CCP03 Review
“NRFU POC”
Date: 09/12/2007

2. CCP03 Background History
Mainframe applications supporting DRIS function have proven reliability and performance to support decennial activities
Future systems architecture will leverage Oracle RDBMS in places where mainframe computing has been used
Initial efforts to convert specific business functions to Oracle have failed to provide required performance, and have negative implications to adoption strategy for new technology
CCP03 chartered to conduct POC on specific functions (NRFU) in support of Oracle adoption effort for DRIS team

3. CCP03 Completed Efforts System/Application Study
Evaluate Existing/Initial Implementation on Oracle
Determine performance drivers on initial development platform
Evaluate Physical Design as Initially Deployed
Migrate Specific Functions to Enterprise RDBMS Platform (UC&M and UECT)
Load data
Validate
Performance tuning

4. CCP03 Completed Efforts Functions
Build UC&M data application
Update Logical Data model for use on RDBMS
Create Physical Data Model (DDL creation)
Deploy to both old and new Oracle platforms
Execute performance comparisons between platforms
UECT creation from UC&M
Update Data model and create DDL
Data extract based on State
UECT Validation/Compare
Partitioning approaches
Full data extract for 2000 (state level)
Simulate for 2008 run (LCO level)

5. CCP03 Ongoing Efforts Create RPS Processes Analysis and design
Update Data model and create DDL
Study Functions and create extracts
Execute performance comparisons between platforms

6. Major Tasks for RPS… Data Conversion
Census 2000 T13 data to Universal Response Database Schema
Post external interface data import and processing
Preceding data to be used to refine the RPS table design
URdbS response data tables will be further utilized as input to derive processing component metrics.
Performance and tuning will be done for RPS applications.
