Database development was complex, resource intensive, and time consuming.
Semiautomatic interactive graphic tools were critical. They allowed us to work
paperless and facilitated international cooperation via Internet. Project
benefited from the expertise, resources, and experiences of the research groups.
Samples of the database will be available on http://www.physionet.org,
while the database will be published on CD-ROMs and will be released in the
spring of 2001.
