Kaldeich & Oliveira e Sá (2004) incorporates business process within his approach with combination of data
driven, user driven and goal driven approach [4]. The approach starts with analyzing the source data and produces
the Entity Relationship (ER) diagrams. This approach investigates the business process and produces business
process for current process (AS-IS model). In this approach end user will be interviewed and will produce a TO-BE
business process model. Then the models (AS-IS and TO-BE models) will be integrated to form a new Integrate-
Process-Diagram (IPD). The IPD is used as comprehensive DW requirements and will be verified through interview
with top management to ensure it could lead to achieve business goals.
