Cost & Risk of Modernisation

Inherit Legacy Problems

Not A Modern Application (Actually Legacy Emulation)

No-one recognizes the output

Virtually Un-maintainable

Difficult To Retain Staff

Poor Performance

Difficult to Scale

Not a Long Term Investment

What is MVC?
Model-View-Controller (MVC)
Model: Underlying data objects and Business Logic
View: The user interface
Controller: Takes requests from View; passes commands to Model;
chooses resulting View
MVC means keeping these functions separate.
Why MVC?
The shift to MVC
Brian Goldfarb, director of developer and user experience platforms at Microsoft.
“In the same vein, Microsoft has recognized the importance of the MVC pattern
to developers, and it views it as a proven, robust way of making applications,
The needs of customers have changed now.“

Application Generation

Each Screen Format has business logic indexed

UI Events Removed from code

Indicators and UI messaging converted to standard messaging

I/O Standardised into generic components in Java/C#

Procedural Code is converted to event driven code

Standardised Parameters and API’s

Variables rationalised back to DB Fields if Possible

Each Screen Format converted to view technology JSF/ASP etc

Controller Bean/Handler per screen

Uses a open source application framework as necessary or useful
How is the design Re-factored?
Web - JSF JEE MVC
Project Methodology


Project Discovery
Proof of Concept
◦ Migration of a defined subset of functionality to primary desired variant.
Customer can then inspect and benchmark actual migrated code.

Model/Application Preparation
◦ Complete documentation
◦ Application Subdivision
◦ Model/Application clean-up/refactor


Test Case Development
Migration
Training
Global & Specific Customization
On Going Changes during Project

High Level Automation minimises impact of change

Precise impact analysis upfront in tooling

Last minute input
Testing

Distributed and so focussed and more manageable

Consistency – code is consistent so results are more predictable

Semi automated – OO and Event code model allows for automated unit
testing
Future Maintenance

Potential for Automation – Consistent structure

Distributed Architecture/Modular/Known(you know where to make the
change or enhancement)

Object Oriented - reuse

Semi automated – generation from models
Stability & performance

Distributed Architecture

Modular Scalability

Modern frameworks – Hibernate/Spring/nHibernate

Automated benchmarking
