
The Document table records detailed document data such as document name, issuing agency, file path, review status, and upload time.
The two tables are linked via the project_id foreign key, enabling hierarchical management of projects and documents while keeping the data structure clear and easy to track.
