GIOD: Technical Goals
Explore and evaluate the advantages of Object technology
- Can ODBMS scale to PetaBytes of data?
- Find optimal OO language constructs for HEP
- To what degree is HEP data analysis facilitated
Determine the minimum WAN bandwidth links required
- How to group objects to optimise access speed
- How to link objects to optimise user queries
- How to minimise the amount of stored data
- How to minimise the amount of data being transported
- Explore performance limitations
Investigate data access methods and storage/transport strategies
- Measure the achievable level of cache (memory,disk,tertiary, etc.) hits
- Target improved caching strategies for the future
- Compare Fetch data, compute locally vs. Send query, compute remotely
- Criticality of the prevailing network conditions
Show how user code should be structured
- to best access the data
- to write object-oriented analysis
- to share new “private” objects with collaborators
