    props to this guy for learning to write backwards just for us

    Just gotta say - the longer I got into the video the more I thought about how you write backwards and less about databases haha. But great explanation. Thank you:)

      I guess that you flip the screen?

      Maye but you'd have to record him twice, otherwise you'd be recording the back of his head
      also ur guess is better than mine wi think. Mine was that he had a sort of teleprompter...but like, with GIFs of what to write when, rather than script

    I thought maybe he recorded this writing normally and afterward they flip the video, but his wedding ring is on his left hand so I think he really is writing backwards. That's crazy! Great video :)

    Simple and easy to understand. I also like the examples as it makes more sense of the benefits of a relational database. Much appreciated!

    Blessed Day to you, Jamil Spencer! I am a keyboard specialist who is also a fan of modern microcomputer technology. Believe it or not, Microsoft Access is my favorite kind of program. I have been using it, since I used the 2002 edition in the Microsoft Office XP Professional suite with my first microcomputer. Microsoft Word has been my springboard because I practice my old-fashioned typewriting skill which is keyboarding, since I learned typewriting when I was 12 years old. Today, in the year 2024, I have Microsoft Office 2021 Professional with a Dell OptiPlex microcomputer that works Microsoft Windows 11 Professional. I do not know many people who use Microsoft 11 Professional, let alone Microsoft 365 or Microsoft Office 2021 Professional. Also, I print some work on laser paper with a Canon color laser printer, and some lists that from my Access databases are put forth into a label making program in my Brother P-touch label tape printer that I use to print professional-looking laminated label tapes. Yes, Microsoft Access is a relational kind of database program. I believe that Microsoft Excel makes an excellent flat file database set, but Microsoft Access makes the best relational database program as my favorite. I am pleased to watch your show, even though it is too brief for me.💙

    I'm genuinely torn on whether or not I love that you didn't mention many-to-many relationships! Lol
    Because, on the one hand, if you build your database ***right*** you should almost *never* have many-to-many relationships, so it may be wise not to even mention as an option.
    On the other hand, many-to-many relationships are extraordinarily common, so it may instead be wise to acknowledge their existence, even if for no other purpose than as a warning.
    Even in your example, books and authors DO have a many-to-many relationship (a person can be an author of multiple books, and a book can have multiple authors).
    In such a case, the only way to avoid having a many-to-many relationship in your database, you must first recognize that the objects your storing DO have, conceptually, a many-to-many relationship!
    Anyways, great video!

    select * from books; can not be interpreted as select all books from books. It acatully means select all fields of book from books.

      He then says “..to give me ALL this data out for me to use”. So, I think he meant that but yes his wording was a little off.

    Does sql server provides multi user access to support many storage engines?

    Gotta be just mirrored in editing right?

    So, he's either left-handed or he wears his watch on the right wrist which is odd.
