MYSQL / PHP-将用户附加到项目的有效方法

Question

I'm building a system that has a user table and a project table. I'm trying to determine the most efficient way to connect users to a project.

I'm was thinking about a table that records the relationship, but I wasn't sure if a serialized list in one field would work just as well.

Answer 1

A join table (eg UserJoinProject ) would be my preference and would be well normalized. Assuming you have an ID column as a primary key for projects and for users.

Serializing the list will make it difficult for mysql to do any kind of operation on that data.

Answer 2

如果是多对多关系，则可以创建另一个表，该表仅将项目ID与用户ID相关联。
