Claremont Report on Database Research: Research Directions (Beng Chin Ooi)

Structured P2P based Data Management for Corporate Networks Beng Chin Ooi National University of Singapore

Corporate Network Applications
National/regional/global Supply-Chain-Management 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

Query form interface Conventional Data Sharing (eg. SCM between companies) Data engine Supplier ERP Database Trader ERP Manufacturer ERP Traders Wholesalers Transporters Retailers Problems: Expensive (huge initial investment on S/W and H/W) Expensive Maintenance Scalability

Structured P2P based Data Management (eg SCM) Structured P2P network/ BATON ERP Peer Node

Processes export data create index insert index insert index incoming query query result

Sharing of Data Local schema Configurable global schema firewall Mapping Index . . . Querying Update chipset code l_width die size cost Clawhammer 90 nm 64 mm² $100 chipset ID linewidth die size Clawhammer 90 nm 64 mm²

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?
Query Processing
SQL queries (to what extent of complexity?)
Status
Implementation of 2 nd version ongoing
Features
Peers are stable in corporate Networks
Data mapping is easier (with some manual wrapping)
Simpler queries
