The Quotation Service gives you access to a list of quotations categorised by author's name. You can get a full list of quotations, get a list of quotations by author, or you can submit a quotation to the database. Here are the three service method signatures for the Quotation Service:

Quotation[] getAllQuotations ( );
String[] getQuotationsByAuthor ( String author );
void submitQuotation ( String author, String text );

Where the user-defined type Quotation is defined as:

Quotation
{
     String author;
     String text;
}
