i need some help on some problems regarding database design that i build right now.
currently, i'm doing my project and at the phase for designing the effective and efficient database for small clinic.
where should i ask this question?
Not to be unkind, and I did answer your other question, but database design is a big subject with few absolute answers. There are many books and on-line tutorials available, but there is no substitute for experience.
It has been my hard learned experience that starting a project without understanding your basic tools is bad. I make it a rule to never start a production project with a new tool. The probability is that you will encounter exceedingly slow progress, if not outright failure.
