Why no automatic transfer to HR?Why no automatic transfer to HR?
Duplicates should be avoided at all cost in Oracle HR (there are implications in most AIS applications, cleaning takes about ½ day per case) but this is CERN’s interest only
Authorized HR-user should make a motivated decision for creation new Person in Oracle HR
Personnel data should follow strict rules (no accents, name as written on passport, etc)
Data creation in Oracle HR must be done on an individual case basis by specialized users!

Why semi-automatic transfer to HR?Why semi-automatic transfer to HR?
Avoid data re-entry as it generates
– Extra workload and time waste– Potential mistakes
Easy to use even for unexperienced users(no need to learn Oracle HR interface)

Problem with search duplicatesProblem with search duplicates
Last name can change (marriage)First name / last name mixed upIncomplete or incorrect data on any of 2
systems Different data formats (accents…)Typing mistakes happen oftenDifferent fields may have different

Get candidates Create person
Match candidates Get possible duplicates
CERNAIS
Basic workflow for e-RT Person MatchingBasic workflow for e-RT Person Matching
Check responsibility
Input criteria for searching candidates in the External Registration System
Retrieve candidates from the External Registration System
Find possible duplicates in Oracle HR for the selected candidate
Create new person in Oracle HR
Match candidate
[Such person is found]
[Else]
CERNAIS
How does it work ?How does it work ?
Uses existing PL/SQL engine to search duplicates in Oracle HR CRN_DUP+RETRIEVE_DUPLICATES(already used by OHR, PIE, PAD etc)
Person Matching integrates the PL/SQL engine with External Registration Systems (e-RT or others) and manages the workflow

What has been done (visible)What has been done (visible)
New functionalities added- restriction to specified jobs- selection of jobs from list or free-text- new combinations of searching- creation of private addresses in HR- time counters to monitor performance
Optimized database repository to increase search speed (function based index, etc…)
Many bugs fixed Web-design changed (slightly)
CERNAIS
What has been done (underlying)What has been done (underlying)
Code refactoring (such as encapsulation of logic, replacing and renaming classes and methods, extraction of methods)
Tools for audit (logging, page for statistics)
Prepared to be used with other External Registration Systems
Change of some database objects for better readability
CERNAIS
StatisticsStatistics
> 12000 candidates in e-RT > 200 candidates in e-RT per week > 164 000 persons in Oracle HR For the last week on Person Matching
> 265 persons have been checked> 75 persons created in Oracle HR> 190 persons matched with existing
Estimated time saving: 45 sec instead of 3 minutes per person for an experienced user
CERNAIS
What is next?What is next?
Try to develop a common Pre-Registration Tool for– External Firm Staff (to be used by firms)– Users (to be used by institutes)
Reuse Person Matching for– External Firm Staff Pre-Registration– Users Office Pre-Registration
Improve PL/SQL engine for searching potential duplicates
