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.
