Research and Design of Process Data Warehouse for Business Process Assessment

Business process optimization occupies a very important position in any corporation, the root of optimization lies in the mining of process logs. However, the log data in different information systems is often heterogeneous, for ease of process mining, they must be processed together in an united way, and data warehouse (DW) technology is the best choice. Appropriate process warehouse structure becomes the key to the research. Based on existing business process assessment model, this paper designs a process assessment-oriented process warehouse for storage and management of process instance data. It can be applied to the process mining, assessment and optimization of event logs. Finally, a case study demonstrates the concept given by this paper.
