Based On Data Warehouse Decision Support System Research And Implementation

Data warehouse has became one hot research field in current Information Technology field.The traditional database is the main information source of data warehouse system.Through the technology of On-Line Analytical Processing, Data Mining and so on, data warehouse can analyse a great deal of data and information and transform data into information.The results of analysis can support the governors' decisions.At present many data warehouse products have appeared on the market.But data warehouse is a project, not a product that you can buy on the shelf.ln order to avoid a data warehouse project meltdown, many key technologies need to be further studied.This thesis introduced the theories and technologies of data warehouse, and then established the architecture of DSS based on data warehouse and discussed the relation between data warehouse and DSS.Some of key problems about designing and implementating of data warehouse are concentrated on. Finally, as a good case in point, some ideas of designing and implementing data warehouse mentioned in this thesis have been applied in Business Analyzing System based on Data Warehouse project successfully, which is useful for constructing the whole enterprise data warehouse in the future.
