A client computer collects registration information and uploads the
collected information to one or more remote registration databases. The
collection and/or uploading of registration information for multiple
manufacturers is performed in a unified manner, improving the
user-friendliness of the computer. According to one aspect of the
invention, a single user interface is used to collect the registration
information for all of the manufacturers, preventing the same question
from being asked multiple times. According to another aspect of the
invention, a multiple posting method is used to upload the registration
information to the registration databases. In the multiple posting
method, a single network communication link is established between the
client computer and a network that the registration databases are coupled
to, via which multiple client computer to registration database
connections are established.
