To access the CD Database Server preference tool, click Launch, then choose Preferences -> Desktop Preferences -> CD Database Server.
The CD Database Server
preference tool enables
you to configure a CD database server that your system can query. A CD database
server contains information about CDs, such as the name of the artist, the
title, and the track list. When an application plays a CD, the application
can query the CD database server about the CD, then display the information.
Table 7–3 describes the
preferences in the CD Database Server
preference
tool.

To access the File Associations preference tool, click Launch, then choose Preferences -> Desktop Preferences -> File Associations.
Use the File Associations
preference tool
to configure the following:
You can specify how files of various types are displayed and edited. For example, you can specify an icon to represent a particular type of file. For another example, you can specify that if a file is a plain text file, the file is launched in a text editor.
The file manager and other desktop applications check the contents of a file to determine the type of a file. If the first lines do not determine the type of the file, then the application checks the filename.
A Uniform Resource Identifier (URI) is a string that identifies a particular location in a file system or on the Web. For example, the web address of a web page is a URI. A service is a protocol or task that a URI requests. For example, the http://www.gnome.org URI requests the http service.
You can associate an application with a service, so that the application performs the task required by the service. For example, you can associate your preferred web browser with the http service.
