specifications link together third party and local resources using web ser-
vice protocols. Taverna is a GUI used for assembling, adapting and running
workflows. Workflows that execute remote or local web services and Java
applications are the chief mechanism for forming experiments. Legacy appli-
cations are incorporated using myGrid wrapper tools. In addition to services
and applications, databases may be integrated using a query processor de-
veloped jointly with the UK OGSA-DAI project. An example of a myGrid
workflow is shown in figure 9.3. The software can be freely downloaded.

Summary

• Biology experiments and statistical analyses are transformation processes.
  
  
  1. A biology experiment transforms biological and chemical materials
     into quantitative measurements.
