Trying to figure out databases. I am confused. Okay there's the client, say, a library patron trying to find a book from their own personal computer. The patron's computer is the client. They go online to the library's web site and navigate to the library's online catalog, which has some boxes to enter the title and author, call number, etc. The patron types in the title: The Road Less Traveled. The library's server does something. What? It turns it into a query or something. The library's database management system processes the words the patron types in and turns it into a query that looks like what (I don't know). The query goes to the database which is located where? On some server computer somewhere. I guess the database will have a record that has Title, Author, Call Number, What libraries in the system own the title, and then of those, which ones have one available. It might also have other details like other formats the title is in like CD, audiotape, etc., whether it is on some special status, like it can only be checked out for two weeks or something. The database doesn't "do" anything, does it? It just sits there with the data, right? And it's the Database Management System that sorts it, and then the web server puts it into a readable format and renders it into a sort of temporary web page that it sends over the internet back to the patron.
