    Weak and strong relationships

    Can anyone please explain to me the differences between weak and strong relationships and how they would appear differently in an ERD model? I tried to explain this to my students and they seem extremely confused.

    fairly decent presentation

    here's the url to the actual PPT file --> E-R Modeling

    either your browser can read it directly, or you can download it as a PPT file and open a viewer

    it reads a lot better in the original format
