What is NODI?
Network Operations Data Infrastructure
A DWH Approach
Heterogeneous Environment
 Designed and Built for only
Network Operations Division
usage
 Various Vendors
 Combining network inventory,
performance, alarms, work orders,
customer complaints, configuration
and traffic in a historical way
Reporting
Statistical Methods
 Online and offline value added
reporting
 Real-time data warehousing
 Finding correlations and relations
between different operational
systems and making trend analysis
Why NODI?
Intelligent Combinations
Productive Network Planning
Decision Support
 Reporting idle equipments in
field
 Decision Support System in
Network Operations eco-system
 Lights a way from history to future
to manage network better and
increase performance
Trend Based Analysis
All-in-one Reporting
 Determining networking trends in
a timely fashion period
 Reporting different Network related
operational systems
 Integrating different kinds of data,
determining correlations and
relations

2. Drop flow table
3. Create flow table I$
4. Delete target table
5. Truncate target table
6. Analyze target table
7. Insert flow into I$ table
8. Recycle previous errors
9. Create Index on flow table
10. Analyze integration table
11. Remove deleted rows from flow table
12. Flag rows for update
13. Update existing rows
14. Flag useless rows
15. Update existing rows
16. Insert new rows
17. Commit transaction
18. Analyze target table
19. Drop flow table
Restructured Incremental Update Methodology
1. Drop flow table (I$)
2. Create flow table (I$)
3. Insert flow into I$ table
4. Flag rows for update
5. Create Unique Index on flow table (I$)
6. Update existing rows
7. Insert new rows

Data Mining ETL Reengineering?
SAS vs ODI
Need For Reengineering
6 years of development
Different analysts & developers
Continuously changing business
Continuously changing sources
How to change ?
Change data mining architecture
Leave SAS as mining engine
Data preparation in Oracle using Oracle Data Integrator
Redesign and Rewrite whole data mining ETL
