Welcome to lesson three. This’ll be databases. Databases are how you actually store all those information that we’ve been collecting from users. This is basically the final piece that’ll allow us to build fully functional web applications, and your homework for...
And the answer I’m looking for, obviously, is the thing we just talked about– replicate the database. Now, yes, you can get a faster machine, but sometimes you don’t have access to a faster machine, and that’s obviously not what I...
Thought I’d take a moment real quick to explain how ad networks work. This isn’t strictly relative or relevant to this class but it’s kind of a neat example of how cookies are used. So say you have your browser and...
Okay, so we just ran some queries on our list of 25 links by hand, and that was a little tedious, so what are some of the downsides of querying data by hand? Now, I know we only had 25 links...

All right. Let me show you how the Template works, real quick. I’ve got this file called front.html. It’s currently blank. I’m going to type in some HTML. We’ve got our DOCTYPE–you know– our , our /ascii/, We’ve got our here,...
We’re going to make this change to the app we’ve been working on, and we’ve got to do two things. We need to make a thanks handler. We need to add the thanks URL, and we need to redirect to the...
Okay, the next question was about larger applications where you inherently have to deal with more than one table. Earlier in the course you mentioned that doing joins was a very bad idea and could be very expensive. How do you...
Okay. Now one thing to note here is we have our radio buttons and how is the user to know which is which? They’re just 3 anonymous radio buttons. Well, that is what the element is for, and I’ll show you...
The answer is HTML. While all of these things can exist on the web, any type of file can be linked to. HTML documents are the, the basis for everything on the web....
