Claims Service-Oriented Architecture Performance Prototype

Team Hooloovoo

Team Information• Team Members

– Jaden Bruun– Jason Cavett– Justin Glaser– Erik Raisanen

• Sponsor– Eric Stephens

• Advisor– Robert Bubacz

Project Description• Project Background

– Claims Processing– Performance vs. Modifiability– New Solution Required

• Investigate Performance– Develop Prototype– Investigate Performance

Improvements

Process• Baseline Development• Three Iterations

– Caching– Threading– Distributed Services

Metrics• Performance

– Processing Time– Memory Usage– CPU Usage

• Effort– Man Hours– Function Points

Baseline• Processing Claims

– Validate the Claim– Retrieve Claim History– Determine Member Eligibility– Provider Validation

Iteration 1: Caching• Java Caching System (JCS)• Aspect-Oriented Programming

– Spring Framework• Dynamic vs. Static Caching

Iteration 2: Threading• EJB Specification v2.1

– “The enterprise bean must not attempt to manage threads.”

• New Solution– Remove EJBs– Thread per Service

Final Results

Recommendations

Project Assessment: Problem Areas• Distractions• Poster Presentation• Threading

– Specification Restriction– No Mitigation Plan

Project Assessment: Working Well• Solid Team• Sponsor Communication

– Bi-Weekly Conference Call• Working Sessions• Dual Core iMac

The Project’s Future• Service Initiative

– Implementation of Core Services– Provider and Product in Production

• CSOAPP Saves Excellus Time– 6 Months of Work

• Value with Use
