Briefly, the three tiers are the database, the application logic, and the user interface. If you build them properly, you can make the implementations independent of each other, which gives you the option of putting them on one, two, or three platforms.

Example: database: An Oracle database (tables, indexes, etc)

	 application logic: Oracle constraints, triggers, stored procedures
			    (or write it in some other language if you prefer)
	 user interface: SQL*Forms, or whatever you like (Visual Basic, etc)
