You can think of the features
of Notes as they exist in releases as the
"core" Notes functions and the types of applications
that Notes can accommodate as the "core" Notes
applications.
Those features can include
shared, document-oriented databases, messaging,
strong security features, distributed data
kept in-sync through replication, support
for mobiles, disconnected Notes users and
access to non-Notes data. The applications
can include information repositories, discussion
forums, project tracking applications, and
business process or "workflow" applications
