Question

In my PhpMyAdmin database I have 9 tables. 8 of those tables are relevant to me at this moment. I would like my queries to be executed quickly enough but I am not sure the design/structure of the tables are the most effecient. Any suggestion of merging a table with another or creating another bridge table? Also, I am struggling in building a query that will display bridge results from the following tables: semester, schedule, office_hours, faculty, section, major_minor, major_class_br, class?

TABLE STRUCTURE

Basic Query- that shows class details

SELECT  class_name, class_caption, class_credit_hours, class_description
FROM class  

Answer 1

Here’s a start:

select *
from 
schedule 
inner join semester 
on schedule.semester_id = semester.id
inner join office_hours
on office_hours.id = schedule.???

It’s not clear how office_hours correlates with schedule?
