Decision Support System (DSS)
The primary purpose of data systems is to mediate between data providers and programs/projects
Programs perform analysis for Orgs., the DSS is within programs
The big decisions of societal importance are done by Organizations
(This needs more wisdom from the practioners)

Not part of DataFed
Policy, Management, Personal Decisions
Special Architectural Features:
Implied data assimilation into models
Decision Support black box
Focus on model predictions, not ‘simulation’
Pollutant ‘Characterization’ is implicit

Flow of Data and Usage Control
Flow of Control
Reports are commissioned by programs
Analysts select, explore, and process data for a report
Data providers have generally little control over the end use
Flow of Data
Providers expose data to analysts who extract the needed subset
The data is pulled into data exploration or processing software
Some programs control their own data collection, others do not

• Data producers maintain their own workspace and resources (data, reports, comments). • Part of the resources are shared by creating a common virtual resources.• Web-based integration of the resources can be across several dimensions:
Spatial scale: Local – global data sharing Data content: Combination of data generated internally and externally
• Users can benefit from the pooled federated resources• The benefits of federation outweigh the costs.
