Data modeling and Relational Graph

Hey there,

I'm still in the learning process (well, it will never end 😉). I created my first database (music database for sheet music and albums), with many layouts, and entered a lot of data (2500+). At the same time, I've been watching Richard's live training videos. My main problem was the data modeling part. So now that I know better, I have to clean the relationships and update my layouts, etc., IOW, apply what I've learned over the past months.

Question: should I edit my 1st solution, duplicate/update base tables or TOs, update relationships, edit layouts / create new layouts? Or should I create a new solution and import the data from the old file?

Thank you in advance for your tips!
