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

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

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
