In order to design a database schema for the forum, you need to consider the following key aspects: User information: store the basic information of forum users, such as user name, password, email, registration time, etc. Post information: record the title, content, publishing time, number of likes and comments of the post. Plate information: store the plate name, description, creation time, etc. Post classification: Determine which boards can publish which types of posts, for example, the technical communication board only allows posts related to technology.Comment information: Store the content of the comment, the time of publication, the commenter, etc. Reply information: store the content of the reply, the time of publication, the respondent, etc. Points system: record the user's points, which can be used for posting, commenting and other operations. Permission management: set the corresponding permissions according to the user's role (such as ordinary user, moderator, administrator, etc.). When designing a database schema, you need to consider the following questions: What are the relationships between database tables? For example,There is an association between posts and boards, and there is an association between users and posts and comments. How to set up primary and foreign keys? For example, a primary key in a post table may be a unique identifier for a post, a primary key in a board table may be a unique identifier for a board, and so on. How to ensure the consistency and integrity of data? For example, when a board is deleted, related posts are deleted; when a user is deleted, related posts and comments are deleted, etc. How do I optimize query performance? For example, use indexes to speed up queries
