A server, having an automatic management mechanism, automatically delivers a
request
for license from a user to a communication window, automatically arranges information
such as titles of software parts, keywords of the software parts, etc. in a hierarchical
structure, performs a certification only when a user access a web page for which
a certification is necessary, or automatically extracts, from a document such as
a specification or a manual, an explanation of a software part to be registered,
whereby the procedure for arranging images is automated, the process for certification
is simplified so that the time necessary for the certification procedure is shortened,
and the time necessary for a user to wait until the explanation becomes useable
is shortened.
