Data Organization And Model Of The Data Warehouse Based On The Domain

The technology of data warehouse is a new technology of database application. The technologies of on-line analytical processing and data mining are the technologies based on the data warehouse.The technologies of data warehouse, on-line analytical processing , data mining and the relationships of these technologies are summarized in this thesis. The technology of OLAP based on data warehouse is introduced, and the data model of the OLAP is studied. The data mining technology and its concept and features are introduced. And the data modeling technology of data warehouse is discussed. The method of data modeling of data warehouse is analyzed. According to the characteristics of domain data, a data model based on data warehouse is proposed, taking the data about military for example.At last, the technology of data organization is introduced; the structure of the data organization is discussed in detail. A new model of data organization based on military data warehouse is presented, and it can greatly help to decision-making.
