A mutil-data warehouse model for supporting enterprise group decision [mutil-data read multidata]

Group desicion support system (GDSS) is an important part of CSCW. Data warehouse (DW) provides the supporting for OLAP and DSS. But most present DSS based on DW don't support well the cooperative decision among decision-makers. To give the enterprise group decision a better support, we put forward a new multi-data warehouse model (SEGDD-WM). This model aims at the analysis of different productive activity of enterprises, which can not only provide assistance for cooperative decision among decision-makers but also support decision service about some subject and united cooperative decision supporting platform for decision service. According to this model, we also provide a group decision (GD) process of a retail enterprise, and explain the feasibility and validity of this model based on experiment.
