CiTRs DECADE Strategy

• DECADE vision
• integrated electronic customer access
• independent of the UI technology
• independent of the application domains
• DECADE Environment
• Many UI Technologies
• Isolated Business Logic
• Many Implementation Technologies

3
Internet Billing Application

• Call Preview - First telecommunications internet
  billing application in Australia
• Allow customers to access bill details via a Web
  Browser
• Call Preview developed using DECADE
• System must be able to eventually support up to
  1000 concurrent users
• ECA adds value to basic Call Preview service

5
Service Architecture

• Based on TINAs Service Architecture
• Core Components
• User Agent
• Login Manager
• Combined Service Session Manager
• Service Factory

6
Meeting Scalability Requirements (1)

• Scalability addressed by Computing Architecture
  and Service Architecture
• 3 tier architecture

7
Meeting Scalability Requirements (2)

• Cluster Management
• Cluster
• Cluster Container
• Cluster Factory
• Implemented in computing architecture
• Limits inter process communication
• Minimises resource leaks

8
Meeting Response-time Requirements

• Generating HTML pages on-the-fly
• Thin clients - no processing done on client box
• New functionality and services available
  immediately
• CORBA platform under load

9
Deployment

• Interfacing to systems
• Web Servers
• Firewalls (routers and Security constraints)
• Backend Databases
• Orbs
• System Requirements
• network setup
• common environment from Test to Production

10
What we Learnt

• Requirement for shakeout period
• Integration not easy
• Real user testing required, not just automated
  tools
• GUIs with C not quick fixes - maybe Java would
  have been easier??
• CORBA Servers need to be VERY robust in a high
  use environment
• Customers are usually BIG organisations, which
  affects the turnaround time for problems

11
Future Work

• Additional user functionality
• CSV export
• Enhanced sorting and filtering
• Web based reporting for CSRs
• how many customers accessing certain
• usage of functions
• Improve ability to change GUI characteristics
  quickly
• for enhancement
• for new clients!

12
Conclusion

• Internet application provided within short
  timeframe
• Understanding of the types of architectures
  required for similar applications
• Implementation of DECADE architecture
• Experiences learnt interfacing with one of
  Australias largest companies
