Hello all,
I need to make a simple database, and then some windows application (possibly C#) connecting to it... but first...
First I need to design and model a good and functional database, right?
So I am stuck in it now :) and please help if you can. I dont want you to do my homework, all I need is to get some guidance...
Lets say, I have a table called Students.
Columns in Students table are: student_id, name, last_name, email, and so on....
Columns in Professors table are: professor_id, name, last_name, email ... etc....
there are other columns that should be there, but I am not sure whether they should be put in a separate table... for example: knowledge of foreign languages: which_language, proficieny_writing, reading, talking ....
Both tables, Students and Professors need to have information about the knowledge of foreign languages.... so how do I accomplish that? If I am talking about students, I can make columns in foreign_languages table like: lang_id, student_id, language, writing, reading, talking
but what about PRofessors?? I need to put their knowledge of foreign languages too... but where?? :)
do I have to make a separate foreign_lang_prof table?
I am really confused.... and I hope I explained myself and didnt bore you :) Thanks in advance!!!!
