Reverse EngineeringPrime2 to Prime1 using FME

Bronagh Mc Gann

Prime2 – Object Orientated Database

Prime1 Ecommerce Supply System - no longer updated

Updated Prime1 needs to be reengineered from Prime2

Approaches:

1. Converting Prime2 to a Prime1 GFO (automatic)

2. Writing from the Prime2 Oracle database to our current Prime1 EcommSupply Oracle database (automatic)

3. Extracting Prime2 updates, out putting to GFO format to enable Graphic Operators to update Prime1. (manual)

Why?

Project Aim: Update 2000+ new buildings and immediate environs from the Prime2 Database

Workbench Aim: Create a Prime2toPrime1 GFO for Graphics Operators

Process: Graphic Operators open the Prime2toPrime1.gfo and the original Prime1 and manually digitise the updates from the Prime2toPrime1 data to the Prime1 file.

Workbench Outputs:
