About this class diagram for a blogging website

The UML class diagram for a blogging website shows key entities, including content creation, management, and user interaction.

At the heart of the system is the blog post class, which captures individual posts. A blog post has key parts: title, body, and post ID. It is linked to an author, represented by the user class. A blog post may be of a category, which aids in grouping content based on theme. The category class has properties such as name and description, and contains a list of blogs it is associated with.

The tag class offers extra metadata for blog posts so that posts can be tagged according to keywords. The relationship between tags and blog posts is many-to-many. This means a post can have multiple tags, and a tag can relate to many posts.

User interaction is provided through the comment and like classes. The comment class provides a method to add a comment to a blog post. The like class keeps a record of likes from users.

User management is done via the user and admin classes. The user class stores details like username, email, and password. It also keeps a list of blog posts they have written. Users can register, log in, update their profile, and delete their account. The admin class has the right to control users, posts, and comments for moderation and system administration.

The notification class is used to send messages to users, informing them of interactions like new comments or likes. Every notification has a message, a reference to the receiving user, and a timestamp. This UML class diagram creates an interactive blogging system. It handles content, engagement, and administration well.
