okay I'll try to explain an best I can...

I am building a database with education certificates, 4 certificates. Each certificate has 4 courses. Each certificate will be offered 4 times at different dates. An applicant can sign up for courses at different times. So, Round 1 Certificate 1 and Course 1 & 2. Then they can come in Round 2 and take Certificate 1 - Course 3 & 4 and so on...

How can I set up the DB. I have a Rounds table: 4 rounds. I have a Certificates Table: 4 Certificates and Each Certificate has 4 Courses. I am confusing myself being newer to this.

If there is anything that will help, a link to info, a hey think about it this way...

Anything to get to think more clearly would be great!

Thanks
Tim
