Car Wide Web
The Car Wide Web is the module responsible for the retrieval of the data
needed by the system. Almost all the dialogue that takes place between the
system and the user is based on information resident in databases, which can
be static or dynamic. A static database may contain historical information
regarding a city being visited; a dynamic database (through an Internet
connection) may contain weather forecasts or could allow a restaurant
reservation. CWW primary task is to understand the queries coming from the
DM and to retrieve the data from the databases. The actual connection to the
data is delegated to a specific API (see Section 2.6), so CWW maintains a
certain independence from the physical structure of the databases.
