Title - ‘The’ African Oil Company Data Warehouse
Implementation
Author - Richard Magnin - Engen Petroleum
Monday, 17 April 2000
Engen Petroleum
Engen’ s vision is to be the leading African oil company' committed to
meeting the agreed needs of its customers in order to increase its
business interests and profit share in Africa.
History - Engen was previously the wholly owned subsidiary of the US
multinational , Mobil Oil Corporation , up until 1989 when it was sold to
GENCOR a South African company. It subsequently became the first
listed oil company on the JSE . Petronas, the Malaysian Oil Company,
purchased a 30% shareholding in Engen in 1997 and 1999 acquired
the remaining shareholding . The company was de-listed from the JSE
and in late 1999 World Wide Africa, a black empowerment group
acquired a 20% shareholding in Engen.
Engen has an annual turnover of $2.25 Billion
Engen in currently represented in over 25 African countries including Namibia,
Botswana, Lesotho, Swaziland, Mozambique, Zimbabwe, Malawi,
Kenya, Burundi, etc
Engen is an integrated oil company operating in both Upstream and
Downstream activities in the industry. Upstream activities ( exploration
and production ) are conducted through Engen’s subsidiary Energy
Africa. Downstream activities ( refining and marketing ) have resulted in
Engen capturing 23% market share in South Africa and include :
Crude Purchasing
Shipping
Refinery (100 thousand barrels per day)
Oil and Grease Blend Plants
Transport
Chemicals & special products
Convenience Stores
Why Engen use Data Warehousing
Data warehousing in Engen has a fairly long history. We started by setting up
a file server in 1992 on which we stored Dbase (dbf) file structures. By
1994 we found limitations with files of 1 million plus records and moved
on to an Oracle database on a Novel server.
We developed an Executive Information System (EIS) at this time but found
the warehouse processing capability too small and thus did all
processing for the EIS on the mainframe in SAS. Then bring the results
to the network and delivering from dbf files using a product call Pilot
Lightship (now Pilot Decision Support Software) as the front-end.
A marketing Management IS was developed in 1997 using the same
approach but delivering with a Visual Fox application developed inhouse.
This fragmentation of environments & developments, a database not readily
available to all, resource intensive application maintenance and of data
collection caused a rethink of our approach.
An initiative to use the Balanced Scorecard (BSC) as a means of measuring
the progress of Engen towards its strategic direction was started and
this clearly identified the business information requirement from the
Chief Executive Office down to levels 3 and 4 within Engen.
The clarification of the BSC, the identifying of the technical and physical
environment, the need to deliver to at least 400 users and the
fragmentation of the business and technical metadata identified that
our then current data warehouse strategy would not deliver the
business needs in the medium to long term.
Data Warehousing - Scenario
Data warehousing must be seen in a complete picture and the designed
architecture must incorporate this.
All aspects of data warehousing should be included from Sourcing, Extracts,
transformations, loads, user access through query tools as well as
deliveries required and agreed to by the business users.
When proposing tools or explaining the operation of a warehouse it must be
remembered that users are mainly interested in Interface and Usability
of the analysis environment and applications and not in the tool set
itself.
An internal group was set up to identify and establish the Ideal and Engen
specific data warehouse infrastructure. Including the technical and
physical environment, the types of tools and identify the personnel
required. Consultants guided us.
All levels of DW Architecture and Data Modelling was done with an
independent consultant who then trained our current data architect
Selection of software was done by 3 members of the data warehouse and the
final choice was presented to the IT group (to ensure technical support)
and to the General Manager level steering committee.
Selection of staff for the data warehouse was then made.
Implementation of the data warehouse followed
What is different
A business driven solution using IS technical skills to support the
infrastructure but business analysts to develop and support the
information deliveries.
The warehouse therefore requested that the following individuals continue to
report to and be managed by the IS Manager.
Database and System administration support requirement would not be full
time and a sharing of these resources, with SLA's, would serve Engen
best.
