Data management
Many kinds of data in FloodGrid– Meteorological, hydrological, hydraulic– Generated by simulations or obtained from sensors– Permanent or periodically updated– Publicly available or with restricted access
Using metadata catalog for describing data Data are stored in storage elements and are
accessed via Grid protocols Operation: query, adding, modification, deleting
MIPRO Conference,Opatija, 31 May -3 June 2005

Workflow management
Manages and executes jobs with data dependences
Cooperates with Resource Broker to find suitable computing element for running simulation
Monitors status of jobs Abilities to use predefined workflow
templates, spawning running workflow, modifying parameters of jobs
