Networks

Corporate Network Applications
• National/regional/global Supply-ChainManagement and Product Tracking
• National Health Care…
• Purpose: mainly for information
sharing/pulling
Requirements for Becoming a Disruptive
Technology to Corporate Networks
• Enterprise Quality Data Processing
– Secure
– Efficient
– Accurate
– Must appear as if it is a centralized ERP or DBMS
• Scalability, Adaptability, Maintainability
• Synchronization (map out from individual
server to respective peer node), but no ACID
enforcement
Conventional Data Sharing (eg.
SCM between companies)
Database
Traders
Trader ERP
Wholesalers
Data engine
Manufacturer ERP
Problems:
Supplier ERP
Transporters
Expensive (huge initial
investment on S/W and
Retailers H/W)
Query form interface
Expensive Maintenance
Scalability

Research Issues
• Structured P2P Overlay Protocols
– Range based indexing/routing
• Garbage collection is expensive
– Load Balancing
• Indexing
– Just-in-time indexing
– Partial indexing based on range/summary/histograms
– Indexing many attributes?
Features
• Query Processing
– SQL queries (to what extent of complexity?)
• Status
– Implementation of 2nd version ongoing
•Peers are stable in
corporate Networks
•Data mapping is
easier (with some
manual wrapping)
•Simpler queries
