@cmjackson26 9 лет назад

Thank you Caleb! This was super helpful! I was searching through Access help files and what I found wasn't nearly as good as your examples. Thanks!

What is the friking annotation for compound key and do I need to put it on a normalization form? the annotation is like a well hidden secret!

@Asimov16 7 лет назад

Can I use a composite unique key?

@Onizukaash 2 года назад

Your intro is kind of primary key👀

@bilalfawadkhan 4 года назад

Very Well Explained , I like the way you Explain it especially using chalk Adds the effect of Interest since everybody uses marker and they move tooic very quickly , Using chalks gives me time to absorb of what u said 👍.

@kamilo1175 3 года назад

@bilalfawadkhan 3 года назад

@rodrigosilveira6886 7 лет назад

If email would always need to be unique, why would you composite the key on (fn + ln + email) instead of just using the email?

@ayubsharif7359 7 лет назад

lets say the email is not unique. then it has to be composite, its just an example my friend :)

@metdelta1 6 лет назад

Rodrigo Silveira Very well said 😂👍

@javar1987 7 лет назад

@mahmoudabukhadier5605 8 лет назад

I don't know why but it bothers me that your chalk is so small, otherwise good video.

This is what happens when you just record without preparing. -1

@Que2701 9 лет назад

CalebTheVideoMaker2 lol++ liar liar pants on fire. don't you mean it took you 2-3 months to come up with better example of a composite key in M:N relation? o_O
