The apparent facts:
- You're enrolled in a CS class in school.
- You don't know any programming languages (presumably including SQL).
- You don't know MySQL Workbench.
- Your CS assignment is to make a database for a small business.
Given the above, why not just use Filemaker?
Or is one of the requirements for the assignment that you must use MySQL?
What tools does the CS class expect you to know?
If MySQL Workbench is one of them, then you should do some studying. If not, then use the tool from the class.
I'm having a hard time seeing how anyone would be able to do this assignment without knowing a programming language, except by using database programs that require no programming. MySQL Workbench is a visual designer for MySQL, but if you don't know how to use it, it's no more help than any other program you don't know how to use. The obvious question then is: "What database tools do you know how to use?".
