The software framework for Atlas. Based on GAUDI, ATHENA provides common services such as the transient data store, (interactive) job configuration and auditing, data(-base) access, message streams, etc. for Atlas software. The idea is to improve the coherency of the different software domains within Atlas, and thereby the ease of use for end-users and developers, by having them all use the same well-defined interfaces. For more information, see the Atlas architecture site. See Also GAUDI.
