MIKS is an Agent mediator-based system for
integrating multiple enterprises’ data sources into a
single portal system.
Distributed information stored in multiple,
heterogeneous sources

• Semantic reconciliation of multiple heterogeneous ontologies
• Information fusion and query Agent support
• Mobile Agents support in order to improve system
flexibility and query performance (based on JADE)

Discovering the relevant local sources
Query rewriting w.r.t. local sources
Independent local data retrieving
Unified data answers
In MIKS (WINK Integration Framework):
– OQL-like query over GVV
– Query Reformulation/Optimization
– Local sub-queries execution
– Mediated query result obtained by object fusion

WINK
User Query:
Select Activity, Effort
from Activity
where Requirement=‘IC-5’
and Closed=‘Y’
AIVDB: Q1
Select PROD_ID
from VER_DOC_LINK
where REQ_SEQ=‘IC-5’
and REOPENING=‘Y’
Università
di Modena
e Reggio Emilia
GVV
WHALES: Q2
Select Activity, Effort, Test_ID
from Work_Plan
Fusion
Select Activity, Effort
from Q1, Q2
where Q1.PROD_ID= Q2.Test_ID

WINK
Expected advantages:
• Agent Mobility
– Distributed computation
– Decreased communication costs
– Increased information availability even during network failure
• Mediation: Intelligence and coordination
– Semantic view of the physical query
– Enables asynchronous processing
– Warning on source data structure changes
