UCCSC 2014 UCPath Common Data Warehouse

 A cornerstone project of the UC Working Smarter Initiative  Standardize and streamline payroll and human resources processes system-wide  Replace UC’s 35-year-old payroll/personnel system (PPS) with Oracle’s PeopleSoft Human Capital Management (HCM) 2

 Oracle PeopleSoft HCM is architecturally distinct from PPS  Significant revisions/replacements of existing PPS-based data warehouses for all Locations  Data warehousing is not part of UCPath  Data warehouse solution left to each Location 3

 ITLC subcommittee with membership across UC ◦ Define direction & establish priorities for system wide data services and business intelligence  Recognized the opportunity for Locations to collaboratively design and develop a UCPath Common Data Warehouse  Developed and successfully championed the project proposal funded through the Office of the President 4

 Ensure efficiencies gained through collaborative design & development among all UC Locations  Design once – reuse many Assumptions  UCLA’s existing UCPath DW will serve as initial basis of design  Design will adhere to “standard star schema” – Kimball’s dimensional modeling practices 5

 Fully attributed logical and physical dimensional data models  CDW data dictionary  Multi-platform DDL - Oracle, SQLServer & DB2  ETL specification mapping  Core set of reports, requirements and analytic algorithms 6

 Person/Employee  Job  Absence Management  Labor Ledger  Payroll/Commitment Accounting  Benefits  Budget Ledger  Job Position Management 7

 BICG Co- Project Leads (UCOP, UCLA)  Project Manager  Core Team ◦ 3 Data Architects (UCB, UCLA, UCOP) ◦ ERwin Data Modeler ◦ Reports Developer  Extended Team ◦ UCPath Functional Experts ◦ Location UCPath and DW Experts 8

 Work one subject area at a time ◦ Gather use cases from Locations ◦ Review, identify issues, work with functional experts, and revise UCLA dimensional data models as needed ◦ Hold Design Review Sessions with all Locations to review deliverables ◦ Follow up with comments received, resolve issues and make final revisions ◦ Publish deliverables  Hold to Kimball’s dimensional modeling design practices 9

 Oracle HCM is new to UC and UC custom- izations to HCM are still being implemented  HCM data model does not contain referential integrity ◦ Data relationships, business logic enforced by application ◦ Dependency on functional experts  Location requirements, design practices, environments and tool sets are different 10

 UCLA’s existing UCPath dimensional models serve as basis for CDW Version 1.0  Able to leverage the method of Location collaboration and the knowledge gained about HCM from previous work on UCPath DDODS  Able to leverage knowledge about HCM from Locations that have already implemented HCM 11

 Designs for Person, Job and Absence Management are complete with data dictionary and ETL specification mapping  Use cases provided by Locations have extended UCLA’s models to meet common as well as Location specific design requirements  Full text data naming in logical model with optional abbreviation algorithm for physical naming provides naming flexibility and an opportunity for short name standardization 12

 Collaboration Works!  The common solution IS a collaborative solution  Immediate gains are all due to collaboration  All Location alternatives contribute in whole, in part or generating new or hybrid solutions  Takes work! Team work! Communication!  Holding to Kimball’s dimensional modeling practices established the design paradigm, facilitating communication and progress 13
