About This Architecture

Forum application ER diagram modeling a multi-table relational schema with User, Profile, Role, Category, Topic, Thread, Reply, Favorite, and ThreadLike entities. Data flows from Users through Profiles and Roles, then into hierarchical forum content: Categories contain Topics, Topics contain Threads, and Threads contain Replies with optional parent-child nesting. The schema supports user authentication, role-based access control, content engagement tracking (likes, favorites), and multilingual support (Arabic, French translations). Fork this diagram on Diagrams.so to customize for your OCI database deployment, add indexes, or extend with additional entities like notifications or moderation flags.
