Join Bill Weinman for an in-depth discussion in this video Touring the CRUD application, part of SQL Essential Training.
…CRUD is an acronym that stands for Create, Read, Update and Delete.…These are the four basic functions of a database systems.…This CRUD application is a demonstration of…how these functions work in a relational context.…This application demonstrates use of two tables that are related that uses the…same album.db database we've been using for examples in the rest of the course.…I'm just going to take you for a little tour through the application first.…You can see, here on this page, we display all of the albums in the database.…
So far, there's just seven of them, it looks like.…And for each of these albums, there's a title,…there's an artist, there's a label, there's a release date.…And you can edit or delete the albums.…We can go into one of these album by pressing…Edit, and you can see it brings up the album.…There's the album information at the top and the individual tracks down below.…If we want to we can correct something.…I left a mistake in here on purpose.…We can take that little x out and say update.…

Q: For Mac OS X: When I try to start the Apache Web Server from the XAMPP control panel, it doesn't start, and when I open "localhost" in my web browser, I see a white screen that says "It Works!" instead of the XAMPP page.
sudo apachectl stop
Q: I'm on a Mac, and I get an error in SID that says "attempt to write a read only database." How can I fix this?
A: This usually means that the database folder does not have sufficient permissions for writing by the web user. This can happen if you create the SQL folder new, rather than copying it from the Exercise Files. Here's how to fix this:
- Open a Finder window and Navigate to /Applications/XAMPP/htdocs/SQL
- Control-click on the SQL folder and select "Get Info" from the context menu.
- Under "Sharing and Permissions" (you may need to open the disclosure triangle), in the "everyone" row, select "Read & Write."Then you can close the Info window.
- Now repeat the process for the three *.db files inside the folder.
