Blog
This doc introduces a typical data model design example for blog.
A blog should allow users to create articles, comment on them, bookmark their favorite content, and manage their personal profiles and interaction history. This requires setting up data access and permissions to ensure content visibility is appropriate and user privacy is protected.
