«MEBIUS-UNX» Bank Information System Reengineering

Purpose of the Project

To transfer «Mebius-UNX» Bank Information System onto the new tool and technological environment with the purpose of organization Deployment, Maintenance and Evolution.

Objectives

• To describe design solutions in form of the system model consisting of a set of the diagrams reflecting the existing state of the system.
• To re-structure the system
• To complete model built by automatic reengineering with additional diagrams.
• To provide portability of the banking system into new tool and technological environment

Reengineering: Technical tools

Hardware: PC Intel Pentium 100, RAM 16 MB

Operating System: Windows 95

Software:

• CASE tool Rational Rose 3.5 — for Program code reengineering
• SILVERRUN — for Database reverse engineering

Solution

Automatic reengineering results in the following class diagrams:

• CSystem Libraries
• CProject Libraries
• CApplication Libraries

Analysis of source codes results in:

• Use case Model
• Use cases? realization
• Interaction Diagrams

Metrics

• Number of source files — 10,000
• Number of reengineering classes — 540
• Reengineering Time — 25 hours
• Number of Use Cases built — 103
• Number of diagrams built — 1056

Results

• Models of the system necessary for its development and support are obtained.
• Restructuring of the system allowed to dramatically increase its flexibility.
• Version of the system is generated and fixed in PVCS Version Manager.
• Recommendations for further development of the system are worked out.
