People, I want to design a historical sports db for my old school. I think at the moment it should be like: A year has many teams A team has many students A student has one lastname, firstname and middlename but a student can also have many teams (eg summer/winter abd over a number of years) . . Is there a problem with this? Doesn't it just mean that there will be a student table with: id lastname firstname middlename and a separate "studentteams" table with: id student_id team_id ? Thanks, Phil. -- Philip R.

Hi Phil, It seems to me that each of those set could have a many-to-many relationship to both of the other sets - coding them just depends on whether people really care about what teams played in year xxxx or what years Johnny XXXX played in. Check out this page for these "has and belongs to many" relationships: http://wiki.rubyonrails.org/rails/pages/has_and_be...
