OFA development and administration (BAF system, os=AIX on Bull ).

This project took place during heavy reorganisation of this company. A merger
with USG took place. A new SAP based backoffice system was introduced and
source data had now to be read from both systems and integrated. Semantic
mismatches between these systems had a big impact on delivering the system.

Also the organisation had trouble in delivering the correct files to OFA. A
large number of users (over 750, both snapi clients and web clients) had also
a big impact on the system. Database sizes were over 60 Gb. So size and
performance of the system was out of control. Because of this, performance
improvements had to be made. In the end, this project was sucessfully

A version control system was introduced and all upgrade actions were done by

Aug 2001 Feb 2002 Value Boosters
Started my own company (Lucide) and worked for Value Boosters on ...

+ Express systems ( eg Oracle Financial Analyzer )
+ Information Analysis
+ System audits

Part of the work was at Budget Rent-A-Car, a company in reorganisation

Budget Rent-A-Car had an implementation of an ODS (Operational Data Store)
which held over 80 Gb of data at that moment.It considered putting OFA on top
of this system.

I have setup a little datamart for OFA in the Oracle RDBMS (mostly views), and
build a prototype in OFA in two days, which used embedded SQL for retrieving
the data from that datamart. SQL readers were accessible through OFA

Also I did some information analysis for this company to support decision
making for the reorganisation proces.

In the mean time Value Boosters also had some trouble because of malicious
I supported Value Boosters in that area.

Dec 2000 - Jul 2001 Scanmar
PlanCaster product development.

Plancaster is one of the flagship products of Scanmar. Besides Plancaster
Scanmar delivers also a product called 'Market Tracker'. Scanmar clients are
in top-100/500.

Plancaster was a hybrid system which incorporated management planning
techniques and statistical forecasting techniques.

These two sub systems had to be integrated. This was not easy as these two sub
systems used completely different backend setups while Express Objects was
used as the frontend. The system could be hooked into another express based
system to deliver the planning end forecaster functionality.

A bug tracking system was introduced and over 500 bugs were solved, during
this period, while enormous performance improvements were realized.

The system had lots of instabilities, which prevented it's normal
functionality. These instabilities were removed, partly by replacing functions
such as cumsum (memory leaks in that particular version of express) by
