Hello
I have been given a task to normalize a data structure which is used to fill a form that contains information about the company applied to, such as the role and required strengths/qualifications.
It will also contain my strenghts, qualifications, cv , outcome etc.
Thing is, I don't exactly understand the normalization process, I did bring the unnormalized structure into 3rd normal form, however I'm not sure if i've done it correctly.
I'd appreciate if you could look over it and eventually suggest any improvements.
Thank you.
