I need a Chen-style ER diagram for a Database Management Systems project (Movie Database System). The diagram should include the following entities: User, Content, Movie, Series, Episode, Review, Category, UserGroup, and AccessLevel. Requirements: - Use proper Chen notation (rectangles for entities, ovals for attributes, diamonds for relationships, triangle for ISA). - Content must be generalized into Movie, Series, and Episode using ISA. - Series should have a relationship with Episode (one-to-many). - Include a review system: User writes Review, and Review is linked to Content. - Content should be categorized using Category (many-to-many). - Implement access control: - Users belong to UserGroups. - UserGroups have AccessLevels. - Content requires an AccessLevel. - AccessLevels can be nested (recursive relationship). - UserGroups can also have recursive relationships (group hierarchy). The diagram must be clean, properly labeled with cardinalities (1:N, M:N), and follow academic ER modeling standards. Deliverable: A neat, well-structured ER diagram (hand-drawn style or digital) suitable for academic submission.
