An interface is a specification of behavior that implementers agree to meet. It is a contract. By implementing an interface, classes are guaranteed to support a required behavior, which allows the system to treat nonrelated elements in the same way, through the common interface. An interface cannot be instantiated (i.e., you cannot create an object from an interface). You must create a class that implements the interface specification and place operations in the class body for each of the interface operations. You can then instantiate the class. Interfaces may be drawn as a stereotyped class, with operations shown. They may also be drawn as a circle with no explicit operations detailed (see Figure A-2).

The GetAuthorDataSet() method includes all the caching logic. If the DataSet is in the cache, it returns it immediately. Otherwise, it queries the database, creates the DataSet, and inserts it in the cache. The end result is that both web methods can use the same cached data.
